Polyvance's 6450 Bumper Bag Plus is a versatile tool that works in many different areas of the body shop. Use it to take small dents out of plastic bumpers and sheet metal, adjust the fit of adjoining sheet metal panels, and even use it to cushion a jack saddle to eliminate the risk of damage to the subframe. Bumper Bag Plus is made from 70,000 pound tensile strength webbing and is practically indestructible. However, it is also soft enough to conform to the shape of whatever it is pressing up against. This allows it to take the energy of the force and prevent further damage to the area.
