Thread: Need advice priming a fiberglass body

Tweet

I've done dozens of Vettes, kit cars, and street rods. As long as you use a two part primer, the job will turn out pretty well.

My advise is to add a couple extra coats, then guide coat and block with 360 or 400 before paint. If you find wobbles or flaws, use a two-part glaze, like Fiberglass Evercoat's"Euroglaze". Reblock them, and reprime or seal those spots before paint.

Air dried primers can lead to all sorts of shinkage problems after the paint is finished. I've tried 'em all, so don't even go that way!

BTW, no reason for a self etching primer, if it's not on metal. The purpose for the etch is to neutralize rust or corrosion, which doesn't happen with 'glass.
