Tetra Gun products have been developed to enhance the life, appearance and performance of fine firearms, sporting classics, knives and collectibles. A surface treated with Tetra is also resistant to rust and rot as Tetra particles provide an effective barrier to the elements. Tetra Gun can only be removed by abrading the treated surface. Tetra Gun is also effective over a broad range, an incredible -100 1/4F to + 750 1/4F! One drop of Tetra Gun contains millions of microscopic lubricant particles which fill and electrostatically bond to the pores found in the metal firearm surfaces, thereby reducing fouling, increasing accuracy, and increasing ammunition velocity.
