Metal Guard 900 was developed to provide superior protection on bare metal surfaces for extended in door and outdoor exposures. It is a viscous, solvent-based rust preventative which can be applied by dipping, spraying, or brushing onto the bare surfaces of parts. As the coating dries, a soft water-resistant amorphous coating forms which protects metal surfaces. This coating can be removed with a heated alkaline cleaner, or the bulk can be easily wiped away with the remainder removable with warm soapy water.Â
