I've seen people use automatic polishers(made for jewelry I think). What I've been using to polish is some Noxon metal polish. seems to do the job very well. I don't think an automatic polisher would be worth it just for mods.
just dont use brasso, left A LOT of micro swirls on my top cap
Cape Cod. You cant go wrong. Seriously.
For a mirror finish SS go to the hardware store and buy a tube of white buffing compound for stainless steel. This is the finest grade for SS. Use it with a flannel buffing wheel. The wheel type that fits a power drill works just fine. Don't use much of the buffing compound which is applied to the wheel. Disassemble to avoid using buffing compound on the brushed SS, or mask it with tape.I have some very light surface level scuffs on the polished SS top cap on my aqua (imgur: the simple image sharer scuff is to the left of the hole in the ring) from my girlfriend dropping my mod on the sidewalk... Luckily it landed on the drip tip, but the lock ring & atty top cap took a scuff..
What's the best method for getting them out of SS? Can I just go right to polishing? Also my dremel is buried behind a wall of .... in my storage unit, so if there's a way to do it by hand that will take less than the ~3-5 hours it will take to get to my dremel that would also be amazing.
