GMC Black Carbon Metallic (Interior) (WA700S) Touch Up Paint

The Look

This shade isn't your standard utility black. It serves as a high-tech accent in the cabins of the 2017 and 2018 GMC lineup, specifically framing the dashboards and door panels of the Sierra and Yukon. If you drive a Canyon from this era, you likely have this color protecting the trim pieces that give your truck its industrial, premium feel. Because it was designed to mimic the depth of woven composites, it has a sophisticated character that stands out against the flatter plastics of the interior. Since these surfaces live inside your vehicle, they haven't suffered the same UV beating as your exterior paint, so the original finish usually retains a sharp, crisp depth.

Technical Details

The finish on your trim is a true metallic, which introduces a specific challenge for any repair. Before you spray or dab GMC Black Carbon Metallic (Interior) (check for code WA700S), you need to shake the container for at least sixty seconds. Metallic flakes are heavy and naturally sink to the bottom. If you skip the mixing, the color will look like a muddy grey rather than a metallic black. Getting those flakes suspended is what gives the repair that factory shimmer. This paint is thin by design to allow the metallic particles to lay down correctly, so don't expect it to cover a deep gouge in one heavy pass.

Best Practices

You can find your paint code on the silver service sticker located inside your glove box; look for the line marked "BC/CC." Before you start the actual repair, test the color on the included card to verify the flake density looks right. Whether you are using a nozzle or a brush, keep the container moving to ensure the metallic mix stays consistent. Apply the paint in light, thin layers rather than one thick coat. Heavy applications often lead to mottling, where the metallic flakes cluster together and create dark splotches. Giving the paint enough drying time between these light layers ensures the finish stays flat and professional.
