1978 Trans Am Bumper Repair

We recently repaired a 1978 Trans Am front and rear bumper. The bumpers were made of polyurethane, and they were in pretty rough shape when they arrived. Polyurethane is a thermoset plastic, and is NOT meltable. It can be repaired with the airless plastic welder. This will not provide a fusion weld; the urethane welding rod is used more like a hot melt glue.

To do this repair, we used an airless plastic welder, R01 polyurethane welding rod, 2000-T Flex Filler epoxy, and 3043 All Seasons Black Jack waterborne primer surfacer. We have posted some photos of the repair process below.
