Blue Steel BSP500ML Primer, Rust Converter Paint 473Ml

Blue Steel converts rusted surfaces into a hard Dark Blue or Black substrate, which can be coated over. It converts rust to a hard, stable substrate over the rusted areas and forms a primer film that serves as a platform for the topcoat. Blue Steel Rust Converter is a great choice for rusted steelwork because it stops the corrosion process right in its tracks.
