Krud Kutter® The Must for Rust is a unique rust remover and inhibitor. It removes and prevents rust in one step and can be applied by brush, dip, roller or spray. It also etches new galvanized metal.
The proprietary water-base formula penetrates into voids on the metal surface and dissolves rust and oxidation through chemical action. Small rust-inhibiting crystals are formed and become integral with the surface molecules of the metal to resist future rusting. However, for the best, long-lasting protection we would suggest applying paint or clear coat to help protect the surface for longer.
