COLOR CODEWA408G - Sonoma Red Metallic (No Formula Available)GMC Touch-Up Paint

The Look

You are dealing with a short-run specialty from the 2014 GMC Sierra production year. This color is a deep, mature red that sits much heavier and darker than your standard fire-engine shades. Because it was essentially a single-year offering, it gives your truck a custom look that sets it apart from the sea of silver and black pickups on the road. Since your Sierra has likely spent a decade facing the elements, the original finish has developed a character that you need to respect when performing your touch-up.

Technical Details

This is a true metallic finish, which means the paint is packed with tiny flakes that provide its signature depth. These flakes are heavy and naturally want to sink to the bottom of the container. If you do not mix them thoroughly, the red will look too dark or flat, and you will see a noticeable line where the old paint meets the new. Before you spray or dab GMC Sonoma Red Metallic (No Formula Available) (check for code WA408G), you need to shake it for at least 60 seconds to get those flakes back into the suspension.

Best Practices

To confirm you have the right match, look inside your glove box for the silver Service Parts Identification sticker; the code should be listed near the bottom. Always test the color on the included card before you touch the truck. When you apply the paint, keep the container moving to ensure the metallic flakes distribute evenly across the repair area. Once the red is dry to the touch, you must apply a clear coat to protect the metal flakes from oxidizing and to bring out the deep glow that defines this specific shade. Work in a cool garage or the shade to prevent the paint from drying too fast.
