I am having my car painted and the shop is advising me to go with DCC single stage paint. I haven't heard much about this type paint, mostly hear about dual stage, color and clearcoat. Any help would be great, thanks

Re: advice re: single vs dual stage paint
My personal opinion is that PPG DCC is the best choice for painting a solid color car that there is! I use it on every car except those that get painted in lacquer for judging. It is a very easy paint to touch-up, is incredibly durable and rubs out looking about as good as a clearcoat job. For metallics, I would probably still go with a clearcoat system, but anytime you go with a clear system, you add unnecessary work to any touch-ups. I have never had a job turn out badly with DCC. It's commonly known name is "PPG Concept".

Re: advice re: single vs dual stage paint
Tom,
Yes, Your car was originally painted with Acrylic lacquer, and all touch-ups should be with it as well. Some colors, especially metallics are very hard to touch-up however. The color can be matched by any competent painter, but the size of the metallic particles have changed over the years, making a perfect match very difficult.

Re: advice re: single vs dual stage paint
I have used a single stage urethane when painting both my 1961 and 1958 (black). The reason I did so was that I painted them in my garage and wanted to avoid an extra step in the process. I don't know if that reasoning was valid, but I was very pleased with the outcome. With color sanding and buffing the finish was mirror-like. Also, when I had to re-paint certain areas, it blended well. I initially used the PPG system, but then went to Valspar's system (House of Color) for the 1958. More economical and the results were just as good.Comment

Re: advice re: single vs dual stage paint
I read that is is not a good idea to color sand/ rub single stage acrylic urethane due to removing UV protection, can you comment? Also, is using single stage on metallic a show-stopper or just not recommended? Thanks in advance!Comment

Problem with wet sanding and polishing PPG SSP
I'm about to paint my 67 black coupe and have faced these same questions. I decided against its use. Here is what I learned about the PPG single stage paint (SSP).
PPG's DCC is a good paint. It is an older paint technology. PPG Nexa is the next generation PPG single stage paint. PPG Nexa will produce better results. I think there are a lot of different brands out there that are a high quality, and what works for a person should be what they use. The problem with this PPG single stage paint is that when you wet sand it and rub it out w/o clear, it removes the hardshell that forms after you catalyze. The wet sanding and rubbing knocks off the outer shell, leaving it more susceptible to UV problems, etc. My research also suggests that once you knock off that outer shell protection, the paint dulls over time. Also, wet sanding and polishing will void the PPG warranty. You don't run into that problem with BC/CC since you only take a small layer off when you wetsand and polish with BC/CC.
Just my two cents.

Re: advice re: single vs dual stage paint
This sounds like B.S. to me. I have been color sanding and polishing single stage urethane paints for years, and have never heard this, even from my PPG dealer! The paint is a catalyzed homogenous layer, and I can't imagine that the top layer is any different than the bottom. As to the level of shine, I will put the shine of my single stage paint jobs against a BC/CC paint job any day. The shine is incredible, and the finish is very durable. It may well be, as another poster said, old technology, but it still makes for a truly beautiful paint job, and many, many custom painters still use it almost exclusively. There are many good single stage urethane paints out there and most will give just as good a result. As to the issue of the warranty on the paint being invalidated by rubbing the paint, I believe that just is not true.
I will ask PPG the next time I am talking to their tech support people, but even if it was true, I would still use DCC and color sand and rub it! I have never had an occasion to ever ask PPG to warranty any finsih that I have bought from them in 35 years, with the exception of some color match problems, and that was an issue for the local supplier and not PPG. There are a lot of painters and suppliers that will tell you anything to sell you on their particular product and process, which leads to a lot of mis-imformation. There are many shops that will tell you that the the EPA has banned Lacquer, and that it is no longer made. This is simply because either they do not know how to work with lacquer, or don't want to, so they choose to lie to people instead.

Re: Problem with wet sanding and polishing PPG SSP
Actually, Nexa is a completely separate brand of paint, and not a paint type.
It is owned by PPG, but is it's own paint line which ranges from water-borne basecoats to single stage urethanes, to enamels. It is a brand which is usually is associated with large collision repar chains, and is not even sold directly by my local PPG refinish dealer. It is a big European brand that has a strong base over there. It is like the OMNI line of paints which are usually only used by repair shops and their stated purpose is to offer the Collision repair shop a cost advantage over other paint lines. These shops tend to push the brand that they have a purchasing program with because they can make more money. I am sure that it is a fine paint and will serve you well on you Corvette, but to state that it will perform better than Concept or any other Single stage urethane paint is probably just hype on your painter's part. For the most part, any good single stage Urethane paint from any of the big name manufacturers will perform about as well as any other, and will last a long time. I have been shooting PPG products for a lot of years, and they have served me well, so I can only report what I know. I will not offer my opinon on other lines of paint because I do not shoot them, but DDL lacquer, and DCC urethane have performed well for me for many years. I will tell you that color sanding an buffing single stage paint jobs is an accepted standard for a lot of custom paint shops that turn out outstanding paint jobs. My gut instinct is that the shop that advises against the color sanding and buffing of paint jobs, probably just wants to get the job out the door sooner and does not want to mess with it. I can not understand why color sanding takes the "hard shell" off of colored urethanes, but it apparently does not do the same to clear urethanes. If you want a glass-smooth surface, you must color sand and buff, no matter what the paint system or brand.

Re: advice re: single vs dual stage paint
Like John, I have been using PPG products for over 15 years. I have used the DDL lacquers and the single and two stage urethanes. I have color sanded and buffed numerous single and two stage paint jobs with no problems. I looked at a midyear that we painted in 1992 or 1993 and the paint is just as glossy as it was when we finished sanding/buffing.
I have learned the hard way to color sand the next day after painting. I waited 30 days on the first one that I did and it was like trying to sand concrete.
Paints are like computers. Buy today and tommorrow someone will come out with a supposedly better product. But I am from Missouri, ya gotta prove to me that another paint is better for my use.Dick WhittingtonComment
