making panels beautiful

[Hess Hodge]

Hello all,
I have been working on some faceplates and I was hoping that some of you
could give me some advice.  The panels are 1/8" thick aluminum and they
are pretty beat up from me working with them (drilling holes, measuring,
scratching, etc).  Anyone know how I can make them nice and shiny and
smooth?  Should I use a high-grit sand-paper?  Some sort of buffing
chemical?  Anybody have any tips or tricks?  Your help is appreciated...
