Start with the Product Selection Guide to determine which products you need for your specific project. Choose a dispensing pump based on the size of your project, resin-hardener ratio (or your budget). Select one of four hardeners for speed or clarity. Filler selection should be based on the strength for bonding or the sandability you need for fairing. Additives and pigments provide for additional properties such as abrasion resistance and coloration. Reinforcing materials such as fiberglass cloth and carbon tapes should be selected based on where and how you want to enhance structural reinforcement.
