Very Light Platinum (Interior) (WA834T) Touch-Up Paint for GMC

The Look

This is the technical, cool-toned silver that defines the modern cabin of your Terrain. During its brief run from 2018 to 2019, this color acted as the bridge between the rugged GMC exterior and a more refined, industrial interior. It is most often found highlighting the center console and the bezels around your vents. Since your Terrain has likely spent a few years on the road, these trim pieces often pick up nicks from keys or rings. Fortunately, the light tone is excellent at hiding the typical dust and fingerprints that usually plague darker interior plastics.

Technical Details

You are working with a metallic finish, which requires a bit more focus than a basic solid color. The tiny flakes inside the paint give it that premium shimmer, but they can also look "mottled" or blotchy if the paint is applied too heavily. If the flakes don't land evenly, the trim can end up looking striped. This happens because the heavy paint allows the metallic particles to sink and group together instead of standing up to catch the light. Before you spray or dab GMC Very Light Platinum (Interior) (check for code WA834T), you need to shake the container for a full minute to get those flakes properly suspended.

Best Practices

To verify your match, look inside your glove box for the silver Service Parts Identification sticker; the code is usually listed near the bottom under the "BC/CC" heading. When you are ready to begin, find a spot in your garage or a patch of shade where the interior surfaces are cool to the touch. Test the color on the included card first to see how the metallic flakes settle. Whether you are using a nozzle or a brush, keep the container moving and apply the paint in thin, light passes. Give it at least ten minutes of drying time between layers to prevent the silver from looking muddy. Once you are finished, a light clear coat will help match the original factory sheen and protect the finish from future wear.
