Material Description. This standard describes the surface appearance and quality requirements for GM assembly plant painted vehicle exterior body panels, supplier painted body panels, and supplier painted fascias and exterior add-on parts, and primed parts. The requirements are described in terms of appearance attributes and surface blemishes for each zone that a body panel, fascia, or add-on part is located on a vehicle.

This standard applies to primed and/or finished parts topcoated in GM assembly plants or produced and topcoated by suppliers. The standard also includes requirements for paint suppliers.
