Hi Laura,

    I have met several jewelers who "know" that platinum should be
    isolated from tools used for other metals, but have never followed
    that practice myself. None of my platinum work has ever shown any
    sign of corruption, so I really have no idea what it is that they
    fear. But several of my friends insist that using the same buffs or
    files on platinum and other metals will be disasterous. If I were
    you I would use Fabuluster. A good pre-polish is difficult with most
    of the regular buffing compounds, so I would recomend sanding with
    600 or finer sand paper first, to get out the scratches. 

    If anyone can explain what evil it is that we are supposed to be
    avoiding by using different equipment for finishing platinum, I am
    eager to be enlightened.
