SERVICE INFORMATION

Although this bulletin provides information regarding identification, repair and refinishing of polyurethane and polypropylene bumper fascias on Nissan vehicles, the repair technician may benefit from participation in a comprehensive automotive plastics repair course.

Caution:
When repairing or refinishing bumper fascias, it is important to use the appropriate products for the material you are refinishing. Refinish paint may not adhere if the part has not been properly repaired, cleaned and prepped (refer to PI94-003).

A polyurethane bumper fascia can be distinguished from a polypropylene fascia by using the following 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.

Alternate checks:

1. Refer to the appropriate Body Repair Manual that supplies information regarding bumper fascia materials.

2. The bumper fascia material can be identified by the material codes PUR or PP embossed on the inside of the fascia.

Refer to chart for identification of applied model bumper fascia materials.
