Default paint bubbles !!

Just noticed on my 86 corvette that I"m getting paint bubbles on my paint I bought the car 3 years ago and have been really taking care of the paint buy waxing the car 4 times a year. Does anyone know why I"m getting paint bubbles and is there anything I can do to fix them ?
Thx for any help

(edit your post - you need a bracket at the beginning of the photo insert)

to try to answer the bubbles thing - did you or the painter use a chemical stripper? the only thing i can think of is it gassing cause by not neutralizing the paint stripper. are the bubbles only on the urethene body parts - front and rear bumpers, rocker panels - ???

Unfortunately there is not much to do, these are caused by either containments in the SMC or the sealer not performing. I had these after my 86 was painted had to bring it back and they sanded and re-shot the hood again, they never did come back.

So is it worth taking it to a paint shop to fix and are we talking alot of money ? I also have some on the hood and under rear view mirror.

Talk to the paint shop. I have the exact same thing on my '85 I painted last year. I am a professional painter, I've painted a dozen or so Vettes over the years with no problems. Mine is on my hood and on the upper half of my drivers side door. As someone mentioned it could be the sealer failed to perform, or contamination. Chemical stripper is a good guess but not necessarily the problem, mine has never seen paint stripper.

Be polite when you talk to the body shop. This might not be the result of negligence on their part Fiberglass is tricky to work on compared to steel, more susceptible to contamination. It does happen from time to time. See what they will do for you. A lot of this will depend on how much you paid for the paint job. If it was a $1200 job they will probably tell you to get lost. If you paid $5,000 they should be willing to work with you.

Thats very strange...my 85 is doing the exact same thing in the same spots! Yours isn't black, too is it?

When you refer to sealer, do you mean some thing like prep-sol or something similar, or a sealer specific to SMC?

Blisters come from moisture in the fiberglass that wasn't removed with heat lamps before it was painted. They usually don't show up right away.

That is an excellent point. When I pained my '85 I was in a hurry and painted fairly soon after wet sanding the primer. Since it was my own car I didn't think much of it. It was also humid as hell when I painted it.

Whenever I do a customer car I always wash the body then let it sit for several days to let any moisture escape and ensure it dries completely. Damn I should have thought of that...
