Metal Guard 510 HF is designed to be the final finish on an engineered black oxide coating
where 100 hours of salt spray resistance is desired yet dimensional change cannot be
tolerated. It is a solvent–based, water–displacing rust preventive, which can be applied by
dipping, spraying or brushing and will displace moisture on the metal surface, leaving a
continuous film of Metal Guard 510 HF in direct contact with the metal surface.
