Welcome your new child!
I'm not sure of which type of finish you're looking for. If you just want to "brighten" the aluminum, then stripping and waxing with a product like Walbernize (sold by Airstream) or Liquid Glass would do the trick.
If you REALLY want to get some exercise, and have a "hobby" that's even better than pulling weeds (which, I really dislike doing), then polishing for a mirror like finish is what you want to do.
Search "polishing" ... and then sit a while to hear everyone's different take on it.
Or.. you can visit "www. perfectpolish.com" (I think that's the link) and see how they do it.
You can also get a good idea by looking at Shari (moderator) personal site... it's in the "links" section of this forum under individual's restoration sites.
Good luck, and post away!
