Be really glamy and have it annodised!
(like chrome for aluminium...but you can have any colour at all, including changeable oil-slick chromatic finishes).
Powder coating would be a good idea, except for the hassle of needing to strip out the contents of the pedestal (no problem if you are doing that anyway as part of maintenance). Powder coationg involves a baking stage and the bushes and plastic inside the pedestal would not thank you for that.
(Yes, you would also need to strip it fully for the annodising process)
