George, I dont own any Torque Thrust wheels currently, nor have I ever tried to restore any. I am old enough to have served in Viet-Nam in 68'and do have a rememberance of "the look".
I would not think that GLASS beading would replicate the original look as they left the foundry. Would not glass beading create a look other than the as cast appearance. Many aluminum foundry operations, use a STEEL shot blaster
with different sizes of shot and differing amounts of time, to remove all the mold sand, etc.....
This of course would be done before any machining and polishing is done....
Just my thoughts..........
