Fluid Film is a lanolin based rust/corrosion preventive and lubricant that provides long term protection and lubrication for all metal surfaces. Fluid Film contains no solvents. It will not evaporate, get gummy or tacky, freeze or burn greenery. Fluid Film locks out and displaces moisture and effectively stops corrosion from salts, fertilizers and herbicides. It does not simply wash off with water, but creates a barrier of protection that continues to work even in the most corrosive of environments.
