Re: fiberglass keel repair- Help!
Rather difficult to see the pictures, but I would grind back to find some good glass. If you have deep gouges sand out to have a wider circle, so the epoxy will stick better. Put in some epoxy putty to the holes/gouges. Then put on a layer of 1708. Might want to check out West System's website they have some good information on fixing a keel. Also there needs to be something more than just epoxy. Epoxy by itself adds no strength and will crack at nothing.
