Pontiac Impulse Metallic (24U/WA938J) Touch Up Paint

The Look

Your GTO carries a legacy, and this blue is the soul of that mid-2000s muscle revival. It is a deep, energetic shade that defines the modern goat. Since your car has been on the road for nearly twenty years, the original finish might have shifted slightly, but this pigment still holds its own against more modern colors. It was a rare choice back in the day, appearing on a small fraction of production models, which makes maintaining that factory glow even more important for the car's history and value.

Technical Details

This is a true metallic finish, which means the look relies entirely on how the tiny flakes sit in the paint. If you apply it too heavily in one spot, the flakes will cluster and create dark, blotchy patches known as mottling. You want the flakes to lay flat and even so they catch the light rather than looking like a bruise on the panel. Because these metallic particles are heavier than the paint itself, they tend to sink to the bottom of the container while sitting in your garage.

Best Practices

Before you spray or dab Pontiac Impulse Metallic (check for code 24U/WA938J), you need to shake it for 60 seconds. You can find your official code on the silver Service Parts identification sticker, usually located inside your glove box or under the spare tire cover. Once you are ready, test the color on the included card to ensure the shade matches your current aging. While applying, keep the container moving to avoid puddles and maintain a steady flow. Give each layer enough drying time before adding the next to build a depth that mimics the factory look.
