This guide details a technique for applying cold bluing solution, as demonstrated by Steve from Brownells. It covers essential steps from surface preparation and contamination prevention to application methods using steel wool and neutralizing the finish. The advice emphasizes understanding steel types and the importance of proper oil removal for effective bluing.

Quick Summary

To effectively apply cold bluing, thoroughly clean the metal with rubbing alcohol to remove oils. Pour solution into a separate cap to prevent bottle contamination. Warming the steel can speed up the reaction. Use 0000 steel wool for application and burnishing. Neutralize with water post-application and finish with oil.

Frequently Asked Questions

What is the most important step before applying cold bluing solution?

The most crucial step is thorough surface preparation. You must clean the firearm's metal meticulously with rubbing alcohol to remove all oils and contaminants, ensuring the bluing solution can properly react with the steel for an even finish.

How can I prevent contaminating my cold bluing solution?

Never dip your applicator directly back into the original bottle. Instead, pour a small amount of the solution into a separate container like a plastic cap. This prevents the entire bottle from becoming contaminated with oils or debris from the firearm surface.

Can I speed up the cold bluing process?

Yes, warming the steel surface, for example, by using hot water, can help accelerate the chemical reaction of the cold bluing solution. This often leads to achieving the desired color more quickly and effectively.

What should I do after applying cold bluing to my firearm?

Once you achieve the desired color, it's essential to neutralize the bluing process by wiping the treated area with water. This stops the chemical reaction and prevents 'after-rust.' Finally, apply a coat of gun oil for protection.
