Where to find GMC color code

How to Find Your GMC's Color Code

GMC placed paint codes in many different locations, making them difficult to find, and GM did not standardize the color plate location across makes and models. Codes are often found in the glove box or the spare tire well; otherwise they could be elsewhere. Typical format: 51/WA316N, usually preceded by BC/CC (e.g., BC/CC 51 or BC/CC 316N). Two-tone entries may use U or L for Upper or Lower (e.g., BC/CC U316N or BC/CC L316N).

Your Paint Color Profile

Dark Mesa Brown Metallic

The Look

This color is a time capsule of the era when GMC redefined the American road trip. If you are working on a G10-G30 Series van or a classic S-Series pickup, you are dealing with one of the most honest, earthy tones of the late eighties. It is a deep, grounded shade that was designed to look just as good pulling a trailer as it did parked at a campsite. Because it is an earth tone, it is incredibly forgiving when it comes to hiding road dust and light grime, making it a practical choice for vehicles that actually see the outdoors. Since your GMC has likely been on the road for over thirty years, the original finish has probably mellowed, so your new touch-up will bring back a richness the sun has slowly stolen away.

Technical Details

This is a true metallic finish, which means the paint is packed with tiny flakes that provide its signature depth. Metallics are the most common victims of mottling-those annoying dark spots or "tiger stripes" that happen when the flakes don't lay down evenly. If the flakes settle at the bottom of the container or pool in one spot on the panel, the color will look inconsistent. You want those metallic particles to float evenly in the finish so they catch the light the same way across the whole repair. This isn't just about the color; it is about managing the texture of the light itself.

Best Practices

Before you spray or dab GMC Dark Mesa Brown Metallic (check for code 40/WA9202), you need to shake the container for at least sixty seconds to wake up those heavy metallic flakes. You can usually find your paint code on the Service Parts Identification sticker inside the glove box or, if you have a full-size van, check the pillar near the driver's door. To get the best result, always test the color on the included card to see how the flakes settle before touching your vehicle. Work in the shade to ensure a consistent drying time between coats. Whether you are using a nozzle or a brush, keep the container moving in steady, even passes to prevent the pigments from bunching up.

Will absolutely order from this company again.

After ordering touch-up paint from Lexus I was still waiting for it a month later. If they'd told me upfront it would take that long I wouldn't have ordered in the first place. Paint Scratch was recommended by a friend who restores cars. Easy ordering, fair price and fast shipping. The color match is great especially considering my car is a 2012. Will absolutely order from this company again. Reason I chose this business: Lexus collision repair and a local collision repair. Will use paint less dent removal and touch up chipped paint myself. Reason I chose this product: Spouse sideswiped passenger side of car while backing out of garage. Mostly plastic transfer from his wheel well trim but pressure creased and cracked the paint causing a bare strip 1/8 wide x 4” long below door handle. Scratches on door handle and a few small chips on both doors.

Simply the best custom mixed paint in spray cans

Used Paint Scratch metallic custom mixed spray cans paint on a hood panel with excellent coverage and texture over the surface. Metallic paint can be very unforgiving out of a spray can, sputtering pigmentation dots on the panel being sprayed and thus ruining the paint job. No such issues with Paint Scratch custom mixed metallic paint spray cans. Paint sprayed strong and evenly till the last drop of paint in the can. Shipping time was faster than expected. Reason I chose this business: Having tried other brands of custom mixed metallic paint with terrible results, sputtering pigmentation tint dots from the spray nozzle in spite of vigorously shaking of can prior to application and loss of propellant rendering the lower fifth of the can's paint useless, Paint Scratch custom mixed metallic paint sprays out beautifully and strong all the way to the last gram of paint in the can. Simply the best custom mixed paint in spray cans for automotive restoration. Thank you Paint Scratch.

Frequently Asked Questions

How do I find my vehicle’s paint code?

Your paint code is usually found in the driver’s door jamb, trunk, or under the hood. See our GMC Paint Code Guide for detailed instructions.

Will this paint match my car?

Because your GMC is older or uncommon, the most accurate option is custom matching where you mail in a small painted part for a hand match. Our paint technicians usually do a great job matching GMC color code '40/WA9202' but a perfect match cannot be guaranteed.

Do I need primer and clearcoat?

While primer is recommended on bare metal or plastic, clearcoat is essential: it protects the basecoat and restores factory gloss.

How long does shipping take?

Orders are mixed fresh and ship within 3–5 business days. Delivery takes 2–14 days depending on location.

Which touch up product should I choose?

 It depends on the size of the damage:

  • Paint Pen (½ oz) – Best for very small chips and fine scratches.
  • Brush Bottle (2 oz) – Great for medium chips or scratches up to the size of a quarter.
  • Spray Can – Ideal for larger areas and panels.
  • Professional Sizes (Pint, Quart, Gallon) – Designed for full panel and vehicle resprays using spray equipment.

Not sure? If it’s just rock chips or small scratches, start with a Paint Pen.

Can I return my order?

Yes! If there’s a color match issue, we’ll replace the product or give you your money back. You also can return unopened, non-custom accessories for a full refund.

How long will the paint last in storage?

Paint pens and bottles last about a year if stored cool and dry. Spray cans can last several years if the nozzle is cleaned.
