SurfTech Ding Dough is a quick fix, easy to use, fiberglass reinforced "dough-like" compound that is designed to cure in or out of the water! It's perfect for travel or at-home repairs it can be used with Epoxy or Polyester boards and can also be used as a filler for more thorough repairs. Just pinch it, knead it, smooth it on the board and you're back on the water!
Works well, solid and waterproof. Is pretty thick though so can be hard to work into small cracks. I cut my board open farther around the damaged bits to be able to get the epoxy in there.
Great Stuff! Repaired a crack in my surftech board in 30 minutes....good as new! A+
