Super Blue gun bluing is a popular choice for restoring or refinishing firearms. This in-depth guide will explore everything you need to know about this chemical bluing process, from its advantages and disadvantages to the step-by-step application. We'll delve into best practices, troubleshooting common problems, and provide tips for achieving professional results. Understanding Super Blue gun bluing will empower you to maintain and enhance the beauty of your firearms.
Understanding the Super Blue Process
Super Blue is a cold bluing solution, meaning it doesn't require heating the metal. This makes it significantly easier and safer to use than hot bluing methods, which demand specialized equipment and a controlled environment. The process relies on a chemical reaction between the bluing solution and the steel of the firearm, creating a layer of iron oxide (rust) that forms a dark blue-black finish. This isn't a truly "permanent" finish like a professionally applied hot-blued finish but is highly durable if applied correctly.
Advantages of Super Blue Gun Bluing:
- Ease of Use: No special equipment or high temperatures are needed. This makes it accessible to home gunsmiths.
- Cost-Effectiveness: Super Blue is relatively inexpensive compared to professional gun bluing services or other types of finishes.
- Safety: The cold bluing process is safer than hot bluing, reducing risks of burns or other accidents.
- Quick Application: The process is faster than traditional hot bluing methods.
Disadvantages of Super Blue Gun Bluing:
- Less Durable: Compared to hot bluing, Super Blue offers a less durable and less corrosion-resistant finish. It can wear off more easily with regular use and handling.
- Less Even Finish: Achieving a perfectly even finish requires careful preparation and application. Imperfections can be more noticeable than with professional hot bluing.
- Not Suitable for All Metals: Super Blue is primarily designed for steel and may not work well on other metals.
- Can Stain Skin and Clothing: Exercise caution and wear protective gear when applying Super Blue.
Preparing for the Bluing Process
Proper preparation is key to achieving a successful Super Blue finish. Careful cleaning and surface preparation significantly impact the final result.
Step 1: Thorough Cleaning
- Remove all grease and oil: Use a solvent like acetone or mineral spirits to thoroughly clean the firearm. Pay close attention to crevices and hard-to-reach areas. A good degreasing agent is crucial.
- Scrub with a brass brush: This helps remove any remaining contaminants and creates a slightly roughened surface, ensuring better adhesion of the bluing solution.
- Rinse thoroughly: Ensure no traces of cleaning solvents remain. Any residue can interfere with the chemical reaction.
Step 2: Surface Preparation
This step ensures a uniform and attractive finish.
- Fine steel wool or scotchbrite pad: Gently abrade the metal surface to remove any imperfections and prepare the surface for the bluing process. Avoid excessive sanding, which can damage the metal.
- Remove any rust or pitting: This is essential for a smooth final finish. Use appropriate tools and methods, depending on the severity of damage. Consult a gunsmith for severe damage.
- Clean the surface once again: Rinse away any debris from the abrasion process.
Applying Super Blue Gun Bluing
The application process is straightforward but requires patience and precision.
Step 1: Apply the Bluing Solution
- Wear gloves: Super Blue can stain skin and clothing.
- Use cotton swabs or lint-free cloths: Apply a thin, even layer of Super Blue to the prepared metal surface. Avoid pooling or excessive buildup.
- Work in small sections: This allows for better control and ensures even application.
- Let it dry: Follow the manufacturer's instructions on drying time.
Step 2: Neutralization (Optional)
Some bluing solutions recommend a neutralizing step after the initial application. This typically involves using a different solution to stop the bluing reaction and prevent further darkening. Follow the manufacturer's specific instructions.
Step 3: Multiple Coats (Typically Needed)
- Multiple thin coats: Super Blue typically requires multiple applications to achieve a deep, even color. Allow each coat to dry completely before applying the next.
- Assess and repeat: Examine the finish after each coat. Apply more coats until you reach the desired level of darkness.
Post-Bluing Care and Maintenance
Once the bluing is complete and dry, proper care and maintenance are vital to prolong its life.
- Oil the metal: Apply a light coat of gun oil to protect the new bluing.
- Avoid abrasive cleaning: Use only non-abrasive cleaning methods to avoid damaging the finish.
- Proper storage: Store the firearm in a dry, clean environment to prevent rust and corrosion.
Troubleshooting Common Problems
- Uneven Color: This is usually due to improper cleaning or application. Re-clean, re-prepare the surface, and reapply Super Blue carefully.
- Streaks or Splotches: These are often caused by uneven application. Try using smaller sections and thinner coats.
- Too Light a Color: Apply additional coats, allowing each to dry completely.
- Rust: Rust indicates inadequate cleaning or insufficient post-bluing oiling. Clean the rust carefully and re-oil.
Conclusion
Super Blue gun bluing offers a relatively simple and affordable way to restore or refinish firearms. Understanding the process, taking careful steps for preparation and application, and providing proper post-bluing care will lead to a long-lasting and attractive finish. However, remember that it's not a permanent solution, and regular care and maintenance are essential for preserving the finish. For exceptional results or heavily damaged firearms, consider seeking professional assistance.
