True. Thank God I still have the original Bright white paint job from GM, although I did see one in my neighborhood with the same car as mine with paint peeling off his car. I was concerned and when I did have my car side swiped, thats when I asked the GM bodyshop about the procedures GM made on painting cars.

The GM body shop technician told me that they run off an assembly line, that shoots electromagnetic paint procedures that paints the primer very quickly and then processed to be baked. Once baked it is it baked at a very high temperature and then painted without roughing the primer and thats why some cars have problems with their paint. Knock on wood I dont have that problem. But the GM body shop tech noted to me that if you dont rough up the primer it wont stick as easily as if it was roughed up to be painted after the baking process. So thats why some car have problems and also maybe due to the fact that some owners neglect to wash or keep up their cars finishes.

also remember this, its not what your car is painted with, its whats underneith it. Covington Pontiac of silver spring, MD. bodyshop!

Yup, if primer wasn't sanded properly before applying the color coat, then you will have problems. No matter how well you wax paint, if it wasn't painted in the right process, it won't matter how much you wash and wax it. But I guarantee this doesn't happen today. I bet any mistakes that were made regarding the primer, they are old problems that have been resolved. No worries.

The only problem with GM paint finishing that I have found is.

1. Paint will bubble and crack due to rust
2. Clearcoat will peel, paint will not

My '92 only had a bit of rust by the rear wheel well on one side and a touch on the lower front door at the bottom. That was how it was in 2002 when I gave it to my brother. I never had any other problems concerning or having to do with paint.

I do remember the older grand am'* having some serious paint peeling and rusting problems, but that was in the eighties, possible the early nineties.

That was due to a very short (and not well thought out) period of time that GM used a different primer. We had an aftermarket paint job on our Blazer for this reason. I've seen that on almost every GM model from that era.

Yup, I echo what Jim W said. My paint is fine on my '96 but the clearcoat is beginning to peel. Not sure whether I'm going to wet sand it down or redo it. Ah well, its almost over 8 years old I guess, what can ya do...

Try 'Liquid Glass'. Industry secret

Simulates a clearcoat, but goes on like a wax. A couple coats, and a good hot day to cure/level it, and you might not see it.
