Overview

This shop kit is designed for applying a durable manganese phosphate finish to handguns, rifles, and shotguns, making it a practical option for firearms that need a subdued, service-style appearance. The dull gray coating is intended to blend with camouflage gear and, according to the product description, its porous surface can hold oil to help support rust prevention. It is also presented as a straightforward process for a blasted surface, which can reduce the need for polishing equipment and the time associated with polishing work. Color can vary from light to dark gray depending on the base metal, so the final appearance will not be identical from one firearm to another.

Considerations & Trade-offs

  • The finish color can vary from light to dark gray depending on the base metal’s alloy and hardness, so results are not uniform across all firearms.
  • Parkerizing works best on a blasted surface, which means this kit is geared toward shop setups that can prepare the metal accordingly.
  • The kit is intended for a durable, economical finish, but it is not a polished or decorative finish.
  • The porous coating is designed to soak up oil, so it typically benefits from post-treatment and regular oiling for rust prevention.
