DRY COAT™ Rust Preventative

Rust Prevention with Invisible Protection, Visible Results

Wash your hands (both literally and figuratively) of hazardous solvents and messy oil-based rust preventatives with ARMOR Dry Coat™ and Dry Coat™ ST Rust Preventative. Dry Coat is water-based and designed for use on ferrous metals. It is your clean, safe and easy way to say “bye bye” to the dirty and time consuming rust prevention methods of days gone by.

When we say Dry Coat offers “Invisible Protection, Visible Results” we mean it. Once applied to the surface of metal, Dry Coat dries-to-touch within minutes (in ambient conditions) leaving a clear, protective coating that repels water and other rust-causing substances. Dry Coat is not sticky or tacky; it does not attract dirt or dust; it does not interfere with stamping, grinding, cutting, welding; and it is easy to remove if needed.

Dry Coat is offered in two formulations — original Dry Coat that protects metal parts stored indoors for up to one year and Dry Coat ST for the short-term protection of metal parts stored indoors for up to 3 months.
