Main Highlights

  • Non-tacky application. With solvent-based materials, the end product ends up being a gummy, sticky mess. Fluid Film will NEVER get tacky, retaining a super-slick consistency that provides excellent lubrication for moving parts on all metals.
  • Eco-Friendly. No solvents means no ozone depleting chemicals contaminating the atmosphere. It is classified as non-toxic and non-hazardous and is safe to be used inside the home, as well as out in the field.
  • Fluid Film is manufactured using an all-natural lanolin base. Lanolin is of animal origins, extracted from the wool of sheep, which use it as a waterproofing wax to aid in shedding water from their coats. It has been used for centuries for its medicinal and rust-preventive properties.
  • The unique molecular structure of Fluid Film creates a non-drying coating that can last at least a year indoors protecting equipment from rust or corrosion, or a full season outside in the elements. Fluid Film is safe to use on all metals, will not freeze, and will not readily wash off a surface.
