I thought I would post my experience with Cold bluing in case anyone is going that route.
I had great results with the following steps.
1. Strip bluing by letting parts sit in white vinegar for about 5 hours. Let rinse with water and 0000 steel wool.
2. Remove major pitting and begin polish process by starting with 220 sandpaper followed by 400 then 600.
3. Polish to mirror finish using Mother's metal polish and 0000 steel wool.
4. Remove all polish with a clean rag.
5. Degrease parts with a sponge and full strength Simple Green. Rinse.
6. Rinse again with boiling water. (My revolver I put in a pan of boiling water...my muzzleloader barrel I used a tea kettle and poured the boiling water on it.)
7. Right after the part has been rinsed with boiling water, apply Birchwood Casey Super Black using Q-tips. (Make sure the part is hot but do NOT touch the metal after is has been rinsed)
8. Allow the blue to rust for about a minute. Then either boil the part or pour boiling water on it. The blue should start to turn grey/white.
9. Lightly card off rust with 0000 steel wool (make sure the steel wool has been degreased as well...I just used a simple green bath)
10. Rinse with boiling water or boil part again.
11. Repeat 7-10 for about 5 coats total.
12. After step 11, now it is time to replace Birchwood Casey Super Black with BC Perma Blue paste. Repeat 7-10 with the paste for about 2-3 coats.
13. Final rinse with boiling water. (The water should bead up instead of run off...that's when she is done) Then wipe dry with clean paper towel.
14. Apply gun oil (from bottle not spray can) and generously coat. Let sit for 24 hours.
15. About every month I apply a light coat of oil to the parts that were blued and store in my safe with closet dehumidifier right next to it.
This process worked well for me. Grease is the biggest enemy to this process.
