Description Busch 8″ Medium/Light Untreated White Buffing Wheel (3 Pack) This wheel is made with 86/80 cotton fabric. The arbor hole is 5/8″ . Rouge bar selections I would suggest for use on aluminum with this buffing wheel would include Menzerna Blue 480 BLF, Matchless Blue, Jacksonlea White. On stainless for more aggressiveness you could use the Jacksonlea Green C-2 listed below, or another medium-cut bar of your choosing. Related
