GMC Heavy Duty Touch Up Paint (20 OEM Colors)

The Color Breakdown

GMC really went for it with the Heavy Duty lineup, recording a solid 20 colors that range from "work site staple" to "weekend warrior." You've got the classics like Wheatland Yellow and Tangier Orange for those who want their truck visible from space, alongside more sophisticated tones like Light Slate Metallic and Woodland Green. Whether you're driving a rolling shadow in Black 200 Gloss or a shimmering mountain in Silver Metallic, these trucks were built to look as big as they pull.

What to Watch For

Before you start dabbing, we need to find your "birth certificate"-the paint code. On a GMC Heavy Duty, this is almost always a game of hide-and-seek in the glove box. Look for a silver or white sticker labeled "Service Parts Identification" and find the code next to "BC/CC" (it usually starts with a "U" or "WA").

Now, for the reality check: these big rigs have a lot of surface area for the elements to attack. It's common to see the paint getting a bit "sunburnt" (peeling) on the roof or hood, and the heavy-duty door handles have a habit of rubbing the paint raw until it starts to flake. If you see a chip, catch it early! These paints can be a little thin on the rocker panels, so keep an eye on those high-traffic zones where road debris likes to party.

Driveway Repair Tip

Since so many GMC shades are metallic-like that Blue Metallic or Gray Metallic-patience is your best tool. Those tiny metallic flakes are like glitter at a toddler's birthday party; they want to clump together. Shake your touch-up bottle or spray can for a full 60 seconds (set a timer!) to wake up the sparkles.

When applying, thin layers are your best friend. If you try to fill a deep chip in one "blob," the metallic flakes will sink to the bottom and the color will look too dark. Instead, think of it like painting a fingernail: apply a tiny bit, let it dry for 20 minutes, and then come back for a second pass. It requires patience, but your hood will thank you for not giving it a "polka-dot" look.
