Ok So I Am Ready To Install My Floor In The Boat. What Should I Seal The Plywood With? Should I Use Something Like A Thompsons Water Seal Or Something Else?
Coat the bottom side of your floor with fiberglass resin and a weenie roller.
2 coats would be advisable. Be double sure to get about 3 or 4 coats on all edges, as the edges will soak up a lot of resin.
