Years ago I wet sanded the side of the boat that faced the sun, this year I wanted to wet sand the other side because it was very wet sandable for me. I took this product in hopes that it would help me get to the point where I don't need to wet the sand too deeply. It blew my mind to bring my gelcoat back to life in one fell swoop! I hit some of the trickier areas a second time, but completely missed the need for wet sanding. Hopefully I can keep up with the wax from now on and not get that bad.
