Cold bluing

[a_finelli]

I'm thinking of restoring the finish on an old rifle this winter since I'll. Be getting a new rifle by next session. Is there a product you recommend more than another? Birchwood casey? Brownells? Some other brand? Thanks for the help, Anthony

Check the link. This is a great comparison of several types of cold bluing products.

Whichever product you get, the way I do it is rub in the blue and then rub oil into the surface with your hands. Finally, take a towel and rub the surface with it. I have gotten amazing results doing it that way.

I've done a few old single barrel shotguns with Birchwood Casey cold blue and got some surprisingly good results. Key is prep prep prep ( polishing) then degrease with acetone 2 or 3 times. Then apply bluing in 3 applications, washing, drying and degreasing parts between applications. Lastly wash parts again to stop chem reaction and buff out with 0000 steel wool and oil. even a fingerprint will screw it up so getting the steel free from all oil is important.

The winner of the test in post #2 is Nu Blue and it works well.

After through decreasing, warming the steel with a heat gun, or blow dryer seems to make the cold bluing process work better. It doesn't need to be hot.

I've had very good results with Brownells Oxpho-Blue

I agree with TAC, warming the steel makes a big difference. Seems to make it blue faster, and probably deeper, because when I did heat the parts the cold blueing lasted a lot longer and looked better.

The nice thing about the Brownells Oxpho-Blue is you can build up the depth of the blue. Multiple coats will deepen the quality of the blue.

Have a couple to re-do, interesting thread. Following this subject in the past, it seemed that rust blue would be the way to go. How do the guns hold up with the cold blue that some recommend. Cold bluing would seem to be easier. Roughly, how many coats will do a gun nicely. How do you degrease the guns? Larry
