Extend the life of your metal equipment by protecting it from rust and corrosion. Rust occurs naturally when the iron in steel oxidizes and returns to its original state, iron oxide. Through an innovative chemical conversion process, Corroseal Rust Converter converts rust (iron oxide) into a stable substance, magnetite. It also primes the surface with a high quality latex metal primer at the same time. Corroseal truly provides one step corrosion control.
