Rust Converter converts rust on any thing made of ferrous metals. It is a water thin liquid metal treatment compound which when applied to rusted metal, chemically changes the rust (iron oxide) into iron phosphate. The surface produced is an inert, hard and grayish, which will serve as a firm base for paint.
On non-ferrous metals, aluminum and galvanized iron, Rust Converter can also be used. It produces a toothed, slightly porous surface to which paint will grip and cling, forming a tight, lasting bond.
