I once had to drive a company van that some nimrod had armoralled the WHOLE vinyl interior, including the floor, gas pedal, brake pedal, everything. Driving it was an interesting experience, as the only thing holding you on your seat was the seatbelt, and barely that. Even the steering wheel was armor-all'd. And boy, that stuff is SLICK! I wouldn't put it on tires, for fear of slipping more than anything.
