May - June 98 ROCKY MOUNTAIN CHAPTER Issue 5 & 6
CHAIRMANS COMMENTS
By Dennis Kazmierzak
This past two months has gone fast. With our newsletter published every other month, the communications within the Chapter relies on e-mail and the general meeting. If you are not on line you may be out of the loop, but if you attend the meeting youre back in the loop. So you dont really have to have e-mail, but it would make your information easier to get and quicker.
To recap the Chapter activities over the past few months, we have put "JOE" together and sent him off to the UK, thanks to the efforts of Jim Lennartz, Jack Humphrey and Butch from Golden Auto Parts. "JOE" (Jolly Ole England) is the tag put on the engine for Barrys Corvette. A few others pitched in but the main effort was by the fore mentioned. Im sure Barry Morris of the UK Chapter appreciates their effort and concern of building a correct 519 engine for his Corvette. Several of the members attended the Southwest Regional with a very good result in the judging arena. Jack Humphrey will have more to say on that in this newsletter. We also had our annual meeting on April 18th. The attendance was approximately half of the current paid membership with three new members and a few prospects. I was re-elected chairman and Gary Nesmith vice chairman for 1999-2000. After the annual meeting Bill Bell had arranged a tech session at Country Club Auto Detail, Inc. Jack Farland demonstrated the art of detailing a car and Joe Orecchio got a free shine out of the day. Unfortunately Lisa and Dirk still need paint. The polish job was good but not that good. Sorry Lisa, well get the HVLP system going for you.
Speaking of paint, in this issue I have permission from Ted Kade Managing Editor of Classic Auto Restorer, to reprint the article by Larry Lyles on Base Coat/Clear Coat Finishes. I found this article very interesting and Im sure you will too. Weve all heard about BC/CC and HVLP systems. This article I believe gives you a good idea and a financial view of this decision making process. You be the judge, is it worth the money and time to do lacquer compared to BC/CC.
At the next meeting I will have an updated membership list and a copy of the By-Laws for anyone that requests it. Have a safe drive in your Corvette through the next few weeks of the spring.

FROM THE JUDGING CHAIRMAN
By Jack Humphrey
Southwest Regional
In April, RMC members braved a spring blizzard to attend the NCRS Southwest Regional meet in Albuquerque, New Mexico. This has been an annual meet rotating among sponsoring chapters (New Mexico, Southwest, Bonneville, and Southern California). Ive found it an excellent meet early in the year tucked typically someplace warm and nearby. I was not disappointed!
This year it was payback time. Our friends from New Mexico pitched in with help and cars for our judging field in Steamboat and we returned the favor. Six RMC Corvettes participated in a field of roughly twenty-four pretty equally divided among Flight, Founders, and Performance Verification entries. Two RMC members (Bill Bell and myself) drove our Corvettes to Albuquerque (538 miles by my odometer) leaving one day early and just beating the blizzard that struck Denver.
This time my Corvette commute to a regional ran smooth as silk. Lil Red Riding Hood, my 71 small block roadster did nothing naughty (exception sticky passenger door lock). As Bill Bell, RMC Activities Chairman, and I played Corvette "tag" on the trip down with Jim Lennartz, RMC Vice Chairman, riding shotgun and relief pilot, my mind wandered to Zora. Here were two classic Corvettes (71 and 64 FI coupe) cruising the American freeway system effortlessly 30-40 years after their design and build. What vision Mr. Duntov executed!
At the meet, five of six RMC entrants hit paydirt. Bill Bell breezed through his Founders Operations Check. John Alpers, Bill Baker, and I captured Top Flight ribbons. Bill Bell and I shared the meets Longest Distance Driven award.
Martin Egan cleared the decks for his assault on this years NCRS National Convention by passing the Performance Verification. Martins 77 Corvette with 3900 original miles is now fully qualified to vie for the NCRS Mark Of Excellence and Bowtie awards simultaneously. Few Corvettes in history have the pedigree to try let alone succeed .
Howard Loomis in his 82 was the only RMC casualty. Just a few check blocks into his PV, the "deadly" horn honk test extracted its toll. Initial taps on the horn ring resulted in an amazing explosion of the horn ring into its constituent components. During PV tests, owners are allowed one repair not to exceed fifteen minutes. But, a Catch-22 (NCRS Judging Reference Manual) prohibits part substitution once a car is on the Judging Field .
My heart goes out to Howard. I remember towing my 65 to the NCRS National Convention in Anaheim, California (blazing summer sun beat the desert and there was NO air conditioning in the tow vehicle). My PV was scheduled for the last day of judging. A vent window failed to close properly (an easy adjustment and my sole PV repair).
Then, when I was told to crank er up nothing! The classic dated diodes in my alternator had failed baking in the sun and the car sat across from Disneyland for the better part of a week with the battery short-circuited. I know the disappointment Howard felt. Its a lot of effort to haul to a meet, fail a PV then live with the results driving back. But, fortunately, at NCRS theres always a next time and I know we all wish Howard our best!
School
The atmosphere on the judging field in Albuquerque was warm, friendly, and educational. This was helped in large part by a judging school Roy Sinor commissioned. We attended a professional slide show aimed at improving scoring consistency and judges conduct. We were impressed with the professional nature of the schools FDICC presentation, especially its examples and audience interaction.
FDICC is the factory concourse scoring system that has been used for years by the National Corvette Certification Board at Bloomington. It teaches there are five indices in assessing originality. "F" is finish and it pertains to an items texture, color or coating. "D" is date code and items that were dated should appear authentic and agree with published NCRS guidelines. "I" means installation is the component affixed according to known factory original tolerance, manner and position? "C" refers to completeness, ask if everythings there. The other "C" is configuration for the concept of component shape, style, and markings.
School taught judges not to write "reproduction" in a comment field and blindly assess a 50% point deduction. We were urged to use the five axes of FDICC, clearly explain each originality deviation and use the NCRS 10-90% judges deduct discretion accordingly. Students were lectured on the role of an NCRS judge help the owner earn the NCRS award. These are good guidelines that ARE fair!
I personally think more thought needs to be applied to FDICC in the area of coatings. As taught a component thats heavily coated, would lose 25% of its originality points (finish) and receive 100% of its condition points. My point is this could be unfair.
What if a part is so heavily coated judges cannot appraise the underlying surface? Date code determination, supplier marks, the presence of other components like lock washers and the reasonable assessment of condition like surface pitting becomes impossible. Why bother to do a meticulous frame-off restoration? Why not just shoot everything in sight with gallons of undercoat or paint/plate the heck out of source identifiable parts to obscure them?
This is a minor issue, easy to solve. Simply amend FDICC guidelines and give judges the discretion to deduct for those aspects of FDICC originality as well as condition that are obviously obscured by coating. Basically, Im happy with the FDICC approach and believe it can only improve NCRS.
Coming Attractions
Mr. Sinor informed us of a few new "goodies" under study. One, code named Sportsman Award, is aimed at expanding NCRS meet attendance to ALL Corvettes regardless of age or factory authenticity. Its intended to attract both the "show and shine" crowd as well as street modified cars.
The second "goodie" didnt have a name. Its focus was on opening the judging field to Corvettes with a racing pedigree. The Gulf cars were cited as examples. I have something to add.
If this area recognizes only those Corvettes with bona fide historic race pedigrees, well lose market share. There are many more cars out there that have been recently competition modified like those on the track at Steamboat. Why close the door to any Corvette thats legitimately Chevy powered? Perhaps this area could/should have different divisions (new, historic) .
This newsletter announces our annual Chapter meet scheduled for June 20th at Stevinson Chevrolet. Any NCRS member wishing to have their Corvette Flight Judged is urged to complete the registration form. Plus, Ive given equal copy space to those who want to participate in the judging. Remember there are only two qualifications for being an NCRS judge you are a member of NCRS in good standing and you agree to obey published NCRS judging guidelines. Theres no better way to get up close and personal with a wide cross section of Corvettes than to be a judge. Chapter meets are your invitation to have fun and learn. Come join us for a day of fun in the sun!
Last, Barry Morris, Vice Chairman NCRS UK Chapter, and RMC member flew from London, England to join our caravan to Albuquerque. WOW! When will we reciprocate? Answer: August 1-2, 1998.
Barry took the podium at the awards banquet in Albuquerque to present Flight 98, the first NCRS Flight Judging event outside North America. This is set for the first weekend in August and I have registration forms for any RMC members who are interested. Right now I count eight of us planning to cross the pond. Most will bring the ladies (hear that girls England is calling!). Come on, folks, cant we muster a double-digit showing? This IS history in the making .

ALL CORVETTES ARE NOT RED
By Jon Whiteley
I received some friendly ribbing last year from one of our members about the color of my Corvette. It seems to this kind soul that green just isnt an appropriate color for a Corvette and that "all Corvettes are red" (No, it wasnt James Schefter). I thought it might be interesting to gather the available data and learn just what the most popular colors were over the years. The chart that follows is based on the information published in the NCRS Spec Guides by John Amgwert. I think youll find some surprises.

BASE COAT/CLEAR COAT FINISHES
If You Want Durability for Your Driver, This is the Way to Go
Nothing in the world looks better on a car or truck than a hand-rubbed lacquer paint job. I repeat nothing. But while I love the look lacquer paint gives, the time came when I could no longer afford the redos lacquer paint caused. I needed something better. Enter base coat/clear coat.
I could go on for hours with technical jargon about base coat/clear coat finishing systems, and why they are superior to anything weve used in the past. I wont, however, because basically what it comes down to is one factor durability. Base coat/clear coat finishes, which consist of a color base coat and an acrylic urethane clear coat, really last. Nothing I have worked with before even comes close.
I know, youre thinking lacquer came on the 59, so lacquer should go back on the 59. If your 59 is a show car and originality is a must, go for it. Like I said, I love the look lacquer gives.
But if your 59 is a driver, consider this. Base coat/clear coat is so durable the manufacturer of the paint system we use, Diamont, allows us to offer a full 10-year warranty on any paint work we do as a certified Diamont refinishing facility. Try to get a guarantee like that with lacquer or enamel.
Aha! I smell a clutch burning. Somebody out there is thinking: How can a paint job last 10 years??
At this point Im going to weaken and give you a word of technical jargon Ultraviolet radiation. All right, thats two words. But that UV radiation is the primary culprit in paint degeneration. In fact, in the body shop business we dont think of a paint as lasting 10 years, we think of it as having "hold out" the ability of the finish to "hold out UV radiation over long periods of time and prevent it from destroying the paint. Hold out is accomplished through the use of the correct primer surfacer, the right sealer, the color base coat and, finally a urethane clear coat. Stopping UV damage by going to a base coat/clear coat finishing system puts an end to that chalky white stuff forming on your old paint job. That white stuff, by the way, is actually paint decomposition from UV exposure.
Which reminds me: Remember all that color left on the buffing pad the last time you polished the 59? Thats dead paint, kind of like automotive dandruff, only your car isnt regenerating a new coat as the old one flakes away. So, the more you rub, the less paint is left behind and the easier it is for UV to destroy what remains. Get my drift?
But you still like lacquer. Besides, lacquer is easy to spray. Well, so is base coat/clear coat, and I know a trick that will make your base coat/clear coat finish look like lacquer, without the dandruff. Fair enough? Lets do some base coat/clear coat.
Comparative Costs
A number of automotive paint manufacturers produce base coat/clear coat products. As I said, we use Diamont, but there are other widely used and equally good brand including DuPont and Glasurit, just to name a couple. The basic difference is cost; so shop around.
I asked our paint supplier to run a Usage Cost Estimate for a typical base coat/clear coat paint job, including everything from bondo to clear. We chose an early Corvette red in DuPont Chroma Base to use as our color. The total cost came to $628.10.
A lot of money? Yes and no. Compare the base coat/clear coat cost estimate to the lacquer cost estimate on the form on page 12. Lacquer came to $403.41. Whats a couple hundred dollars when youre talking 10-plus years in the life expectancy of the paint? Remember, this is 10 years with the car exposed to UV on a daily basis. Your beauty, kept in the garage, may never need repainting again.
By the way, if the supplier you chose cannot provide you with a computerized Usage Cost Estimate similar to the one shown on page 12, find another supplier. If he cant give you a computer-generated estimate, chances are he wont be able to electronically duplicate the color you desire, especially if you are working on an older car.
Do Your Homework
Before you head for the paint store, you need to know a few things. Like, what finish is on the car now? Soak a white shop towel in lacquer thinner. Rub the old paint in a place you know will be repainted or choose a hidden area if you are still uncertain about your plans.
The towel will become stained with color if the paint is nitro or acrylic lacquer. Swelling or wrinkling can occur if the finish is fresh, air-dried synthetic enamel. However, old or oven-dried enamel is immune to thinners. Remember, if the paint comes off, its lacquer. If the paint wrinkles, its fresh enamel. If nothing happens, its old or oven dried enamel.
Next determine if the finish is hard cured. Vigorously sand an area with 240-grit abrasive. If the old finish becomes rubbery or sticky, it probably will lift when sprayed over. This paint will have to be removed before a new finish can be applied. Hard-cured paint will simply sand away. This finish can be painted over.
To check for clear coat, use a sharp knife and scrape gently across the surface. Single-coat finishes will produce a colored residue, whereas a clear coat will produce a milky looking residue.
Now that you know which finishing system is presently on the car, the only other consideration is how many coats. Your friendly automotive paint supplier has a handy little magnetic gauge that will tell him exactly how many mils of paint are presently on the car (ed. note that should be interesting on a Corvette). For base coat/clear coat operation, the maximum total finish thickness is 12 mils (12 thousandths of an inch). A finish thickness greater than 12 mils could result in paint failure due to blistering and/or checking and cracking.
The new base coat/clear coat finish will account for 4 to 6 mils of this total thickness when applied at the proper thickness of four sanded coats of primer and sealer (2 mils), two coats of base color (1 mil) and three coats of clear coat (2 mils). That means your old finish can be as much as 6 to 8 mils thick. If the magnetic thickness gauge reads 6 mils, smile. If it reads 8 ? Its your car. Me, Id strip it.
At this point, the supplier will ask what brand and color you want. Lets say here in the Paintville, USA shop, DuPont Chroma Base is a bargain and you want to go with the cars original color. Youll need the paint code found on a metal tag attached to the core support, firewall, door jam, deck lid, glove box lid or someplace else.
If the paint code is missing, your supplier can determine the color by using an instrument called Smart Scan made by the X-Rite Co. This instrument, when placed on a clean, shiny color surface, can read that color electronically and determine the correct formula for matching it. Any color. Almost. Should you wish to duplicate that weird purple on grannys70 dodge, bring the car. Using the Smart Scan, your supplier should be able to match it.
With information regarding color, the finish the car presently has and the brand (DuPont, in this case) you want to use, the supplier can go to the DuPont Technical information book and determine which finishing system will work best.
Meanwhile, back at the Shop
Your supplier helped you make a finishing system choice (DuPont Chroma Base) and you now own a box filled with paint cans with numbers on them. Dont be surprised if your head starts to spin with thought like, "What the heck are these? What am I doing?"
Relax. Find the can marked 2931K. Thats the red base coat. Look at the Usage Cost Estimate. Under "Coating" find 2931K, the paint. Under it is Cat, NONE, meaning no catalyst is used. The next item is 7175S, reducer. The next is Add. 12305S, which is an additive. Mix these together to form the base color. Note each item is listed in ounces. Measure out each item into a mixing cup that measures in ounces to get the right mixture. I cant go into all the different mixing ratios for each brand, but your paint supplier can. Ask him. Thats his job.
The same goes for the column next to it, "Clear". The cans marked with these numbers will be mixed together when the time comes to spray.
So, what is all this stuff listed under Paint and Body Supplies? Its everything you need to knock out the dents (ed. note another non-Corvette concept)., prime and sand the car to make it ready for paint.
Since our car was kept in the garage and driven only on Wednesdays, it has no damage. If your car is as nice as ours, you wont need all the stuff on the Paint and body Supply list. If it isnt that nice, youll need to do the body work before its time to paint.
Back to the Car
As I said, our car is dent-free. Well begin by washing the car with soap and water. No detergent. Use a good, automotive wax-free cleanser. (Turtle Wax and Armor All are both good brands.) then wipe the car down with RM900 degreaser to remove any wax, tar or road film left behind. To degrease, take two clean shop towels, folded, and soak one towel in degreaser. Wipe the surface with the soaked towel, immediately wiping away the wet residue with the other towel. One towel in each hand works well here. Go over the entire car.
Next, the car must be sanded. Im assuming you already have the car torn down. That is, the chrome and handles have been removed. Sand the car with 240 grit. A DA (dual-action sander) works well here and hard-to-reach areas can be quickly hand-sanded afterwards.
Thoroughly clean the car again with RM900 and this time use a blower to remove any traces of sanding residue hidden in the cracks and crevices. Tape off all areas you dont want painted, such as windows, using ¾-inch masking tape and masking paper. Masking paper comes in rolls of various widths and lengths. A 100-foot roll of 18-inch-width paper should be plenty.
Degrease the car with RM909. Yes, this is a different degreaser. RM909 is water based. Water-based degreasers will remove sanding residue solvent based (RM900) degreasers wont. Now tack the car off.
Shake up the Uro Primer (Check the Paint and Body Supplies list on page 12), thin and catalyze according to directions, and apply four even, wet coats to the car, allowing each coat to flash (dry) for at least 15 minutes before applying the next one.
As this is a catalyzed primer, and we have no bare metal showing, no etching coat is needed. If you experience high humidity and have bare metal, you may need to apply an etching coat before priming. Your supplier can help there. Once the primer is cured (a good rule of thumb is to let it cure overnight), spray on a light guide coat. (Use dark color for light colored primer a spray can works well.) Block sand with a 220-grit dry abrasive until the guide coat is gone. Be careful to not block sand through the primer base, however, as this coating is an essential part of the base coat/clear coat system. Re-sand lightly with 320-grit dry abrasive to completely smooth the surface. Remove all tape and paper, blow the car off thoroughly; then rewrap.
Degrease the car again using RM909. Tack it clean. Find the can marked Sealer, catalyze according to directions on the can. (Your paint supplier can tint the sealer to be a close match to whatever color you chose as your base coat. This reduces the amount of paint you must apply for good coverage.) Then strain the catalyzed sealer through a paper filter into the HVLP.
The HV what?
The High volume, low pressure gravity-feed paint sprayer. In my world we must contend with VOCs (Volatile Organic Compounds) and meet certain governmental pollution emissions requirements. The HVLP spray gun allows us to be in compliance with the law.
Despite the fact that the HVLP was regulated into existence, it is a great gun. But it is an expensive gun. HVLPs range in price from $150 to around $500. A Sata, which is the gun of choice in our shop, runs about $400. But if you plan to paint this one time and never again, dont buy a new gun. Borrow one if you can or use what you have. After I finish shooting this car, Ill talk more about the HVLP.
Spray two coats of sealer, making sure to spray wet, even coats as this will be the base for the coats to follow. If the sealer isnt smooth, the following coats wont be either.
Carefully re-tack the car. Be sure not to touch the sealed surfaces with your skin as the oils will mar the finish.
Shake up the base coat (shake it well, very well), add additives and reducers according to the Coating list on the usage Cost Estimate and strain through a paper filer into the HVLP.
Place a small square of black tape somewhere on a masked area next to a surface to be painted. Don the respirator, painters coveralls and latex gloves and start spraying, Apply two good, wet coats, allowing 15 minutes between coats. Check the black square. If it is covered completely, two coats is enough. An important tip. Base coats are flat no shine much like sanded lacquer. The gloss comes from the clear coat.
Give the final base coat 30 minutes to flash before applying the clear coat. This gives you plenty of time to mix the clear. See the Usage Cost Estimate under CLEAR and mix the 7800S Clear with 7895S catalyst per ounces required. Apply three wet coats, allowing 30 minutes plus between coats for flashing. You now have a paint job.
More Tips
Let me offer a few more tips, beginning with the operation of the HVLP. Maintain a 90-degree angel to panels when spraying and never "arc" the spray pattern. (Think of facing a wall and trying to paint that wall by only moving your arm. You would quickly find that plenty of paint gets on the wall directly in front of you but very little reaches the wall once you arm has extended to a point almost parallel to the wall.) Watch for the wet edge and just overlap it when spraying to prevent streaks.
HVLP produces larger paint droplets than suction-feed guns which result in the solvent staying in the paint longer. Thus the longer flash times. Never spray a tack coat. It is difficult to reflow the drier spray of an HVLP to get a smooth finish.
An HVLPs V-shaped spray pattern is smaller than conventional gravity-feed spray guns. Therefore, the gun must be held closer to the panel, about eight inches away, and spraying is accomplished at a slower pace. Each coat of base color must be allowed to flash for a minimum of 15 minutes and each coat of clear must be allowed to flash for up to 30 minutes. And, remember this, if you plan to spray additional coats of clear (to allow yourself plenty of coats to sand smooth), each additional coat must be allowed to flash 15 minutes longer than the coat before it. Yes, hours can be spent spraying base coat/clear coat. But the longer you allow each successive coat to dry before the next coat is applied, the less chance you have of experiencing solvent pop.
Solvent pops are those nasty little micro pits found in base coat/clear coat paint jobs. They are exactly what the name implies. When a successive coat is added too soon, before the solvent from the underlying coat has had a chance to dissipate, the solvent will "pop" through the next coat creating solvent pops. They do not go away. Ever.
We paint in a heated, high-volume air exchanged booth. Each finishing job is baked and cured in about an hour. Obviously, you wont have that luxury. Thats OK. Catalyzed urethane finishes will dry without the heat; it just takes longer.
Never spray in temperatures below 65 degrees or in extreme high humidity conditions.
Spray in a well-lit, well-ventilated area with some means of exhausting the fumes. Be aware that most fans are not explosion proof and that paint fumes are extremely volatile. Wear a respirator at all times. A dust mask wont do the job. A dust mask is exactly what the name says, a dust mask, not a paint mask.
Our painters wear OSHA-approved canister-type respirators which work well as long as the filtering canisters are changed after a days use. Of course, they also are working in an environment where the air in the spray booth is exchanged for fresh air at the rate of six times a minute. Anyone working in lesser conditions, such as a garage, might want to invest in a hood-type fresh air system.
A good, OHSA-approved respirator costs about $50. A base-priced fresh air system costs about 10 times that much. But ask yourself an important question: Whats the price tag youll put on your health?
Something else to consider when painting is safety glasses. Wear them, even when mixing paint. One bad slosh and you could end up one-eyed. Our painter claims that moving from the air-conditioned mixing room to the heated spray booth causes his glasses to fog up. I have no solution for that. Not yet, anyway.
Keep everything away from flames. Keep the fire extinguisher available at all times. Personal protection equipment such as respirators, coveralls, safety glasses and latex gloves werent invented so they could look good hanging on the wall. Wear them.
Labor Intensive
Perhaps one of the most important tips I can give you is, dont kid yourself. Do-it-yourselfing is a lot of work. I repeat. A lot of work.
We have a car in the shop at this writing that a do-it-yourselfer did himself. The finish looked good. Darn good. Problem is, he got tired. Months of hard work took its toll. He had trouble in one area which caused a redo. The redo was rushed, resulting in the primer being painted over before it had a chance to properly cure. The result was solvent infiltration of the underlayments.
The paint came off in sheets the size of this page. Now hes paying me to fix it. We stripped the car and are now in the process of refinishing it.
Im not trying to scare you. I simply want you to do it right. Base coat/clear coat has the potential to outlast your mother-in-law. Youll be proud of it from now on, if for no other reason than you did it yourself. So go for it, and good luck.
But before you go Remember I mentioned VOCs? Volatile Organic Compounds. Now is a good time to consider: Am I a Body Shop? Our government is getting sticky on this subject. Here in Texas, the Texas Natural Resource Conservation Commission considers you to be a body shop, and therefore must meet all state requirements for body shops regardless of your location (garage?), if you use 2 gallons of paint and solvent per week. Do you?
Before you embark on any painting frenzy, check with the Conservation Commission in your state. Believe it or not, these guys are helpful. And, theyll keep you on the right side of the regulations monster. A case in point. Some areas (Orange county, California, for example) already have laws on the books to phase out lacquer and other high-VOC paint finishes. Texas has the same law, but enforcement is currently lax. So, before you spray anything or dispose of anything paint-related, be sure you are within the law.
That Lacquer Look
Earlier I said theres a method for getting a lacquer appearance from a base coat/clear coat finish. This is accomplished by sanding the car with 1000-grit, then 1500-grit and finally, 2000-grit wet abrasive. Begin by sanding the entire care with 1000-griit, wet abrasive. (Soak the paper to soften it before use and sand with a soft rubber block, never by hand, remembering to keep the surface to be sanded wet at all times during sanding operations.)
Once the finish is dulled with the 1000-grit, the difference between the 1000-grit and 1500-grit papers wont be detectable. For that reason, you should work in small, defined areas, sanding in a circular motion taking care not to pass over the same area more than two or three times. Repeat this process with the 2000-grit and you will begin to notice the slightest hint of a deep luster in the paint. This is the depth you are looking for.
To bring out the rest of the shine, I like to use compound on the variable-speed electric buffer with a clean wool pad. The variable-speed buffer offers better control which means less chance of rubbing through the paint. Our shop uses 3M5974 compound for this process.
So which is it, rubbed lacquer or base coat/clear coat? Only the passage of time will tell.
My money is on the base coat/clear coat system.
