My friend had a disaster .22 Savage semi-auto, left in a cellar to rust. Was gramps and he wanted to keep it. Normally, I would have stripped the metal and rust and polished the barrel and attempt a cold blue. Cold Bluing has always been marginal for me even when following directions to a T.
After scouring the web I combined a bunch of tips and it worked fairly well. I removed the rust leaving the old bluing on. Then reblued over the old blue.
Rust Removal:
*I soaked in ATF, kerosene and 1/2 ounce of oil of wintergreen, in a PVC Pipe with caps on the end for several days
*I used oil of wintergreen (wear gloves and mask as it is absorbed through the skin) with 0000 steel wool.
Bluing:
*Wore nitrile gloves and continualy rinsed them in the alcohol
*Soaked the barrel in 99% alcohol for a couple hours
*wiped the barrel down with acetone
*Heated the barrel with a torch to just past "warm"
*Applied the bluing
*Hit the bluing with the torch after it dried 5 minutes, and apply more bluing
*Repeated this 6 times, hit it with the torch and doused it in liquid wrench penetrating oil
*wiped it down with gun oil
Of note:
*The barrel was 75 % rust specked with two bad corrosion areas through the blu, came out OK for not polishng the barrel
*I used the cheap Bichwood Casey as I was too impatient for my Brownell's order to get here
*No rinsing between applications
*I polished with Steel wool before the second application of heating and bluing, but the blue seemed to build up/hold up better if I hit it with a torch without polishing
*I think the "torched no rinse/polish" approach may work on a polished barrel, and but I am excited to try it for difficult touch ups.
*I have pics, but how do you enter them from your computer?
