Birchwood Casey Perma Blue Liquid Gun Bluing Solution 3 oz Bottle

The Birchwood Casey Perma Blue Liquid delivers professional-grade cold bluing results for firearms restoration and touch-up work. This concentrated formula penetrates metal surfaces to create a durable, corrosion-resistant finish that matches factory bluing.

What Makes This Different

Unlike spray-on bluing products that sit on the surface, Perma Blue Liquid chemically bonds with steel at the molecular level. The liquid application allows precise control over coverage areas, making it ideal for small parts and detailed work. This formula works at room temperature without requiring heat application or special equipment.

Professional gunsmiths rely on this product for restoration projects where matching original factory finishes is critical.
