COLOR COAT CHIPS OFF GUIDELINES FOR INSPECTION

ALL MODELS

The paint used on all models is designed to withstand certain impact forces without chipping. However, the color coat may chip off on some body panels depending upon a vehicle's design features (hood slope angle, size of front end panel, rocker panel turn under), age, and the severity of impacts.

Chipping paint is caused by the top coat fracturing when impacted by salt, stones and road debris.

Conditions of chipping paint should be carefully evaluated to determine if the cause is related to a paint problem or debris impact. When determining the cause, the following guide lines should be used as reference.

INSPECTION GUIDELINES:

1. Prior to inspection the body exterior should be clean and free of dirt.

2. Carefully inspect all horizontal and vertical body panels for chips.

3. Carefully inspect windshield glass, side glass, and exterior moldings for chips and dents.

4. Tape Test Chipped Area:

Apply a piece of water proof tape approximately 10 inches long over area to be tested. Remove tape with one quick even pulling motion 90 degrees to body panel.

INDICATIONS OF PAINT PROBLEM:

0 Body panels are chipped and windshield glass and exterior moldings are free of chips and dents.

0 Tape Test removes paint in areas not affected by impact.

INDICATIONS OF IMPACT DAMAGE:

0 Body panels, windshield glass, side glass, and exterior moldings show signs of chips and other damage.

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.
