    removing clear coat

    Let me throw this out there.Would like to remove clear coat on wheels. Acetone did not do anything. Very fine steel wool takes awhile.Did this on my bike and steel wool cut threw alot faster ...guess the coating is not as thick. I`ll sit back now and wait for all the replys to come rolling in .
