Super Blue is the heavy hitter in Birchwood Casey's cold blue lineup. It's a double-strength solution made for rebluing highly polished steel and hardened steels that contain nickel or chrome alloys, and it lays down the darkest, richest blue-black of any of their extra-strength formulas. Since it's a cold blue, there's no torch, no boiling tank, and no special equipment required to get a real finish on your metal, which is exactly why it's a shop staple for touch-ups and small refinishing jobs.
This formula is aimed at high-strength alloy steels rather than soft low-carbon stuff, so it earns its keep on receivers, barrels, and hardened parts where a weaker blue would struggle. It reacts quicker than blue paste and gets you there in fewer coats, and you can apply it with a swab, cotton pad, or a small paintbrush depending on the size of the area. One thing to keep in mind: it's not for stainless steel, and you'll want to keep the solution confined to the exact spot you're working since it will darken any existing blue it touches.
With cold blue, prep is everything. Strip the old finish and any oil down to bare, clean metal using steel wool or fine abrasive and a good degreaser like denatured alcohol. Warm metal takes the blue better than cold metal, so a lot of folks give the part a little heat with a hair dryer or hot water before application. Wipe on the solution, let it dwell, rinse and neutralize with water, then card the surface with 0000 steel wool. Repeat the process a few times to build the depth of color you're after, then seal it with a coat of gun oil to protect the finish.
The 3 oz plastic bottle is sized right for gunsmithing and hobby work, and it's plenty for scratches, worn spots, or bringing an older piece back to life. It's a proven touch-up and refinishing solution that's been in gunsmith drawers for decades.
No, Super Blue is not made for stainless steel and won't take on it. It's formulated for highly polished steel parts and hardened steels containing nickel and chrome alloys. For stainless work you'll need a product specifically designed for that metal.
Super Blue is a double-strength formula aimed at high-strength alloy steels and hardened parts, and it produces the darkest blue-black in Birchwood Casey's cold blue lineup. Perma Blue is geared more toward low-carbon steels. If you're working on softer low-carbon metal, Perma Blue is often the better match, while Super Blue shines on tougher alloys.
Clean prep is the biggest factor. Strip the metal down to bare, oil-free steel with steel wool and a degreaser, warm the part slightly since warm metal blues better than cold, then wipe on the solution and let it react. Rinse, neutralize with water, card with 0000 steel wool, and repeat the coats until you reach the depth of color you want before sealing it with gun oil.
It handles both. It's excellent for touching up scratches and worn spots, and with proper prep and repeated coats it can bring an older piece back to a deep, even finish. Keep in mind that any cold blue is a touch-up and refinishing tool at heart, so for a factory-grade full reblue on a valuable gun, many folks still prefer professional hot bluing.
