I just finished waterproofing the cabinet bottom about 20 minutes ago. I outlined the area to be waterproofed with 1/4 round molding. Then I laid in a layer of 8oz fiberglass cloth, poured the F/G resin on it and brushed it in with a brush. The 1/4 round is used because F/G does not like to make right angle bends. It will just pull away from the surface as it hardens if you go more than a 45 degree bend. In areas where you can't make that bend, you just lay the glass cloth flat on one surface. Then cut another piece to lat flat on the other then fill the joint with resin.
After about an hour of dry time, I'll go out and trim of the excess cloth with a razor blade. By tomorrow morning that cabinet will be as waterproof as some bathtubs.
You'll notice that I left the outer edge flat so that water can just drain down the side of the camper. Just like the water drains down the roof on your camper.
