Rust Veto® 377-HF actually raises water off wet metal to coat the entire surface with a long-lasting film. The polar attraction for metal makes this preventive "creep" across the metal's surface, spreading over a large area. One gallon covers 1,300 square feet. The affinity for metal means handling won't wipe it off. Rust Veto 377-HF contains an antioxidant to resist breakdown and varnish formation, even in long-term storage.
