Imagine what it's like to polish a whole Aluminum airplane! <:-))
It takes me some 5 hours just to do a prop spinner.

One think you could do is clean it with the fine Scotch Brite and then 
use Alodine (which is also a lot of work) which will give it a nice, 
tarnish resistant Gold color.  Unfortunately the Alodine finish is a bit 
fragile from a mechanical standpoint.
