After using the Eastwood Fender Roller on the front wheelwells of the truck, the lip sits flat against the fender. This netted two great things: extra tire clearance and a smooth contact surface. If the tire happens to rub, it will get polished instead of gouging the sidewall. This is no wimpy contraption, this is a built-to-last tool that can be used over and over. Just remember, it can be used to roll fender lips, flare fenders, and speed up collision damage repair.
