Bumpers are often dented or distorted when they suffer a collision. Polyvance’s 6148 Bumper Rollers Kit makes the dent removal process much easier. The Bumper Rollers kit consists of three heavy-duty rollers ? one wide and flat, one ball-shaped, and one with a sharp edge which allows you to reshape body lines. In addition to removing dents from bumpers, these rollers also work well when applying sound deadening material.
