GMC Pewter Metallic (11/WA382E) Touch Up Paint

The Look

If you drive a high-mileage Sonoma or a trusted Suburban, you already know why this color dominated the road for nearly a decade. It is arguably the most practical shade General Motors ever produced because it handles the reality of the road better than almost any other finish. This is not a cold, clinical silver; it has a warm, champagne-like undertone that gives your Full Size Pick-Up or Jimmy a soft, sophisticated glow in the afternoon sun. More importantly for a daily driver, this tone is a master of disguise that hides road salt, dust, and light grime so you can go an extra week without a car wash.

Technical Details

This finish relies on a heavy concentration of metallic flakes to achieve its depth. While those flakes look great when the light hits them, they present a specific challenge for home repairs known as mottling. If the metallic particles are not distributed evenly, they can clump together or sink, creating dark splotches or stripes in the final finish. This usually happens if the paint is applied too heavily or if you do not maintain a consistent speed across the repair area. Because this color is a metallic, your technique determines whether the repair blends in or stands out as a dark patch.

Best Practices

To find your specific paint code, look for the Service Parts Identification sticker usually located inside the glove box or occasionally on the driver's side door pillar. Before you spray or dab GMC Pewter Metallic (check for code 11/WA382E), you need to shake it for 60 seconds to ensure those heavy metallic flakes are fully suspended in the liquid. Since your vehicle has likely faced years of UV exposure, the existing paint may have lightened over time, so you must test the color on the included card before moving to the car itself. When you are ready to begin, work in the shade and apply several thin, light layers. Keeping the container moving is the best way to prevent the flakes from pooling and ensure the repair looks uniform. Give each layer plenty of drying time so the finish sets correctly without sagging.
