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

Medium Green

The Look

This color is the hallmark of a truck that earned its keep. It is a grounded, medium-toned green that defined the 1970 GMC lineup, leaning into a deep, earthy hue that feels more at home on a timber road than a showroom floor. It does not try to be flashy. Instead, it offers a sense of permanence. Since your truck has likely spent over fifty years in the sun and rain, the original finish has almost certainly matured into a softer version of itself. This green is a piece of heritage that represents an era when GMC trucks were built as tools first and vehicles second.

Technical Details

You are working with a solid finish, which is excellent news for a repair. Because there are no metallic flakes or pearls in the mix, you do not have to worry about the pigment settling unevenly or creating stripes across your panel. This makes the color very forgiving for small repairs. However, solid greens are very honest. They show every surface ripple and dent because there is no shimmer to distract the eye. If your repair involves a clear coat, keep in mind that the clear will deepen the green and add a level of gloss that your original paint might have lost over the decades.

Best Practices

You will generally find your factory information on the Service Parts Identification decal located inside the glove box. Before you begin applying GMC Medium Green (paint code 518 (1970)), you must shake the container for at least sixty seconds to fully integrate the heavy pigments. Test the color on the included card to see how well it matches your specific truck. When you are ready to apply, keep the container moving to ensure an even coat. Focus on thin layers and give the paint plenty of drying time between applications to prevent the green from sagging or running.

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 '518 (1970)' 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.
