There are so many types of ding repair kits out there, things can sometimes get a bit confusing, and its hard to know even where to start. The first thing you should do is figure out whether your board is made with Polyester Resin, or Epoxy Resin. This is important because if you polyester resin on a epoxy board, it will disintegrate the foam. If you are unsure what your board is made with, the safe bet is to buy epoxy resin, as you can repair both polyester and epoxy boards with this resin. Sun cure is great for quick fixes, as is the ding repair putty, which is a great travel accessory.
