Aluminum tarnishes easily after being polished because of how it rusts. As it oxidizes it create a very, very thin layer of crystal over it's surface that unlike iron does not expose new metal to air, it actually protects the metal under it from oxidizing. that is why aluminum seam to be a non corrosive metal, when it actually is. so why should you know that?
After you buff it wash it with plain distilled water (not tap water) or alcohol and wipe it dry with a clean terry cloth. then let it sit over night. this will allow it to re-build that layer of protective crystal. when you put any kind of protective compound on it before it has a chance to build that coating it will prevent it from forming and will tarnish easily.
I just really want a bike with a turbo, because their are those times when you pull up too a stop light next to a cop, and I think a really loud PPTTTSHIIISHHHHHHHH would make his day. =P
