    Hey Joel, The first question to address is just how rough the surface
    is. Are there file marks from carving wax or was it glass smooth b4
    casting? 99.9% of the time it is easier to work in wax... get it
    perfect!!! Saves on lost metal, casting weights, finishing time,etc.
    etc. etc. I really try everything I can get my hands on( and have for
    20 yrs)I own 3 sizes of the 3m brushes and for 10% of my projects I
    break them out. Usually to work on and around heads and other small
    contours. They don't really do the trick for flat, large, sharp
    surfaces. After tons of practice nearly everything is done with
    silicon abrasives. ALWAYS DRAG, NEVER PUSH!!!! Finish all crevices,
    heads, holes, channels PERIOD b4 setting stones!!! It takes time yes,
    but it separates you from others right away. For your first 18k piece
    use what you Know works for 14k and it's all good.

    Joel, I Just realized that I didn't make it clear that I was
    speaking of pre-polish when I spoke of the silicone wheels. Final
    polishing, is natural brushes and buffs, 3m green rouge (med cut)
    leaves a rich color and cuts pretty fast, red... higher shine. For
    smaller harder to reach places, anything from cotton shoe laces( or
    string with polish, to polished out broken burs to burnish...
    whatever fits and burnishes
