Fluid Film Black is a penetrant and lubricant also used for corrosion prevention. More recently they have been introduced and successfully utilized in the automotive and snow handling industries as vehicle undercoating. The wet barrier creeps and migrates into tight seams and into the metal chassis to provide corrosion protection from salts and brines. The addition of Fluid Film Black allows customers to protect their vehicle while restoring a rich black color to the chassis or covering existing rust. Fluid Film Black is Premier Rust and Corrosion Protection, Active Lubricant, Penetrant and Release Agent, formulated from specially processed wool wax, highly refined petroleum oils, and selected agents to provide corrosion control, penetration, metal wetting, and water displacement. The long-lasting product is unique because it contains no solvents, will not dry out and will penetrate to the base of all metals, providing corrosion protection from both natural and industrial atmospheres. Fluid Film Black Penetrants heavily corroded and/or frozen parts such as nuts, bolts, shafts, zippers, etc. that would normally be damaged during maintenance, can be salvaged by applying regular Fluid Film Or Fluid Film Black.
