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. 11.75 ounces.
