I've got a tub of rubbing compound, we got it for our car. I tried it on a spare ball and it gave a respectable looking compoundy finish. Probably he doesn't care, so I'll likely go with something like a green or maroon pad and a light coat of Legends polish if the rubbing compound doesn't work.
Really I was worried about the abrasives and the particles, not quite as much about the surface finish. Thanks.
