Presto Blue Mag 3 oz Powder for Reloading and Shooting
Presto® Mag Gun Blue - Birchwood Casey Cold Bluing Solution
The Presto® Mag Gun Blue by Birchwood Casey is an advanced cold bluing formulation engineered specifically for the restoration and enhancement of deep blue finishes on ferrous metal firearm components, excluding stainless steel alloys. This precision chemical treatment is optimized for shooters, gunsmiths, and reloaders seeking to rejuvenate their firearms aesthetic and corrosion resistance without resorting to traditional hot bluing processes.
Key Technical Features:
- Cold Bluing Chemistry: A user-friendly, low-temperature chemical solution that facilitates controlled oxidation of steel surfaces, producing a uniform, durable blue-black finish without the need for specialized thermal equipment.
- Material Compatibility: Formulated to interact effectively with carbon and alloy steels commonly used in firearm barrels, receivers, and magazines, while explicitly excluding stainless steel due to its passivation layer.
- Professional Grade Finish: Delivers a deep, lustrous blue patina that not only enhances visual appeal but also provides a protective barrier against rust and corrosion in field and storage conditions.
Application Protocol:
- Surface Preparation: Meticulously degrease and clean the steel substrate to remove all oils, residues, and contaminants using a dedicated metal cleaner or solvent. Ensure the surface is completely dry to maximize chemical adherence.
- Product Application: Employ a lint-free cotton swab, applicator pad, or microfiber cloth to evenly coat the target area with the Presto® Mag Gun Blue solution, ensuring full coverage for consistent oxidation.
- Reaction Time: Allow the chemical reaction to proceed undisturbed for several minutes, monitoring the development of the blue-black coloration until the desired depth and uniformity are achieved.
- Neutralization Step: Rinse the treated surface thoroughly with cold water to halt the chemical process and remove any residual solution, preventing over-bluing or uneven finish.
- Final Drying and Protection: Dry the firearm components completely using compressed air or a clean cloth, then apply a high-quality firearm oil or rust preventative to seal the finish and enhance long-term durability.
Safety and Handling Precautions:
- Always wear nitrile gloves and operate in a well-ventilated workspace to minimize exposure to chemical vapors.
- Avoid direct contact with skin and eyes; in case of accidental exposure, flush immediately with copious amounts of water and seek medical advice if irritation persists.
- Store the product securely out of reach of children and pets, in accordance with local hazardous material regulations.
Summary: The Presto® Mag Gun Blue cold bluing solution represents a highly effective and accessible method for firearms enthusiasts and reloaders to restore and maintain the classic deep blue finish on steel firearm parts. Its ease of use, combined with professional-grade results, makes it an indispensable product for precision metal finishing and corrosion protection without the complexity and hazards associated with traditional hot bluing techniques.
