Description
The Birchwood Casey Presto Mag Gun Blue is a professional-grade cold blue formulation designed to restore the deep blue-black finish on worn or freshly polished steel firearm parts. Packaged in a convenient 3 oz bottle, this liquid bluing solution penetrates hard steel almost instantly and lays down a durable, blue-black finish that will not rub off with normal handling. No heat is required, making it an ideal at-home and bench solution for touch-ups, re-finishing small parts, and complete re-bluing of all-steel (non-stainless) firearms.
Presto Mag is specifically formulated for users who want a deep, even blue luster on metal surfaces, and it typically produces the desired result with just one coat. The fast-acting chemistry reacts quickly with properly prepared steel, and the liquid is easy to apply with a swab or patch. It is suitable for use on all steel firearms and components, with the exception of stainless steel, which is not reactive to the cold-blue process.
Whether you are refreshing the finish on a vintage hunting rifle, blending a small scratch on a carry pistol, or completing a full restoration project, this 3 oz bottle of Birchwood Casey Presto Mag Gun Blue provides enough material for multiple applications on standard-sized parts. Each order includes one (1) 3 oz bottle of cold blue solution.
