okay, heres the deal,
i just acquired a set of BBS RS, all the lips have some imperfections, just dirt from what i see, i have sanded using a sanding block by hand, with about 200 grit or so, then i did 400,600,800, 1000, and finally 1500.
after all that there is still some grit or something, but its just not coming out, i thought about a dremel, but i cant muster up the balls to do it, and possibly screw up the grain of the metal, and end up screwing up a part.
basically im asking,
should i use a bit on a drill? if so what?
should i try sanding with a different grit?
after sanding i polished it and they are nice, but not quite mirror, how can i get that finish.
