FLUID FILM BLACK® is an anti-corrosive used for rust and corrosion prevention. It is a non-toxic, long lasting, thixotropic liquid.  Ideal for vehicle undercoating, the non-drying 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 colour to the chassis or to cover existing surface rust whilst providing protection from further deterioration. Not only does it look great, but it’s easy to see where you’ve applied it. The back tint helps to visually ensure even coverage.

FLUID FILM BLACK® is 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 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

If applied to the undercarriage of a vehicle, it ideally needs to be reapplied once per year, preferably in spring as heat helps the fluid film flow better. Depending on environmental factors and where vehicle is used this time frame will vary.

If applied inside of doors and in panels, it will last almost indefinitely. Apply inside chassis frame holes and above metal components where salt and moisture can hide. Then apply a coating to the structural frame and suspension components.  This includes the frame, drive shaft, axles, floor pans, and suspension components (avoid exhaust components and brakes). Only a thin coat of FLUID FILM BLACK® needs to be applied.

As fluid film is based on a natural product it will break down with detergents and high pressure steam. We simply recommend using a low pressure hose to wash under the vehicle.

Fluid Film Black® is compatible with the original Fluid Film and can be used in conjunction with each other. Fluid Film Black® can be applied over existing areas previously treated with the original Fluid Film® coating.
