SERVICE INFORMATION

This bulletin provides detailed instructions to repair polyurethane and polypropylene bumper fascias. A polyurethane bumper can be distinguished from a polypropylene bumper by using the following test:

Cut a small piece of material from the end of the bumper fascia and hold it over the flame of a match or lighter until it ignites.

Polyurethane will burn with black smoke and have an odor.

Polypropylene will burn with little smoke and will not have an odor.


Alternate Test:

Sand an area near the damage with a 36 grit disc.

If the material sands cleanly, the bumper is polyurethane.

If the material melts or smears when sanded, it is polypropylene.
