Frequently Asked Questions

What is gun bluing and why is it used?

Gun bluing is a protective finish for firearm metal that prevents rust. It works by creating a controlled, 'benevolent rust' layer to inhibit destructive red rust and pitting, preserving the firearm's metal components.

How do you prepare metal for Birchwood Casey Perma Blue Paste application?

Before applying bluing paste, ensure the metal is rust-free. Thoroughly clean all oil from surfaces using isopropyl alcohol, then lightly abrade the metal with an abrasive cloth or steel wool for optimal adhesion.

What is the advantage of using bluing paste over liquid bluing?

Bluing paste, like Birchwood Casey's formula, is preferred because it allows for precise manipulation and prevents the product from running. This makes the application process much cleaner and more controlled.

How do you achieve a darker finish with Perma Blue Paste?

To achieve a darker finish, repeat the application of Perma Blue Paste. After each coat, wipe off excess paste, rinse with fresh water, burnish with steel wool, and clean the surface again before applying the next layer.
