Theoretically, you could take any substance that will soak into fiberglass and become hard as your resin. Obviously, you want something waterproof and with fairly good strength characteristics.

He is probably best off using some other construction technique all together. There was a time canoes and surfboards were made w/o epoxy of polyester.
