Talking about expoxy have built several wood kayaks expoxy is highly recommended for use in that when you coat both sides of the pieces it encapsulate them to moister, water doesn't technically rot wood by that I mean standing water ,water vapor penetrates wood and causes wood rot expoxy is or was about $55.00 a gal plus hazmat fee to ship mix a little wood flour in it you could actually glue wood strips together expoxy is also more impact resistant and flexible over that other stuff we do not mention on this forum
