WEICON Rust Converter neutralizes rust on rusty cast iron and steel surfaces. Rust onverter reliably stops the corrosion process and thus provides a base coat for ubsequent surface coatings. Due to its special formula, Rust Converter penetrates rust and, in a chemical process, converts iron oxides into a stable black layer. Rust Converter can be applied on all rusty areas, e.g. on machines or in plants, on agricultural equipment as well as motor vehicles.
