Metal Guard 511 is the result of the latest advances in thin film rust preventive technology. It is a solvent-based, polar water-displacing rust preventive which can be applied by dipping, spraying, or brushing and is designed to be the final finish on an engineered black oxide coating where 80 to 200 hours of salt spray resistance is desired yet dimensional change cannot be tolerated.
Metal Guard 511 meets Mil-C-16173D Grade 3 Specifications for water displacement and meets Mil Spec MIL-C-23411 and MIL-C-81309 for corrosion testing.
Metal Guard 511 is also used for protection against rust and corrosion on automobile parts and accessories, sewing machines, firearms, fasteners of all types, small gasoline engines, machine tools, dies, jigs, fixtures, and metal stampings.
