Birchwood Casey's Aluma Black is a popular gun bluing solution, promising a durable, professional-looking finish at a fraction of the cost of professional gunsmithing. But does it live up to the hype? This comprehensive review delves into the product's features, application process, results, and overall value, offering a detailed analysis for both seasoned gun enthusiasts and newcomers alike.
What is Aluma Black?
Aluma Black is a cold-bluing solution from Birchwood Casey, designed for use on steel, iron, and other ferrous metals. Unlike hot-bluing, which requires specialized equipment and high temperatures, Aluma Black is a cold process, making it significantly easier and safer to apply at home. The solution chemically reacts with the metal to create a black oxide coating, offering corrosion protection and a matte black finish. Its popularity stems from its relative ease of use, affordability, and accessibility.
Advantages of Using Aluma Black
- Ease of Application: The process is straightforward, requiring minimal specialized tools or equipment, making it an ideal choice for DIY gun enthusiasts.
- Cost-Effectiveness: Compared to professional gunsmithing services, Aluma Black offers a significant cost savings.
- Durable Finish: While not as durable as professional hot-bluing, Aluma Black provides a reasonable level of protection against corrosion and wear, especially with proper preparation and application.
- Wide Availability: The product is readily available from numerous sporting goods retailers and online vendors.
The Aluma Black Application Process: A Step-by-Step Guide
The success of Aluma Black hinges on proper preparation. A meticulous approach will yield far superior results.
1. Preparation is Key:
- Cleaning: Thoroughly clean the metal surface to be blued using a degreaser and fine steel wool or a suitable abrasive. Remove any rust, grease, or oil. Imperfect cleaning will lead to an uneven finish.
- Surface Preparation: Depending on the condition of the metal, you may need to use progressively finer grit sandpaper to achieve a smooth, consistent surface.
2. Applying Aluma Black:
- Application Method: Follow the manufacturer's instructions meticulously. Typically, this involves applying several thin coats of the solution, allowing each coat to dry completely before applying the next.
- Even Coating: Use a clean cotton swab or applicator to ensure even coverage. Avoid pooling or thick applications.
3. Neutralization and Finishing:
- Neutralization: Once the final coat is dry (allow ample drying time as specified on the product packaging), neutralize the solution according to the instructions. This step is crucial for achieving a stable and durable finish.
- Oil Treatment: Apply a protective oil, such as gun oil, to help preserve the finish and provide additional corrosion resistance.
Potential Drawbacks and Limitations
- Durability: While Aluma Black offers decent protection, it's not as durable as professional hot-bluing. Expect some wear and tear with regular use.
- Finish Consistency: Achieving a perfectly even, professional-looking finish requires patience and attention to detail. Improper application can lead to uneven color or blotchiness.
- Not for All Metals: Aluma Black is specifically designed for ferrous metals. It will not work on non-ferrous metals such as aluminum or brass.
Conclusion: Is Aluma Black Worth It?
Aluma Black provides a viable and affordable option for those seeking to achieve a matte black finish on their firearms or other ferrous metal projects at home. While it may not match the longevity of professional hot-bluing, the ease of application, cost-effectiveness, and readily available nature make it a popular choice amongst DIY enthusiasts. However, remember that achieving professional-level results necessitates careful preparation, meticulous application, and a keen eye for detail. For those willing to invest the time and effort, Aluma Black delivers a satisfactory finish.
