I have a leak in my boat and upon inspection saw these damaged rivets in the keel. what would be the easiest, best way to fix this? aluminum boat repair: tig and some oxy acetylene. Diy aluminum boat rivet repair is very easy with hts-735-11 fluxless aluminum brazing rod from aluminum-weld.com.. Re: keel repair on a aluminum boat do not weld!(and this is coming from a weldor that fixes alum. boats) use s.s. truss head phillips screws with flat washer and nylon locking nut on the back side..
