GMC Bright Blue (42/WA9203) Touch Up Paint

The Look

This is a pure, no-nonsense blue that defines the utility of the late eighties and early nineties. Whether it is on a Suburban or a Heavy Duty truck, this shade was designed for vehicles that had jobs to do. Since your truck has likely been a workhorse for over thirty years, the original finish has earned its character. This color does not rely on flashy effects to make a statement; it provides a bold, consistent look that stands out against the chrome and black trim of the era.

Technical Details

This is a solid finish, which means it lacks metallic flakes or pearl additives. While this makes it much easier to match than a complex metallic, it also means the paint is less forgiving of poor prep. Solid blues tend to highlight surface scratches and imperfections because there is no metallic sparkle to draw the eye away from the flat pigment. Your sanding and cleaning are the most important parts of the process because every ripple or nick in the metal will be visible under this deep blue coat.

Best Practices

Before you spray or dab GMC Bright Blue (check for code 42/WA9203), you need to shake it for 60 seconds to ensure the heavy pigment is fully mixed. You can usually find this code on the Service Parts Identification sticker located inside your glove box. To avoid sags or drips, apply several thin layers rather than one heavy coat. Always test the color on the included card to confirm the match before you apply it to your vehicle. Between each layer, allow enough drying time in a shaded Garage so the surface is no longer tacky. When applying, keep the container moving and maintain a consistent Nozzle distance to ensure a level finish across the repair area.
