Cosmoline "Creeper" Coat (alternate trade name: Rust-Veto 377-HF) actually raises water off wet metal to coat the entire surface with a long-lasting, transparent, rust-inhibiting film.  The polar attraction for metal makes Cosmoline "Creeper" Coat 'creep' across the metal's surface, spreading over a large area.....One gallon can cover as much as 1,300 square feet!  The affinity for metal means handling won't wipe it off.  Cosmoline "Creeper" Coat contains an antioxidant additive and will resist breakdown and varnish formation, even in long-term storage.  


  • Provides reliable protection from rust & corrosion (see general protection duration guidelines below)
  • Displaces water, condensation, humidity or process fluids from wet parts to rapidly begin the corrosion inhibition process.
  • Exceptional penetrating characteristics allowing protection in even the smallest of crevices and cavities.
  • Incredibly easy to apply and remove.
  • Great value as 1-gallon can cover up to 1,300 sq./ft.
  • The high flash point reduces the potential for flammability and may reduce fire insurance premiums.
  • Low-odor nature of the products optimizes worker acceptance.
  • Easily removed with mineral spirits, paint thinner, Cosmoline Remover or any other over-the-counter petroleum solvent.
