When safety, smell, and paintability are important, use Anti-Rust. It leaves no visible residue and will not interfere when painting treated metal. Anti-Rust is recommended for use in all applications where metal parts are cleaned, exposing them to oxidation (rusting).Anti-Rust mixes readily with water for fast, easy application in spray or immersion rinse procedures. It contains no oils or silicone and dries to an invisible protective film.
