Medium Dark Pewter (Interior) (WA110D) Touch-Up Paint for GMC

The Look

If you spend your days in a GMC Canyon or a heavy-duty Topkick, you know this color better than your own living room. It is the definitive interior shade of the late 2000s, a reliable grey that bridges the gap between industrial utility and passenger comfort. This color was designed to hide the dust of the job site while still looking sharp during the morning commute. Since your truck has likely seen its fair share of use over the last decade, you will find that this shade holds up remarkably well against fading, though it is prone to scuffs around the door handles and dashboard.

Technical Details

This is a metallic finish, which means it contains tiny flakes that catch the light to give your interior panels depth. Because of these flakes, you have to be careful during application. If you apply the paint too heavily in one spot, the metallics will cluster together and create dark, muddy patches. To get a professional result in your garage, you need to ensure the flakes lay down evenly. This depth is what makes the trim look like high-quality molded plastic rather than a flat, painted surface, so taking your time with thin layers is the only way to maintain that factory texture.

Best Practices

Before you begin to restore your GMC Medium Dark Pewter (Interior) (check for code WA110D), you need to locate your identification sticker to confirm the match. On the Canyon, look inside your glove box; for the Topkick, check the cab wall behind the passenger seat. Once you have the right match, shake the container for at least two minutes to fully suspend those metallic flakes. Test the color on the included card to ensure the shade and sheen match your existing trim. When you start, keep the container moving at all times to avoid heavy build-up. Allow for plenty of drying time between each light coat, as rushing the process will lead to a sticky finish that attracts lint and fingerprints.
