    Having just spent an afternoon in the shop with theses new wheels I
    have to say that I like them a lot. The finish I achieved was like a
    good tripoli polish maybe a little better. It just took a brief
    moment with rouge to achieve a final finish. 

    a couple of comments: 

    You are better off with a slow speed  (1725 rpm ) polishing motor,
    the 3600 rpm spindle speed is really too fast especially with the
    1500 and 3000 grit wheels. 

    There was less softening of the edges on the pieces than I would
    have achieved with  muslin or cotton buffs. The wheels are a lot
    stiffer than cloth wheels but still more conformable than a soft
    felt wheel. 

    Much cleaner than working with polishing compounds :-) 

    A water dish next to the wheel that you dip the work in to keep the
    work cool and help lubricate the wheel is a great advantage here and
    something you would never use with greasy polishing compounds and
    cloth wheels. So no burned fingertips :-) 

    I started with a rough surface and went to a excellent pre polish
    starting with a Scotch-Brite EXL 2SFIN wheel followed by these new
    FX series wheels. 

    I think these are another home run by 3M just like the Radial
    Bristle Discs
