Same paint blistering issue in the trunk, as well.
I assume I need to seal the glass fiber surface with fiberglass epoxy, and then once it's fully cured sand it smooth. Do I use Bondo to smooth out the surface for painting, or smooth out the epoxy?
My plan is to use some ultra high-temp primer/paint to finish the surface.
I'm not a complete novice. I can use a rattle can and make small jobs look professional (It's almost all in sanding, sanding, sanding, and the rest is in the paint strokes).
Any advise for a fiberglass novice?

Without seeing it,it's hard to tell,but if you have exposed fiberglass "hairs" sticking thru,I'd sand them down as best you can with a round dual action (DA sander) sander starting with say 80 grit.....if you can get it down pretty smooth,then I'd go with some fiberglass epoxy to smooth it up, you can get it pretty smooth when applying with a plastic bondo spreader, then sand smooth once cured with the DA sander and paint....I would NOT use bondo under the hood because of the heat....
sanding/working with fiberglass is a dirty job,where some kind of mask and put a good fan on right behind you to help blow away the fiberglass dust.....
