2014 GMC Sierra 2500HD Paint Color Codes & Touch-Up Guide

Keeping your heavy-duty truck looking its best requires having the exact right paint for rock chips, scratches, and scrapes. If you need to touch up your 2014 GMC Sierra 2500HD, finding the correct factory paint code is the first and most important step.

Below is your comprehensive guide to the 2014 GMC Sierra 2500HD paint colors, where to find your vehicle’s specific code, and how to successfully apply touch-up paint for a flawless finish.

Quick reference

GM typically uses two formats for their paint codes: a two-letter/number RPO code (like GAZ) and a "WA" code (like WA8624). Both refer to the exact same paint color. Here are the common factory colors offered for the 2014 GMC Sierra 2500HD:

Color Name	Paint Code (WA / RPO)	Type (Solid / Metallic / Pearl)
Summit White	WA8624 / GAZ	Solid
Onyx Black	WA8555 / GBA	Solid
Fire Red	WA9006 / 74	Solid
Quicksilver Metallic	WA136X / GAN	Metallic
Iridium Metallic	WA121V / GXG	Metallic
Sonoma Red Metallic	WA138X / G7U	Metallic
Heritage Blue Metallic	WA132X / GUX	Metallic
Bronze Alloy Metallic	WA105V / GWX	Metallic
Mocha Steel Metallic	WA706S / GHA	Metallic
Cobalt Blue Metallic	WA722J / GWY	Metallic

Note: If you are uncertain about your specific color, always confirm via your VIN at a local GM dealer or through your paint supplier.

Where to find your paint code

Unlike many other vehicle brands that place the paint code on the driver's side door jamb, General Motors vehicles from this era usually have it hidden away.

For the 2014 GMC Sierra 2500HD, you will find the paint code on the Service Parts Identification (SPID) sticker located inside the glove box.

1. Open the glove box and look for a silver or white sticker covered in dozens of three-character RPO (Regular Production Option) codes.
2. Look at the very bottom line of the sticker.
3. You will typically see "BC/CC" (which stands for Basecoat/Clearcoat), followed by a "U" (for Upper color) and a 4-digit number or alphanumeric code.
4. For example, if it says U 8624, your paint code is WA8624 (Summit White).

If the glove box sticker is missing or illegible, you can call any GM dealership parts department, give them your Vehicle Identification Number (VIN), and they can look up your exact factory paint code.

Best touch-up paint sources

Once you have your paint code, it's time to source your paint. Here are the best options for acquiring a perfect match:

• AutomotiveTouchup: Highly recommended for older trucks. They custom-mix paint based on your exact WA code, providing options ranging from paint pens to aerosol spray cans and ready-to-spray pints for spray guns.
• Dupli-Color: A staple in auto parts stores. Dupli-Color’s "Perfect Match" line offers readily available aerosol cans and 2-in-1 scratch fix pens for the most popular GM colors like Summit White and Onyx Black.
• Tcoat Custom-Mix: Great for specialized color matching, especially if your truck has seen significant sun fading over the years.
• Your Local GM Dealership: An AC Delco touch-up pen from the parts counter guarantees an OEM color match, though they usually only supply small pens or bottles, not aerosol cans.

How to use touch-up paint

For a durable, invisible repair, preparation and patience are key. Follow these steps:

1. Clean: Wash the affected area thoroughly with dish soap and water. Follow up with a wax and grease remover or rubbing alcohol to ensure no contaminants remain.
2. Primer: If the scratch goes all the way down to bare metal or plastic, apply a light coat of automotive primer. Let it dry completely.
3. Base Coat: Shake your color base coat well. Apply it in very light, thin layers. Allow 10 to 15 minutes of drying time between each coat. Repeat until the primer is completely covered and the color matches the surrounding area.
4. Clear Coat: The base coat will usually dry with a dull, matte finish. The clear coat provides the UV protection and the glossy shine. Apply 2-3 thin layers of clear coat over the dried base coat, allowing drying time between layers.

Color matching tips for pearls and tri-coats

While the 2014 Sierra 2500HD primary colors are solids and standard metallics, GM occasionally utilizes complex pearl or tri-coat finishes on premium trims like the Denali (such as White Diamond Tricoat).

• Tri-coats require three steps: A base color layer, a translucent pearl mid-coat, and a clear coat.
• Practice first: Always use a test card. The final color of a tri-coat depends heavily on how many layers of the pearl mid-coat you apply. Too few, and it looks flat; too many, and it becomes too dark or yellow.
• Blend metallics: Metallic paints (like Quicksilver) have tiny metal flakes. Spraying too heavily can cause the flakes to pool together, creating dark spots. Always use light, sweeping motions.

For extensive paint damage, large panels, or complex tri-coat blending, DIY touch-up might not cut it. Find a trusted body shop on Repairius to restore your heavy-duty truck to showroom condition.
