Buff finishes.....
Maybe you have already heard, but this is what I do:
I cut the head off of a Long, thin, wood screw, I take Some wool felt, or an old shirt like that of a work uniform(the polo-type shirts, not mechanic-type) and I cut a whole bunch of little circles (1-1 1/2 ") and after making sure they are stacked even, Sew them close to the center to keep them together with some strong thread. After doing this, I put the headless screw into my drill and drill it into the stack of felt circles.
You know have a gentle buffing bit for a dremel tool that won't tear a hole through your model, and will produce an awesome sheen.
