I got a side skirt that didn’t fit very well. Shows some gaps and I want to
cover the gaps up. Will bondo stick on to fiberglass material?
You could use bondo probably but I would use Duraglass if you are making a minor change like that to it. If you need to make a big change then you’ll want to go a different route.

Yes, it will but make sure its warm. It will only cure when its warm but otherwise yes. I shaved my emblems and antanna with fiberglass then bondo on top.
Bondo cures by reaction to the hardener. The temp of substrate (within reason) bares no relation to its adhesion or ability to cure, that is all hardener and how much or little you use. If you found you needed to heat up your bondo to cure it then you didn’t use enough hardener.
That is true but if the application you are applying the bondo to is cold. It can cause it to peel off or just come off while you’re sanding. Thats what I meant by warmness sorry to have put cure i didn’t mean that. :read:
How cold you talkin here? I am a bodyman and I do body work on cars in the winter where you have to scrape off the snow before doing your bodywork and I have never had an adheision problem.

Must have been the shittiest filler even know it wasn’t reely cheap. But I got pricey filler its more of a green color and i havent had a problem with cure or adhesive ether.
