COLOR CODE91/WA815K - Arrival Blue MetallicHummer Touch-Up Paint

The Look

This is the high-energy blue that defined the peak of the mid-2000s SUV era. While most H2 and H3 owners opted for safe blacks or desert silvers, this color was for the drivers who wanted their presence felt before they even arrived. It is a saturated, punchy blue that looks its best under direct sunlight, where the depth of the finish can actually compete with the massive chrome accents typical of these models. Since your Hummer has likely spent nearly two decades facing the elements, you might notice the original finish has lost some of its factory bite, but a fresh application of this pigment brings back that specific mountain-conquering vibrance.

Technical Details

This finish is a true metallic, which means it relies on a heavy load of aluminum flakes to catch the light. Metallic paints are notoriously temperamental because those tiny flakes are heavy; they want to sink to the bottom of your container or clump together on the surface. If you apply the paint too heavily in one spot, the flakes "drown" in the wet resin and flip onto their sides, making the touch-up look much darker and muddier than the rest of the panel. You need light, even passes to keep those flakes standing up so they reflect light correctly.

Best Practices

Before you spray or dab Hummer Arrival Blue Metallic (check for code 91/WA815K), you need to shake it for 60 seconds. You should find your paint code on the silver Service Parts Identification sticker located inside your glove box or occasionally on the driver's door jamb. Once you are ready to work in your garage or a patch of shade, test the color on the included card to ensure the flake density looks right. Whether you are using a nozzle or a brush, keep the container moving to avoid pooling. Allow plenty of drying time between thin layers rather than trying to cover the damage in one go. This layering process ensures the metallic particles distribute evenly across the repair.
