COLOR CODEG48 - GalacticaGMC Touch-Up Paint

The Look

Your Sierra or Yukon carries a massive presence, and this shade adds a layer of modern sophistication to that heavy-duty frame. It is a deep, dark tone that feels more like a custom finish than a standard factory option. Since your truck has likely been on the road since 2023, it still maintains a current and high-end appearance compared to the flatter, older greys and blues of the past decade.

Technical Details

This is a metallic finish, meaning the paint is packed with fine particles that catch the light to create depth. Metallic paints are sensitive to the thickness of each layer. If the paint goes on too heavy, the flakes sink and create dark spots or stripes, often called mottling. To get that factory look, you need a steady, even flow so the metallic bits sit correctly on the surface and reflect light uniformly across the repair area.

Best Practices

Before you spray or dab GMC Galactica (check for code G48), you need to shake the container for at least a full minute to get those metallic flakes moving. You can find your specific code on the silver Service Parts Identification sticker, which is usually inside your glove box or on the driver's side door jamb. Always test the color on the included card before you touch the vehicle to see how the flakes settle. When you start, keep the container moving across the area to avoid building up too much paint in one spot, and allow plenty of drying time between each light coat.
