Hummer Imperial Blue Metallic (37U/WA403P) Touch Up Paint

The Look

Imperial Blue Metallic gave the Hummer H3 a needed dose of maturity in 2007 and 2008. While earlier models leaned into bright yellows and oranges, this deep navy finish made the truck look heavy and expensive. In the shade, your H3 might look almost black, but direct sunlight pulls out a complex blue that highlights the boxy lines of the fenders. Since your vehicle has been tackling the elements for over fifteen years, the original finish has likely weathered, making a clean repair vital for keeping that curb appeal.

Technical Details

This is a true metallic finish, which means the paint contains tiny flakes that provide its depth. Metallic paints often mottle, where the flakes clump together and create dark or light stripes in the finish. If you do not keep the flakes suspended in the liquid, the blue looks flat and dull compared to the surrounding panels. Because the H3 has many flat, vertical surfaces, any inconsistency in the flake distribution stands out when the sun hits the side of the truck.

Best Practices

You can find your paint code on the silver or white sticker located inside the glove box. Before you spray or dab Hummer Imperial Blue Metallic (check for code 37U/WA403P), you need to shake it for 60 seconds to ensure the metallic flakes are evenly mixed. Test the color on the included card to see how it looks once it reaches its full drying time. When applying, keep the container moving to prevent the paint from pooling, and work in a cool garage or under some shade to keep the surface temperature down.
