Frequently Asked Questions
Can Perma Blue be used on stainless steel or aluminum?
No — Perma Blue Liquid is designed specifically for carbon steel and blued steel surfaces. It will not produce a proper finish on stainless steel, aluminum, or other non-ferrous metals. For best results, ensure the metal is clean, degreased, and free of any existing finish or rust before application.
How many coats does it take to get a deep, even finish?
Most users achieve a satisfactory finish with 3 to 5 light applications, allowing the solution to work for 30–60 seconds per coat before wiping and neutralizing with oil. Layering thin coats and buffing lightly between applications with steel wool (0000 grade) is the recommended technique for building a uniform, professional-looking blue-black finish.
Is this kit a good long-term corrosion protector?
Cold bluing provides moderate corrosion resistance compared to hot tank bluing, making it excellent for cosmetic restoration and light protection. For maximum durability and rust resistance — especially on working firearms exposed to moisture or heavy use — it's recommended to regularly apply a protective gun oil over the blued surface to extend the finish's life and enhance corrosion protection.
