Chevrolet White Diamond Pri Metallic Tricoat (98/WA800J) Touch Up Paint

The Look

You chose the premium aesthetic for your Avalanche, Suburban, Tahoe, or Silverado. During its run from 2007 to 2011, this was the luxury standard that separated high-trim trucks from the standard fleet. It is a creamy, sophisticated white that glows rather than just reflecting light. Because your vehicle has likely spent over a decade out in the elements, the original finish might have shifted slightly toward a warmer yellow compared to the fresh paint in your hand. This is a high-end look that rewards patience, but it requires a careful touch to maintain that deep, liquid glow.

Technical Details

This is not a simple metallic or a solid color; it is a complex tricoat. This means the finish is built like a sandwich: a solid base, a translucent middle pearl layer, and a clear topcoat. The "diamond" effect comes from that middle layer. The biggest risk you face is mottling or tiger stripes, where the pearl particles cluster together and create dark or cloudy patches. If you apply the middle layer too heavily, the repair will look darker or more yellow than the rest of the body. Keeping the container moving is the only way to ensure the pearl flakes lay down in an even, shimmering blanket.

Best Practices

To verify your match, look inside your glove box for the Service Parts Identification sticker. Before you spray or dab Chevrolet White Diamond Pri Metallic Tricoat (check for code 98/WA800J), you need to shake it for 60 seconds to ensure the heavy pearl sediment is fully mixed. Work in a cool garage or the shade to prevent the paint from drying mid-air. Always test the color on the included card first. This allows you to see how many layers of the pearl mid-coat you need to reach the right depth. Allow plenty of drying time between each pass so the finish stays crisp and the pearl does not sink into the base.
