GMC Ashen Grey Metallic (WA810T/GLJ) Touch Up Paint

The Look

Your GMC Terrain was built to handle daily life without losing its edge, and this color is the reason why. It is a deep, smoky grey that feels more premium than a standard charcoal. Because your car has likely been on the road for over a decade, the finish has probably weathered its fair share of sun and road salt. This shade is excellent for hiding road grime and minor surface dust, but it does require a bit of patience to match perfectly against original panels that have spent years in the light.

Technical Details

This is a metallic finish, which means the paint is packed with tiny flakes that give it that signature shimmer. The main challenge you will face is mottling, or what looks like dark streaks in the finish. If the paint goes on too heavy or unevenly, those flakes will bunch together and create blotchy patches. You want those metallic particles to lay flat and dispersed so the light hits them evenly across the entire surface.

Best Practices

Before you spray or dab GMC Ashen Grey Metallic (check for code WA810T/GLJ), you need to shake it for 60 seconds. This is non-negotiable because the heavy metallic flakes settle at the bottom of the container. You can verify your code on the silver Service Parts sticker located inside your glove box. Test the color on the included card first to get a feel for the flow and how the metallic particles settle. Work in the shade, keep the container moving, and apply thin layers. Give the paint plenty of drying time between passes to ensure the finish stays crisp and level.
