Blast Metallic (Interior) (WA449A) Touch-Up Paint for Chevrolet

The Look

The 2018 Camaro was all about attitude, and this specific interior accent was designed to bring that high-energy exterior vibe right into the cockpit. Since it only appeared for a single model year, your cabin features a rare bit of Chevy history that separates it from the sea of standard black plastic. It provides a sharp, mechanical contrast against the upholstery, turning the dashboard and door trim into focal points. Because it is an interior finish, it hasn't faced the same sun-beating as your hood, but it still needs to be crisp to maintain that factory-fresh edge.

Technical Details

This is a true metallic finish, which means the secret to a good repair is flake control. If you apply the paint too heavily in one pass, those tiny metal particles will "swim" and clump together, creating dark, muddy-looking spots instead of a clean shimmer. Metallics are notorious for mottling-which is just a fancy way of saying it looks blotchy or striped-if the application is uneven. Keeping your layers thin is the only way to ensure the flakes lay flat and reflect light the way the engineers intended.

Best Practices

Before you spray or dab Chevrolet Blast Metallic (Interior) (check for code WA449A), you need to shake the container for at least sixty seconds. Those metallic flakes are heavy and love to settle at the bottom, so mixing is the most important step for a color match. You can find your official code on the silver Service Parts Identification sticker, usually located under the trunk carpet near the battery or spare tire well. Always test the color on the included card first to get a feel for the flow. When you move to the trim, keep the container moving at all times to prevent pooling, and give each layer plenty of drying time so the finish sets properly without any cloudiness.
