Paint Peeling
Has anybody had this issue before?
It'* officially know as "Delamination". I know there was a class action lawsuit against GM for cars built from the late 1980'* through I believe 1997. Apparently it has to do with new environmental laws forcing auto makers to change the way they painted their cars. My car is too old to get anything back from that. I don't want to spend $2000 or more to get a decent paint job, and I don't want to get a cheapo paint job that will dull after a year or two. I was thinking of doing a job with paint cans just so it'* not so obvious and prevent any rust from starting. I don't want to start though until I know how bad it'* going to get. I was thinking of starting by doing a light sand, then use some primer, maybe wet sand it, hit it with 3-4 coats of color, then a few coats of clear coat with wet sanding between coats (maybe except the last color coat?) with a 400 or 600 grit sandpaper. Does anyone have any tips on the best way to do this? Am I wasting my time and effort? Eventually I'd like to paint the whole car but right now I don't have a compressor or paint gun etc.
Thanks.

I have that issue too... A Battery of the White GM Cars through 95-96 have this issue..
Had something to do with the way they were painted.. If you look at your Primer you see that even though its not shiny, it is as smooth as Glass.... I have been told in the past that the Primer was so smooth that that the color coat did not bite or adhere to the Primer correctly, and later on down the road this would cause Paint Peel..
My White 91 is doing this right now... I can go out and Peel the paint off in sheets.. I hope to Fix this in the next couple of Months

I have the same problem on my '92 Chev truck. Looks like crap but nothing that I can do until we get some warmer, dryer weather. In the mean time, I'll just keep peeling off the loose stuff so there is less to sand off when the time comes.

I don't know that I would bother. If it'* as bad as jr's3800 says, if you spot paint the areas that are bad now, chances are it will end up peeling in other areas later. Maybe just shoot a few coats of color so it doesn't look so bad and leave it at that?
Check into the local schools and such otherwise. I've heard some people say that if you supply the paint you can often find a local body shop class that will do the work for you as part of their learning.

It will eventually all peel.... No if ands or buts... It will happen, just a matter of when..LOL
I have seen some that have held up incredibly well, I think one factory used a different process than another.... I have seen white peel like crazy time and time again... and on others I have seen them look great...
If you look at the white on todays GM cars you'll notice its not ultra smooth... They don't seem to have the peel issues either..
On the 87-96ish GM cars you'll see a lot of the white cars that look smoother than glass.. I think these cars have primer that way too smooth... It was an issues with the Paint adhering...
I am interested to see how my car will look once I get the Car all stripped and sanded, primed and painted... I want the paint to adhere to the primer and stick..

I'm wondering if it would be ok to paint over the primer with a light sand or it will have to be sanded down to bare metal...
