Wurth Rust Guard Black has been replaced with Wurth Rust Armour – 893110360 Wurth Rust Armour – Black Wurth Rust Guard is a rust-preventive coating designed for application directly on rusted or seasoned metal surfaces. It dries to a rock hard, non-porous finish that won’t chip, crack, or peel. Wurth Rust Guard will prevent rust from recurring by protecting metal from further exposure to moisture. Wurth Rust Guard is sensitive to sunlight and must be top-coated for prolonged exposure to sunlight. Top-coating not required for areas not exposed to sunlight. Same as Por-15.
