unless you have a serious amount of spare time id get em done pro, it takes absolutely ages, and youll struggle to get the finish that a 'refurb' company etc would, flatting down at the laquer/paint/primer to get to the bare alloy is a right @rse to start with, and some paint strippers (if you decide to use) can eat into the alloy its self.
once youve got to the bare metal youll need a mains powered drill really to put any real pressure with the 1st stage of the polishing kit (rough wheel and rough polish) and for all the other stages, when ive done this i use the industrial pillar drill at work on its highest speed settings and even that takes some serious time, then you change for your next softer wheel and polish and finally the soft mop and polish to try and get the 'mirror' effect.
just a little bit from my point of veiw, it is possible but more hard work than its worth!!!(unless you have decent equipment etc)
