epoxy is AWESOME. It makes boat building easy. If your peices of wood arn't quite the right size and theres a gap, it doesn't matter. you can thicken the epoxy and fill the gap. you can make the outside of something really durable by reinforcing it with fiberglass, or use it as a glue, by mixing in a power to thicken it. you can buy special powders to do this, but I just use flour. you can thin it down so it soaks into wood, sealing it and protecting it from water - and hardening the surface.
