Rust-Oleum® NeverWet® is a one-step, superhydrophobic, water repelling treatment designed to keep footwear and other gear dry longer. This crystal-clear formula preserves footwear against damaging moisture without changing the look or feel of the fabric. Coverage varies depending on fabric but expect between 20 and 60 square feet. NeverWet® is a patented covering that deflects nearly all liquids and heavy oils by creating a very high contact angle upon application. The traditional definition of a contact angle is the angle a liquid creates with the solid or liquid when it is deposited on it. The 160 to 170° angle is much higher than traditional substrates, such as car wax (90°), Teflon (95°), or Rain-X (110°).
