I am working on a Tuff Weave Wenonah canoe that has some minor hull damage where several small chunks of the paint/gel have cracked and brocken away from the fiberglass material. Most are 1x1 inch sizes of damage. I bought some of this JB WaterWeld epoxy putty and think I might give it a try for filling in the repairs. It says its first recommended use is on fiberglass boats! Looks like some really good stuff. Anybody have experience with it?
