Repairing a Tear on the Corner of a Bumper
In this video, we’ll be focusing on one of the most commonly damaged areas of a plastic bumper. The corner of a bumper is fairly weak and can sustain damage even if it’s not directly impacted in a collision. A collision repair technician can repair this type of damage and restore the bumper to like-new condition using products and equipment from Polyvance.
For this demonstration, we’ll be using a polypropylene bumper with an L-shaped crack that runs along a body line. We will repair the crack using Polyvance’s polypropylene welding rod and a nitrogen plastic welder and refinish the bumper using flexible filler and waterborne primer. Using the techniques shown in this video, a collision repair technician can repair this type of damage on most plastic bumpers.
