Overall a designed hardy product. A couple of draw backs were that there were no mixing instructions or measuring glasses for adding the hardener to the resin. The resin would not mix through the layers as the instructions suggested and would start to harden as you rolled it to get it to go through. As you placed the layers on they would slide around and the weave of the fiberglass layers would come apart. The rollers would gum up with the fiber glass towards the last two layers to go on. Not a product for the novice person to this type of work.
