Fluid Film is a penetrant and lubricant also used for corrosion prevention. The long lasting product contains no solvents, is designed to keep from drying out, and will penetrate to the base of all metals, providing corrosion protection from both natural and industrial atmospheres. Heavily corroded and/or frozen parts such as nuts, bolts, shafts, etc. that would normally be damaged during maintenance, can be salvaged by applying Fluid Film. It has been used for over fifty years in the highly corrosive marine environment of ships and offshore drilling rigs.
