GMC Medium Brown Metallic (32/WA8866) Touch Up Paint

The Look

This color captures the exact moment GMC transitioned from the rugged squarebody C10-C30 Series into the sleeker, modern Sierra. It is a quintessential late-eighties earth tone that feels more sophisticated than the flat browns of the seventies. Because it was only active for a short window, it has become a hallmark for trucks that still carry their original character. Since your truck has likely spent decades out in the elements, you are dealing with a finish that has weathered the years, and this metallic provides the depth needed to bring that old-school heavy metal back to life.

Technical Details

This is a metallic finish, which means it relies on tiny flakes to catch the light and create depth. Metallics are notorious for mottling-those annoying dark patches or stripes that happen when the flakes do not lay down flat. If you hold your hand still for even a second, those flakes will bunch together and ruin the uniform look of the panel. Since these trucks have large, flat surfaces, any inconsistency in how the paint lands will be obvious once you step back into the light.

Best Practices

Before you spray or dab GMC Medium Brown Metallic (check for code 32/WA8866), you need to shake it for at least 60 seconds to get those heavy metallic flakes off the bottom. You can usually find your official color code on the service parts identification sticker located inside the glove box. To avoid dark spots, keep the container moving in steady, overlapping passes and never stop your motion while the paint is flowing. Test the color on the included card first to ensure the flakes are mixing properly. Work in the garage or the shade to prevent the surface from getting too hot, and give each layer enough drying time so the finish sets hard and clear.
