Paint blisters

[harowalt]

Hello Corvette experts,

I have a '72 that I am thinking about a new paint job. A friend of mine has the same color same year t-top corvette. After he painted his blisters began showing up in his paint on the rear deck. He was told that oil probably leached thru the underside. He ground out the fiberglass & replaced it with new. 2 years later new blisters are appearing on the back window sides(? whatever the slope from the window to towards the rear of the car is called). I believe he has tried epoxy primer but not sure.

I may run into the same problems when repainting mine. Any ideas?

Thank you for your help.

1st - You posted this in the HELP section which is for help with using the forum itself, not help with vette "issues." You may get better/more responses if you repost in the GENERAL or PERFORMANCE/TECHNICAL section(s).

2nd- I'm definately not a paint expert (or anything else for that matter) as I've not gotten to that point in my restoration yet... but there could be any number of reasons for your friend's paint blisters. Not sure how oil oil would get on the underside of the rear deck for it to leach through, but who knows? How much experience do you & your friend have painting cars? Preperation is key and fiberglass is obviously a whole different medium than typical auto sheet metal. Lots of info out there for fiberglass work, substrate prep and materials/techniques to use when painting. Research, research & more research are your friends with skill & a bit of luck thrown in too!
