Therefore, the Cerakote C-7700Q, a low-cost material that can be applied with a pressurized spray gun at about 30 psi, was ultimately chosen as the only candidate coating material for further testing and assessment.

Conclusion All coating process are designed to protect your cherished firearm from the elements at all times: in the field,at your side, or in the trunk of your vehicle. Because a firearm often represents an investment, you will want to be sure that yours receives the best treatment possible to ensure many trouble-free hours of shooting.

For further information, read on and learn about six different gun part coating options: bluing, Parkerizing, anodizing, Cerakote, nickel boron and ferritic nitrocarburizing. Gun Bluing (Black Oxide) Steel bluing, also known as gun bluing, oxidizing and black passivating, is a process by which the metal is given a rust-resistant finish.

Gun Anodizing
Gun Anodizing

Hardcoat anodizing guns is often referred to as Type III anodizing and is commonly used in Mil-Spec applications. This type of metal coating is formed by the application of an electrolyte solution of sulfuric acid at a temperature of approximately 32 degrees Fahrenheit.

I work with coloring metals in tangent applications. In my experience in bluing gun parts I can offer a few observations. Surface prep. and cleaning are very important. Get some 0000 or 000 steel wool and clean with alcohol after rub downs. Wash with clean water. The Oxide builds up to saturation, regardless of further applications.

Nickel Boron Coating for Guns
Nickel Boron Coating for Guns

NP3 has great corrosion resistance twice the amount of nickel boron. NP3 Plus has ten times the corrosion resistance of nickel boron. Nickel boron is at the same level of corrosion resistance as regular nickel or chrome (Nickel Boron Glock with Corrosion) Share this blog post on Facebook, Twitter, and in forums.

Parkerizing for Guns (Phosphating)
Parkerizing for Guns (Phosphating)

Parkerizing is usually considered to be an improved zinc or manganese phosphating process, and not to be an improved iron phosphating process, although some use the term parkerizing as a generic term for applying phosphating (or phosphatizing) coatings that does include the iron phosphating process. Parkerizing is commonly used on firearms as a more effective alternative to bluing, which is an earlier-developed chemical conversion coating.
