This product, Rust-Oleum NeverWet is truly amazing. After application, all manner of liquids run off the surface of any material without leaving a mark. This spray-on superhydrophobic repels mud, water, ice and all of the other things.
The silicon-based spray coats the material, and hey presto! Your blue suede shoes are eternal as Rob Lowe. After a two year wait the product has finally reached the shelves of Home Depopt stores.
