I am overhauling my Lowe. The transom fell victim to electrolysis. I cleaned out all the spots and plan on filling them with epoxy filler (see photo). I had heard about this two part epoxy paint but can't find the name now. It is a two part mix. Part of the mix has a crystal in it. Suppose to fill in and seal tiny holes and such. Also is very rugged and flexible. Anyone hear of something like this?
