Description Busch 8″ Firm Treated Yellow Buffing Wheel (3 Pack) This Wheel is made with yellow treated 86/80 cotton fabric.  5/8″ arbor hole. Rouge bar selections  I would suggest for buffing aluminum would include Menzerna 439T, Matchless Brown 751EZ, JacksonLea brown D-32, or your own favorite brown tripoli bar. On stainless steel a gray stainless bar can be used. (See under “Polishers, Rouge Bars, and Buffing Wheel Sets.”) Related
