WA715U/GNX - Bottle Green Metallic GMC Touch Up Paint

The Look

Since your Sierra was built in 2013, you are driving a truck with a bit of a secret. This shade was a one-year wonder, making it one of the rarer factory finishes for that generation. It acts as a chameleon; in a dark garage or under evening clouds, the truck looks nearly black. However, once you get it into the sunlight, the deep forest tones wake up. It is a sophisticated, earthy color that avoids the flashy look of brighter greens, favoring a more rugged and premium feel that suits the lines of the Sierra perfectly.

Technical Details

This is a true metallic finish, which presents a specific challenge during your repair. The paint is loaded with fine metallic flakes that give the color its depth and shimmer. If you apply the paint too heavily in one spot, these flakes can sink or bunch together, causing a phenomenon called mottling. This looks like dark, cloudy blotches or uneven stripes in the finish. To avoid this, you need to focus on building the color with multiple light coats rather than one thick one. This allows the metallic particles to lay flat and catch the light evenly across the repair area.

Best Practices

To confirm you have the right match, look for the silver Service Parts Identification sticker located inside your glove box. Before you spray or dab GMC Bottle Green Metallic (check for code WA715U/GNX), you need to shake it for 60 seconds. Metallic pigments are heavy and settle at the bottom of the container, so thorough mixing is the only way to get the right shade. Test the color on the included card to see how the metallic flakes lay down before you touch the truck. Keep the container moving at a steady pace to ensure a balanced flow, and give the paint plenty of drying time between layers so the finish stays crisp and level.
