Birchwood Casey Perma Blue Paste 2oz Gun Bluing Compound 13322

The Birchwood Casey Perma Blue Paste delivers professional-grade cold bluing results for firearms restoration and touch-up work. This selenium dioxide-based formula creates a durable blue-black finish on steel surfaces without requiring heat application or specialized equipment.

What Makes This Different

Unlike liquid bluing solutions that can run and create uneven coverage, this paste formula stays exactly where applied for precise control. The thick consistency allows for targeted application on small areas, scratches, or worn spots while maintaining consistent color depth. Professional gunsmiths choose this paste for its ability to match existing factory finishes on both new and vintage firearms.

Key Features

• 2-ounce tube provides coverage for multiple firearms or extensive restoration work

This cold bluing compound excels in restoration projects where matching original factory finishes is critical. Antique firearm collectors rely on its ability to blend seamlessly with existing bluing on vintage rifles and handguns. The paste formula works effectively on everything from minor scratch touch-ups to complete refinishing of small components like screws, pins, and trigger guards.
