Sand sand sand! Start with something very hard like 80 grit (start with a buffing wheel if your grinding the ridges), then move up to 200, 400, 800, 1000 and anything more is preference. Finish up with some aluminum polish and dazzle.
yeah that's pretty much it.... i started with an 80 - 120 - 220 - 600 (all on an orbital) dremel with a 120 grit attachment to get in corners then i used my bench buffer from a 1 (hard metal compound) - 3 (soft metal compound) - 5 (light polish) and after i clean them in the parts washer i'll throw some wenol on them
i think if i went to a 1000 then 2000 grit by hand, then bench buffer, it would literally be a mirror finish
today i think i'm gonna do the compressor housing on the turbo and see how that works out, and if it turns out good, i may start doing a little polishing on the side and charge like roughly $10/hr for work
