The special formulation leaves behind a microscopic layer of protection against rust and corrosion caused by handling, fingerprints, moisture and harsh environments, including salt water. Used by major firearms manufacturers to coat and protect firearms prior to shipping, the solvent based aerosol contains a unique drying agent that leaves your firearm clean and protected from rust and corrosion without any gummy residue.
