Two ounces of clear, high strength, fiber reinforced epoxy resin repair putty mixture. To fix your board, you simply cut away any loose foam and fiberglass and squeeze in the clear gel roughly replacing the void. It"s called "Solarez" because it cures (dries and hardens) when sunlight is introduced, so you can basically work on your project in the garage and then walk it outside to cure the whole process in under 5 minutes. Once it dries, you can just sand it down to the original shape of your board. The result is a 100% waterproof repair, and you"re safe to take your board back in the water.
