The Look

If you own a Sierra or a Canyon from the 2020 to 2022 era, you know this shade isn't just another silver. This color acts as the industrial backbone of the GMC lineup. It is a deep, brooding charcoal that gives the Acadia a professional edge while making the Savana look like it belongs on a high-end job site. Because it sits right in the middle of the gray scale, it does a heavy lift hiding road salt and dust. In the shade of your garage, it looks like solid granite, but once you pull it into the light, the metallic depth reveals itself.

Technical Details

This is a true metallic finish, which means the appearance of your repair relies on how those tiny flakes of aluminum and mica settle. Before you spray or dab GMC Dark Shadow Metallic (check for code WA626D/WA694D/GJI/GUN), you must shake the container for at least a full minute. If you skip this, the heavy flakes stay at the bottom, and your repair will look like a flat, muddy gray. This color is sensitive to how it's applied; if the paint goes on too wet, the flakes sink and create dark patches called mottling. Keep the container moving to ensure the metallic particles stay suspended and even across the repair area.

Best Practices

You can usually find your paint code on a silver or white sticker inside the glove box for the Sierra, Canyon, and Acadia, though Savana owners should check the door pillar or under the driver's seat. Since your vehicle has seen a few years of sun and road debris, the original finish might have aged. Test the color on the included card to verify the match before you touch the bodywork. Whether you are using a nozzle or a brush, work in thin, light layers and respect the drying time between each pass. The final depth won't truly show up until you apply the clear coat, so do not panic if the base looks a little dull at first.
