Fluid Film is a lanolin based rust/corrosion preventive and lubricant that provides long term protection and lubrication for all metal surfaces. Fluid Film locks out and displaces moisture while lubricating moving parts for extended periods of time. It will not be readily washed off with water, but creates a barrier of protection that continues to work even in the most corrosive of environments. Fluid Film is the worldwide standard for corrosion protection and lubrication. Both John Deere and Caterpillar use Fluid Film on their heavy equipment before shipment. It sits out in full exposure to salt air, salt water, and rain, and the product continues to provide protection.
