I found some old brass parts I had kicking around and after seeing some great examples I thought I'd give polishing a try. Major thanks to ryan hall and the guys over on mcb custom corner for walking me through it.


Sand Paper (600/1200)
Brass Polish (mothers or flitz)
Cleaner Towels
Brass Pneumatics


Rinse your pneumatics with water
Start wet sanding with 600-800 grain sand paper. Wiping off the grime as you go.
After you finish sanding with 600-800 grit sandpaper, start wet sanding with 1200 grain paper.
After you are finished sanding with the 1200 grit sand paper, rinse, wipe, and let the pieces dry.
After they are dry get a clean microfiber towel or cleaner cloth and start applying polish. (I used mothers because I couldn't find flitz).
Let the compound turn almost black/ grimy on the parts. Then proceed to wipe them off with another cleaner cloth.
After most of the compound is off I rinsed the parts to get it off hard to get places (barbs). When I did it some got inside the 3 way so I push the 3 way rod all the way through a few times and wiped it clean.
