Gun bluing is a conventional finish applied to firearms. Bluing shields protect the steel from corrosion and gives the metal a very dark blue finish. The manufacturing plant bluing process hasn’t changed much over the years, and gun owners can likewise now purchase home bluing kits to touch up or refinish their firearms.

2. Make ready the parts to be dipped in the cleaning & bluing solutions.
3. In the third step, put the gun parts in a cleaning solution bath.
4. Rinse off a cleaning solution in the cold water.
5. Put the gun parts in the bluing solution.
6. Then, Properly rinse off the bluing solution in cold water.
7. Submerge the gun parts in boiling water.

This bluing is not so effective as a protective covering as hot bluing, but for small restorative touch-ups, it is perfect. For cold bluing, there are a few steps that you need to follow:

6. Season the finish with gun oil once you have the level of bluing you expect.

3. Rust Bluing

Rust bluing was created among hot and cold bluing processes. This is one of the older methods of bluing and provides the best rust and corrosion resistance. The process of rust bluing is normally only for double barrels or very old firearms. In the past, bluing commonly used a chemical containing Cyanide. Cyanide was the active agent that produced the blue/black or blue/gray color.

Today’s new ‘salts’ along with high heat can have an adverse effect on any solder used to fasten the barrels to the rib. Instead, using a ‘rust’ process with lower heat produces a color closer to the old blue/gray color and it does not have the adverse affect on the solder. But, this process is much more labor-intensive, involving up to six or eight applications of the rust bluing process.

There are few steps of rust bluing to bluing gun properly, Let’s have a look.

1. Polish the gun parts to be blued.
2. Clean away any oil, dirt or grease that remains chemically.
3. Coat gunmetal parts with a mixture of hydrochloric & nitric acid.
4. Submerge the gun metal parts in boiling distilled water.
5. Scrub away red oxide rust that has formed, leaving the black oxide finish underneath.
6. Repeat an acid treatment, boiling, & scrubbing until you have achieved the desired level of bluing.
7. Coat all gun parts with oil.

All these bluing types will effectively improve your gun’s resistance to corrosion, and give your gun a unique, vintage-style finish.
