Ive got a new set of American Torque-Thrust wheels that sat on a car I'm building for the street for 5yrs....They have got VERY grungy/pitted looking.....Does anybody have experience with sanding/acid etching/polishing wheels like this? I can get the wide outer "ring" sanded/scotch brited/and polished in the lathe. ...not perfect but look pretty good ...the 5 spokes in the center are the bytch....I was thinking a low pressure blast with new glass bead maybe? Then polish with compound ?
