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.
