WA403P - Imperial Blue Effect Hummer Touch Up Paint

The Look

In 2007, Hummer owners who wanted to trade the loud yellow and red for something more sophisticated chose this shade for their H2 or H3. This is a regal, midnight blue that stays subtle until the light hits the metallic flakes, making the heavy body lines of your truck look more refined. Since your Hummer has spent its life exposed to the elements, the existing finish might have lost some of its original depth, so your goal is to bridge that gap between the weathered surface and the fresh pigment.

Technical Details

This is a metallic finish, which means it relies on tiny silver and blue flakes to create that signature depth. These flakes are heavy and tend to sink, so if the application is uneven, you might end up with mottling-a condition where the metal bits bunch together and look like dark clouds on your door. To prevent this, you need to ensure the flakes stay suspended and lay flat. A consistent spray distance and steady flow are your best defenses against a blotchy repair.

Best Practices

Before you start work on Hummer Imperial Blue Effect (verify your code WA403P on the white or silver sticker inside your glove box), you must shake your tool for a full sixty seconds to mix those heavy metallics. Test the color on the included card to see how the flakes settle before you touch the vehicle. Keep the container moving at all times to avoid pooling. Work in a cool garage or a patch of shade to keep the metal surface from getting too hot, which can cause the paint to dry before the flakes have a chance to level out. Apply several thin layers rather than one heavy one, and give each pass plenty of drying time to ensure the repair stays flat.
