I've got scrapes along the keel and a couple other areas of the hull where the gel-coat has been scraped away and I can see fiberglass fibers (see pix). I've sanded the areas down and a boat repair guy told me to just put a few coats of fiberglass resin over them. However, I've been reading and seen comments about bondo fiberglass resin (polyester?) not being good for below the waterline, and that I should use epoxy instead. But then I read that you cant put gelcoat over epoxy, and that gelcoat will only go over a polyester resin (such as bondo fiberglass resin?). Now that I've read more, Im confused... Reading more isnt really helping at this point.
What should I use to fill over the gouges, epoxy or fiberglass resin? Can anyone tell me a brand and product name for whichever it is? Something I can get at a marine supply/parts place or hardware store, and dont have to order and ship, if possible. Either way, do I need to put gelcoat over it? If so, what's a good product to use (Im not too worried about color matching). I dont really care about the cosmetic appearance of the keel and this ridge, but I want everything to be structurally sound. If gelcoat isnt needed and I only need one product on the hull, that's what I want, as long as Im not messing with the integrity of the hull...
Also, are the stress cracks on the transom in the picture I included an immediate problem?
