My car dealer, Green Lincoln in Greensboro, NC, took pity on me and acid-washed the overspray off my chrome wheels gratis. No effect on the rubber, so I've personally put in 15 hours removing this product from three tires; I still have one to go... seems after scrubbing with tire cleaner and pressure washing the tires the product will rub off with a rag and a lot of elbow grease, but I found that pencil erasers work best. Yikes... you have been warned!
