Restoring and endura bumper

Here's one of the more rare bumpers we've fixed up this year. This is a 1970 Pontiac GTO Endura bumper. It is made of thermoset polyurethane molded over a steel frame. The bumper is extremely heavy; it weighs 75 pounds! A bumper like this would be very expensive to replace, but it can be repaired with our airless plastic welder, urethane rod, and 2000 Flex Filler.

This video demonstrates how to repair thermoset polyurethane.
