Epoxy Ding Stick
The Epoxy Stick is a hand-kneadable epoxy putty that mixes in a minute for making temporary or permanent repairs to any board, dry or wet. It contains a fading blue dye that becomes fiberglass white after mixing.
Works in fresh and salt water, and will bond to fiberglass, epoxy, wood, glass and metal. Doesn't yellow when exposed to sunlight. Cures in thirty minutes!
