GMC Carbon Flash Metallic (WA565Q/58/GAR) Touch Up Paint

The Look

Since your Terrain has been on the road since the mid-2010s, you already know this color is a step above a standard flat black. It was the premium choice for the GMC lineup, designed to give the vehicle a more sophisticated, industrial appearance. In the shade or under garage lights, it looks like a deep, dark onyx. However, once you pull it into the sunlight, the heavy metallic flakes wake up, shifting the tone toward a dark charcoal with a distinct mechanical grit. This finish is excellent at hiding light road film, but it will show every swirl mark if you aren't careful with your maintenance.

Technical Details

This is a true metallic finish, which presents a specific challenge for your repair. The tiny silver and carbon-colored flakes inside the paint are prone to settling or clumping if the mixture isn't perfect. If you apply the paint too heavily in one spot, the flakes will sink to the bottom of the layer, making the touch-up look like a dark, muddy bruise. If applied too thin, the repair will look hazy and grey. You are aiming for a balanced distribution of flake to ensure the repaired area catches the light at the same angle as the original factory finish.

Best Practices

You will find your specific information on the service sticker located inside your glove box. Before you spray or dab GMC Carbon Flash Metallic (check for code WA565Q/58/GAR), you must shake the container for at least sixty seconds. Those heavy metallic particles love to sit at the bottom, and skipping this step will result in a color that doesn't match. Test the color on the included card to see how the flakes settle before you move to the vehicle. When you are ready to apply the paint, keep the container moving to prevent the metal bits from pooling in one spot. Respect the drying time between coats to avoid trapping moisture, which can dull the final shine.
