Default Need help! Bubbles in paint?

I am looking at a 69 vert to buy and there are bubbles in the paint. The owner sayes it is from laquer primer. It was painted around 1988/1989.
He had the car chemicaly stripped as well. I am not sure if the primer is the cause or the chemical stripping is the cause for the bubbles.

If anyone as some ideas or if it can be fixed let me know.
Thanks

It could be a lot of things including the primer. It could also be solvent pop or contamination in the fiberglass when stripped. This may be the stripper used or it may be something else in the fiberglass.

The only way you’ll know is strip it down to the fiberglass and start over. Even then you may not find out!

Willcox is right, it could be anything from the stripper not being washed off properly to mousture in the airlines when it was painted. It doesn't matter what it is though, the ONLY way to get rid of it to remove it and start over. If your looking for someone to give you some it'll go away kind of answer it won't. It's a nice looking car by the way.

I like the car a great deal and am very close to plulling the trigger on it.
I just can't get past the bubbles in the paint. I was hoping to get another 4-5 years out of the paint before repaint.
thanks for the replies!
If anyone else can put there input in let me know?

Chemical strippers tend to stay in the glass and eventually bubble up. All the experienced fiberglass body men I have spoken to all agreed..."don't use a chemical stripper". More work to sand, but better results.

Use to work at my uncles body shop while going to school. He always called this fisheye, which ment there was something under the paint causing contamination. Stripping is the real way to solve the problem. But if don't want to do that try sanding the bubbles smooth and spray on a few coats of a good sealer then paint. Ask you local paint supply for a good sealer.

Still working on the issue and trying to get to the bottom of the bubbles. A body shop guy I talked to said it might be the laquer primer.
but still could be other things?

A true bubble and a true fish-eye aren't the same. A fish-eye is almost level compared to a bubble. It is typically caused by lack of adhesion due to failure to remove silicones and occurs much quicker after spraying. In any event, the OP has good cause for great concern.

Why anyone would use use stripper on a vette is beyond stupidity.
