#3400 Chassis Black Frame Paint is a fast drying, non-pigmented asphalt coating that protects against rust and corrosion.  It forms a dampproof film to keep moisture from getting to the metal.  It is acid- and alkali-resistant which makes it excellent protection against salt brine, cinders, and other corrosive substances.  Use on pipes, storage tanks, machinery, and wrought iron fire escapes.  Dries in approximately 30 minutes.
