BASECOAT/CLEARCOAT PAINT PLANT PRODUCTION CHANGES

1986 6000 AND STE MODELS

In January of 1986, the Oshawa Plant #1 changed from lacquer to the Basecoat/Clearcoat (BC/CC) paint system starting with VIN 2G2AF19X6G9266233.

From SOP, (1/20/86), no "WA" numbers were being used on Service Parts Identification Label (S.P.I.D.). In later production, the plant started using the lacquer "WA" numbers. However, new "WA" numbers have been assigned and appear on the S.P.I.D. label starting with VIN 2G2AH19W5G9274215. When refinishing all BC/CC 1986/87 Oshawa Plant #1 production, these new "WA" numbers must be used to achieve an acceptable color match when repairing the BC/CC finishes.

To aid in identifying this plant, the eleventh position in the VIN will be a "9." Refer to the list included with this bulletin for correct "WA" numbers for each color.

Follow the paint manufacturer's recommendations when repairing the BC/CC finishes.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
