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
