Aluminium polishing!
Hmmmmmmmmmmmmmmmmmm!
my personal opinion is that the polishing of aluminium to a chrome
like finish is severly detrimental to the heat shedding capacity of
any part on any motor.
If you want that sort of finish, fine I can accept that.
But if you want the ORIGINAL finsh with its efficient heat shedding
properties, just grit blast the item to remove any insulating covering
and - JOB DONE!
A LIGHT spray of matt black will improve the heat loss but that may
not be acceptable if you are going for the original look.

What you're missing is a mess :)
I polished aluminum parts and it was messy, very, very messy. On cast
parts
you'll need to grind/sand them smooth and then use large buffing
wheels on
your bench grinder using stainless compound and then rouge if you so
desire
but IMHO a waste as the stainless makes the aluminum shine well and it
cuts
fast.
Messy, very messy.
If I had to do it again I'd send them out to be done and save yourself
a
mess and a lot of time and equipment that you'll need to do it
correctly.
