Perma Blue vs Super Blue: A Comprehensive Comparison

When it comes to firearm maintenance and restoration, the choice of bluing solution can make a significant difference in the final appearance and protection of the metal. Two popular options in the market are Birchwood Casey's Perma Blue and Super Blue. Both products have their own set of advantages and applications, but which one is right for you? Let's delve into the differences and similarities between these two bluing solutions based on insights from various firearm enthusiasts and forums.

1. Composition and Application:

  • Perma Blue: This is a cold bluing solution, which means it doesn't require any heating during the application process. It's ideal for touch-ups and minor restorations. However, some users have noted that it might streak, especially on polished surfaces, and may require multiple applications to achieve a uniform finish.

  • Super Blue: Also a cold bluing solution, Super Blue is considered to be a bit more aggressive than Perma Blue. It's known for providing a darker and more consistent finish. However, like Perma Blue, the final result can depend on the preparation of the metal and the application technique.

2. Durability:

While both solutions offer a protective layer against rust and enhance the appearance of the firearm, neither is as durable as hot bluing. Cold blue solutions, in general, are more for cosmetic touch-ups and minor restorations. For a more durable and long-lasting finish, hot bluing or other professional methods are recommended.

3. Recommendations:

  • Preparation is Key: Regardless of whether you choose Perma Blue or Super Blue, the final result heavily depends on how well the metal is prepared. Degreasing and cleaning the surface thoroughly can make a significant difference.

  • Application Technique: Using a Q-tip or a small paintbrush can help in applying the solution evenly. It's also essential to wipe off excess solution and apply gun oil afterward to protect the finish.

  • Multiple Applications: Especially with Perma Blue, you might need to apply the solution multiple times to achieve a consistent finish.


Both Perma Blue and Super Blue have their merits. Your choice should depend on the specific requirements of your project and the finish you desire. Remember, while these solutions are excellent for touch-ups and minor restorations, for a more durable finish, you might want to explore other methods like hot bluing. Always prioritize safety and follow the manufacturer's instructions when using these products.
