Phosphating/ parkerizing

We do not recommend this finish as a primary finish due to its poor corrosion resistance and wear. We do not cover this finish in our lifetime warrantys Phosphating, better known as “Parkerizing”, is a process involving the transformation of the surface of the steel to a rust resistant manganese or zinc phosphate. Modern chemicals for phosphating are far superior to their predecessors. Phosphating is a non-reflective, matte black finish that resists corrosion and abrasion. The coating has a sponge-like structure that entraps oil or other corrosion resistant solutions producing an excellent coating for firearms exposed to high humidity and/or harsh environments. Phosphating will hide light scratches, pitting or blemishes. Coating thickness of the finish varies depending on the user requirement. Phosphate coating applied by Robar® will meet the following requirements: DOD-P-16232 F, Type M Class 1, 2 & 3 and Mil-P-50002 A Type 1, Composition B. DOD-P16232 F Type Z Class 1, 2 & 3
