Birchwood Casey Perma Blue Paste Gun Blue Kit BC-13701 Touch-Up Rebluing
Restore worn or scratched bluing on steel gun parts with the Birchwood Casey Perma Blue Paste Kit — a cold-blue formula trusted by gunsmiths, collectors, and shooters since 1948. Applied directly from the paste, it chemically bonds to bare steel to produce a durable blue-black finish without heat, tanks, or special equipment. Works on small touch-ups and larger re-bluing projects alike, and cleans up easily with water.
Key Features
- Fast-Acting Cold-Blue Formula — Reacts with bare steel in seconds; most touch-ups require only 2–3 application passes, letting you return the firearm to service the same day.
- Uniform Blue-Black Finish — Produces an even blue-black color on treated steel that closely matches factory hot-blue and rust-blue finishes, helping touch-ups blend without a visible edge.
- Non-Streak Application — The non-streak paste formula prevents blotchy or uneven results, giving you clean, predictable coverage even on curved or complex metal surfaces.
- Touch-Up and Full Re-Bluing Versatility — Apply with the included steel wool pads for small scratch repairs, or use successive passes across a degreased surface for a full re-blue — no additional tools required.
- Complete Kit — Ready to Use — Includes Perma Blue paste, neutralizing solution, and application pads so you have everything needed to start immediately, with no additional purchases required.
