Need help! Is it ok to use bondo on top of fiberglass for car hoods? I used bondo to smoothen and shape a fiberglass hood, but realized that the hood will have a lot of expansion and contractions. Will bondo react with this? Any tip is greatful
Marriage made in heaven! As long as the bondo isn't super thick (not a good idea anywhere), it will do super on fiberglass. Much more compatible than bondo and steel.
The scoop I did on my 'J <<< was fiberglassed on and the imperfections filled with minimal bondo. You'll be fine, just (as willys says) don't use it too thick or structurally.
so then it would be great for my glass spoiler, ala 72 camaro? i thought this plastic bondo was almost the same, just different.
