GMC Light Mesa Brown (37/WA9219) Touch Up Paint

The Look

If you are driving an S-Series or a G-Series van from the early nineties, you already know this color. It is the quintessential workhorse tan that defined the GMC lineup during the transition into the modern truck era. Whether it is on a Heavy Duty chassis or a suburban commuter, this shade was designed to look at home in the dirt. Because your vehicle has likely spent the last three decades facing the elements, the original finish has probably settled into a flatter, more muted version of itself. This is a grounded, no-nonsense earth tone that makes these boxy classics look purposeful rather than flashy.

Technical Details

Since this specific version of GMC Light Mesa Brown (always verify your code is 37/WA9219) is a solid finish rather than a metallic, you have a significant advantage. You do not have to worry about tiny metal flakes standing up on end or creating dark shadows if your technique isn't perfect. Solid colors are much more forgiving to apply with a brush or a pen, but they are honest-they show every bit of texture in the surface underneath. If your S-15 or G20 has deep scratches, the paint will fill them, but it won't hide a poor sanding job.

Best Practices

Before you begin, head to the passenger side and open the glove box. You should find the Service Parts Identification sticker there, which is where GMC tucked away the factory codes for this era. Once you are ready to work in your garage or a patch of shade, shake your container for a full minute to ensure the pigments are perfectly blended. Test the color on the included card to see how it looks against your weathered panels. When you start the repair, keep the container moving to avoid heavy buildup in one spot. If you are using a pen or brush for a rock chip, apply thin layers and give them plenty of drying time. It is always better to build the paint up slowly than to deal with a saggy glob of brown on your fender.
