The Birchwood Casey Perma Blue Paste Gun Blue Kit restores the blued finish on worn or scratched steel firearms without the need for hot tank bluing. This cold blue paste formula penetrates deeper than liquid blues, producing a durable blue-black finish that resists wear and helps prevent rust on bare steel. Ideal for touch-ups on carry guns, hunting rifles, or refinishing projects where professional hot bluing isn't practical.
The kit includes Perma Blue paste, Cleaner Degreaser to prepare the metal surface, and Sheath rust preventative to seal the finish. Works on all steel surfaces—not recommended for stainless steel or aluminum. Apply with a clean cloth, let set, then neutralize and oil. Multiple applications build a darker, more even finish.
