Minor damage to plastic bumper covers can be cost-effectively repaired with Polyvance's FiberFlex universal repair rod. FiberFlex is designed to bond with nearly any plastic, though it works best on today's common polypropylene and TPO bumpers. Unlike a true fusion weld, FiberFlex is a hot-melt adhesive applied with an airless plastic welder, similar to a brazing process. This video demonstrates how to repair a tear along the edge of a plastic bumper cover using an airless plastic welder and the FiberFlex repair rod.
