A very user-friendly process that produces a non-metallic zinc phosphate coating on iron and steel that is highly resistant to corrosion, very durable and long wearing. The traditional, charcoal-gray color is ideal for non-glare finishes on tactical and hunting guns, or restoring older military guns. The large, uniform grain structure and even thickness coating gives excellent retention for lubricants and rust preventives. Also provides an ideal base for spray-on/bake on finishes such as Brownells Baking Lacquer, Aluma-Hyde II and Teflon Moly Gun Finish. The porous surface produced by Zinc Phosphate Parkerizing actually bonds the final finish to the gun for a durable, long wearing coating. A very clean process, Zinc Phosphate leaves almost no sludge buildup around the heating coils in your tank. If you are already setup for parkerizing, switching to Zinc Phosphate is a simple matter of changing chemicals in your tank. SPECS: Net Contents: 1 gallon (3.8L), 1 pint (473ml).
