I'm wondering what the best stuff would be to use to fill fiberglass holes like screw holes and maybe some bigger holes about the size of a quarter?

Would resin and hardener be the best to use on the screw holes? Is there some kind of fiberglass filler that is strong that I could use? Kinda like bondo? Would it work on quarter size holes too?

Any help/suggestions are appreciated.

Thanks

Marine Tex or any other good white epoxy will do the screw holes. Can sand it easily and matches white fiberglass pretty well, but you might want to top it off with white gel coat. If the quarter sized holes are deeper than an eighth of an inch or so you should probably build it up up with fiberglass and resin. Smooth the top with Marine Tex.
