I saw Rust-Oleum NeverWet on the local news and had to try it out myself. I picked it up at Home Depot for $18.75. It is a two part application, a base coat and a top coat. I tested it out on a scrap piece of wood and it worked out great. I then went ahead and applied it on my shower curtain to prevent the gross mold from forming at the bottom of the shower curtain, and it kinda worked. I don’t think I applied a even coat. It was hard to see where I had, or had not sprayed the product. May sure you apply a good solid coat of the base and top coats.
