I started a thread a little while back about fixing a crack in the keel of a river hawk. Well I finally removed the front bench seat and too my surprise, the false floor stopped on each side of the bench. So luckily I have easy access to the crack from the inside out. For this repair I looked at the uscomposites website. Should I order the 635 thin epoxy resin with medium hardner, and 7 1/2 oz e glass fiberglass cloth? I want the repair to be as strong as possible. Thanks.
