Best way to polish metal?

[Chris_90]

So looking at polishing my xud rocker cover, wanting to do xantia inlet and some parts of the bosch to if i can.

Got to work with some 200 grit wet and dry and heres the results so far after about 10mins of sanding.




Then went in cos got arm ache (not used to all this rubbing )

Then did some more





And that's it so far.

So whats the best way to get a good finish? any hints and tips? was wondering if i could get something that would fit in drill or grinder that would help out instead of doing it all by hand?

Comments welcome
