1993 Ford Mustang Cobra Bumper Repair
We recently repaired a 1993 Ford Mustang Cobra rear bumper for Duke's Body Shop. The bumper was made of polyurethane, and it had some pretty bad damage on it. Polyurethane is a thermoset plastic, and is NOT meltable. It can be repaired with the airless plastic welder and thermoplastic (meltable) polyurethane welding rod. This will not provide a fusion weld; the urethane welding rod is used more like a hot melt glue. We have some photos of the repair process below.
