Clear Guard Spray Environmentally Friendly is a protective lacquer for all metals which guards against sun, mild acids, salts, heat and water. Provides a hard, fast drying and tarnish resistant film. Satin & Matte finish available. The EF formula works well on Blue and Green Patinas, and dries just a little slower compared to the original formula.
