This is my full guide to the bluing process
1. Sanding, sanding, sanding, going from grid (400), 600, 800, 1000, (1200) (Be careful not to do too much low grit sanding or you will remove the stampings!!!)
2. Finished sanding process with Liberon steel wool grade 0000. Put some effort into this phase, the smoother the surface, the better the bluing fluid adheres.
3. One thing I learned at this stage: Whatever you do, DO NOT TOUCH the receiver from this point on with anything else than clean paper towels!! Not even with the nitrile gloves. Even the tiniest stains will effect the final result.
4. Clean the receiver with acetone.
5. Rub receiver with clean and dry paper towels.
6. Apply Birchwood Casey Perma Blue (concentrated liquid) with cotton pads evenly and quickly all over the receiver (long strokes). Change cotton pad if you have more than one go.
7. Immediately thereafter rub the receiver with clean and dry paper towels.
8. If you get smudges (you will!), rub the smudges with cotton pads (with bluing fluid on), then immediately thereafter rub off the bluing fluid with a paper towel. Repeat this stage till you get an even finish. Change cotton pad by each go.
9. Seal the parts in acid free oil (I had them soaking for 3 days).
10. Polish with wax, for instance Renaissance Wax.
11. Buff with polishing cloth (for jewelry).
