Frequently Asked Questions
How do I apply Birchwood Casey Super Blue for the best results?
Clean the metal surface thoroughly to remove all oil, grease, and oxidation before application. Apply Super Blue with a cotton swab, patch, or soft cloth in thin, even strokes. Allow each coat to set for 30–60 seconds, then card the surface lightly with 0000 steel wool between coats. Repeat until you achieve the desired depth of color, then neutralize with water and apply a protective gun oil finish.
Will Super Blue work on stainless steel or aluminum parts?
Birchwood Casey Super Blue is designed specifically for carbon steel, polished steel, and hardened steels containing nickel and chrome alloys. It will not blue stainless steel or aluminum, as those metals lack the necessary iron content to react with the bluing chemicals. For stainless, consider Birchwood Casey Aluminum Black or Stainless Steel Black depending on the metal type.
Is cold bluing as durable as hot bluing?
Cold bluing, including Super Blue, provides excellent cosmetic results and moderate corrosion resistance, making it ideal for touch-ups and spot repairs. However, hot bluing — a process done in a professional shop using heated salt tanks — generally offers a thicker, more durable finish for high-wear areas. Super Blue is best used for restoring appearance and providing a protective base coat that is then sealed with a quality gun oil or wax for added longevity.
