I originally posted this on the Detailing Univ. forum, but didn't get any help. My father-in-law gave me his 8" Random Orbital Polisher and I can't find any pads to use with it. It has a disc with about 3/8" of spongy rubber. I don't think I can take the disc off. The only thing I can think of doing is putting velcro on the disc so I can use the velcro backed pads. Will this work?
