62U/WA916K - Dark Blue MetallicGMC Touch Up Paint

The Look

Since your Sierra has been on the road since 2006, you likely know that this shade is a bit of a rarity. This deep, sophisticated navy was only available for a short window, making it a "blink and you'll miss it" option in the GMC lineup. On the road, it carries a heavy, professional presence that mimics black in the shade but reveals a sharp, oceanic depth when the sun hits the panels. Because your truck has been out in the elements for nearly two decades, your original finish may have slightly aged, so bringing back that factory-fresh navy requires a patient touch.

Technical Details

This is a true metallic finish, which means it relies on tiny aluminum flakes to create its signature sparkle. These flakes are significantly heavier than the blue pigment and love to settle at the bottom of the container. If you do not mix them thoroughly, your repair will come out looking too dark and dull because you are only applying the pigment without the metal. You also need to watch out for mottling-those ugly dark splotches or stripes that happen when flakes clump together. This usually occurs if the paint is applied too thick, causing the metallic particles to "drown" and lose their orientation.

Best Practices

Before you spray or dab GMC Dark Blue Metallic (check for code 62U/WA916K), you need to shake it for 60 seconds. You can confirm your code by checking the service sticker located inside your glove box; look for the "BC/CC" text near the bottom. Once you have the flakes suspended, test the color on the included card to ensure the sparkle matches your Sierra's current look. Work in your garage or the shade to prevent the metal from drying too fast and standing on edge. Apply several thin layers rather than one heavy coat, and always keep the container moving to ensure the finish stays even and smooth.
