Description / Abstract:
Material Description.
This specification defines the performance requirements for pre-treatment, paint materials, and processing required to paint/coat aluminum road wheels. In some cases, this specification might be applied for aluminum wheel trim. Coating/Paint durability requirements are also included.
Note: For chrome aluminum wheels and wheel trim, refer to GMW15774. For chrome plated plastic wheel trim (including claddings) refer to GMW14668.
Symbols. Not applicable.
Applicability.
Painted aluminum road wheels and wheel trim.
Classification/Wheel Types.
• Type A. Wheels with any clear paint(s) over bright metal sections of the disc outer and/or rim flange, for example, bright polished wheels and machined-faced wheels.
• Type B. Fully color painted wheels without any areas of clear paint(s) over bright metal on the disc outer and/or rim flange.
Remarks.
This specification applies to all surfaces that are designated on the engineering part drawing to meet these requirements. Painted parts must meet these requirements prior to going into the field and must also satisfy GM’s and its customers’ expectations for appearance and cosmetic durability. All deviations from this specification must be agreed upon by GM and must be documented on the part drawing.
