As the definition of “classic cars” now encompasses vehicles from the 1970s and 1980s, people are starting to restore cars that were originally equipped with polyurethane bumper covers.
Polyurethane bumper covers were first introduced in the late 1960s and started to become widespread following the adoption of 5 mph (8 km/h) low speed impact rules first introduced in 1973.
These regulations required that following low speed collisions, the bumper was able to return to its original shape.
Most polyurethanes of that era were yellow, but not all urethanes are yellow. Polyvance’s latest video shows you how to identify this plastic and the special techniques required to repair it.
The video also provides a wealth of knowledge in plastic repair and proper restoration techniques for these bumper covers.
While this particular video focuses on how to restore a third generation (1982-92) Chevy Camaro front bumper cover, the techniques can be applied to many urethane covers from this era.
