i use to build polished air flowed carbs up in the garage and used the same technique on various bike parts.
for around 10 to 15 gbp you can get three polishing wheels (mops plus attahcment for drill and the wax needed)(ideally used on polishing machine) but they just go onto the end of a drill.
most recently i polished the tip of this sante crank (it was dull and oxidised when i got it where the paint had come off) only 15 minutes work
