How about polyester resin and fiberglass cloth? I restore old fiberglass boats, and trust me, doing one surface on a sheet of plywood is fairly easy. Mix the resin with hardener, brush the resin on the sheet, apply the cloth you've already cut to size, squeegee the bubbles out with the brush while making sure resin saturates the cloth, or go high tech and get a stainless steel roller made for such.
I haven't even begun to assemble the stuff I need for a tear drop yet, but am thinking of doing the whole exterior in this manner. For a smooth surface it needs to be sanded, which can be a bear, but for the underneath of the floor, it would provide impermeable surface. Just a thought.
Maybe somebody else has done this too? Or maybe it's not a good idea? Any suggestions appreciated!
