Paint: Application and ID


Paint Identification

Caution:Exposure to isocyanates during paint preparation and application processes can cause severe breathing problems. Read and follow all of the instructions from the manufacturers of painting materials, equipment, and protective gear.

Important:Always refer to the GM Approved Refinish Materials book. This book identifies the paint systems you may use.

The latest revision of the GM Approved Refinish Materials booklet is located on the Goodwrench website at www.gmgoodwrench.com.

Use the service parts identification label to identify the type of paint technology, paint codes, trim level, and any special order paint colors on the vehicle. Refer to Vehicle Certification, Tire Placard, Anti-Theft, and Service Parts ID Label .
