COLOR CODEG42 - Coastal DuneGMC Touch-Up Paint

The Look

This is the breakout shade for the 2026 Canyon, and it captures the rugged, utilitarian aesthetic that defines modern truck design. It sits somewhere between a pale sand and a light silver, leaning into that "overland" look that makes your truck look capable even when it is just sitting in the driveway. Because this color is inspired by natural beach landscapes, it is incredibly forgiving. It hides light road dust and salt spray better than almost any other color in the current lineup, keeping your Canyon looking clean deep into a road trip.

Technical Details

Unlike many of the other options for this model year, this is a solid finish with no metallic flake. This makes your job much easier because you do not have to worry about metallic particles clumping together or creating dark shadows. However, solid colors are honest. They show the "edge" of a repair more clearly than a sparkly paint would. While you won't deal with mottling or tiger stripes, you must ensure your surface is perfectly smooth. Any ridge or bump in the primer will stand out under this flat, earthy tone once the clearcoat goes on.

Best Practices

You will find your paint code on the silver Service Parts label, which is typically located inside your glove box or on the driver's side door jamb. Before you spray or dab GMC Coastal Dune (check for code G42), you need to shake it for 60 seconds to ensure the pigments are fully integrated. Always test the color on the included card before you touch the truck to verify the shade matches your specific batch. When applying, keep the container moving to avoid heavy build-up in one spot. Respect the drying time between thin layers; this patience prevents the paint from sagging and ensures the final finish looks like it came straight from the factory.
