To Anyone Who Has Polished Aluminum

[Alero2k4]

I want to polish my calipers. I sent something to ssbc and this is what I got...

Robert,
You can polish your aluminum calipers just like any other piece of
aluminum. The only things to keep in mind is not to go too deep when
sanding and do not get any polishing compound or aluminum shavings into
the caliper on the pads or rotors. You may want to rebuild the caliper
when done polishing so you know that there is not shavings in the seals.
Sincerely,

Bill

I really don't want to completely unhook my brake lines and everything so that I have to bleed the brakes...Do you think I could do this with the calipers on the car still??? Even if I unbolt the caliper itself, I just don't want to unhook the line... Thoughts, ideas, suggestions???

Edit: Also, I am thinking I will polish the caliper, and then paint the other piece red...do you think this would look ok???
