2015 Chevrolet Silverado 3500HD — Paint Color Codes

When it comes to maintaining the rugged good looks of your 2015 Chevrolet Silverado 3500HD, keeping the exterior free of chips and scratches is essential. Whether you use your heavy-duty truck for towing, worksite duties, or everyday driving, minor paint damage is inevitable. Finding the exact factory paint code is the first step toward a seamless repair. Below is the complete guide to 2015 Silverado 3500HD paint codes, where to find them, and how to apply touch-up paint effectively.

Quick reference

Here are the factory paint colors offered for the 2015 Chevrolet Silverado 3500HD. Please note that General Motors often uses both an RPO (Regular Production Option) code (like GAZ) and a WA code (like WA8624) to identify paint colors. The WA code is the most precise identifier for mixing paint.

Color Name	Paint Code (RPO / WA)	Type
Summit White	GAZ / WA8624	Solid
Black	GBA / WA8555	Solid
Silver Ice Metallic	GAN / WA177B	Metallic
Victory Red	PRK / WA9260	Solid
Deep Ocean Blue Metallic	G1K / WA409Y	Metallic
Brownstone Metallic	GWX / WA105V	Metallic
Tungsten Metallic	GXG / WA121V	Metallic
Rainforest Green Metallic	G7J / WA138X	Metallic
Autumn Bronze Metallic	G1W / WA132X	Metallic
White Diamond Tricoat	G1W / WA800J	Pearl / Tri-coat

Note: If you are uncertain about your specific color variant, always confirm via your VIN at a local dealership or with your chosen paint supplier.

Where to find your paint code

Unlike many other vehicle manufacturers that place the paint code solely on the driver's side door jamb, General Motors vehicles from this era use a "Service Parts Identification" (SPID) label.

For the 2015 Chevrolet Silverado 3500HD, you will usually find this silver or white sticker located inside the glove box. Look for a label filled with dozens of three-character alphanumeric codes (these are your truck's RPO codes). At the very bottom of this sticker, you will see a code preceded by "BC/CC" (Basecoat/Clearcoat) and "U" (Upper) or "L" (Lower). The four-character code starting with "WA" (e.g., WA8624) is your exact paint code.

If the glove box sticker is missing or unreadable, a GM dealership can run your Vehicle Identification Number (VIN) to give you the exact factory WA code.

Best touch-up paint sources

Getting the right paint is crucial for a discreet repair. Here are the most reliable sources for 2015 Silverado 3500HD touch-up paint:

• Dealership: Your local Chevy dealer parts department will sell OEM AC Delco touch-up pens and small brush bottles. This is the safest bet for standard solids and metallics.
• Dupli-Color: Available at almost any auto parts store, Dupli-Color offers exact-match aerosol cans and 2-in-1 scratch fix pens specifically formulated to match GM WA codes.
• AutomotiveTouchup: For larger jobs, AutomotiveTouchup provides custom-mixed paints in bottles, spray cans, and ready-to-spray pints/quarts for spray guns. Their color-matching accuracy is exceptional.
• Tcoat Custom-Mix: Another great online retailer that custom mixes exact factory colors based on your specific WA code, ensuring fresh, high-quality basecoat.

How to use touch-up paint

Achieving a professional-looking result requires patience and the correct process:

1. Clean: Wash the damaged area thoroughly. Use a wax and grease remover or rubbing alcohol to remove any contaminants, oils, or old wax from the scratch.
2. Primer: If the scratch or chip goes all the way down to the bare metal, apply a light dab of automotive primer. Let it dry completely.
3. Base: Shake your paint pen or bottle vigorously. Apply the color basecoat in thin, light layers. Do not try to fill the chip in one go. Allow 15-20 minutes of drying time between each coat until the color is opaque and level with the surrounding area.
4. Clear: Factory paint jobs are a two-stage system. Once the basecoat is completely dry (usually after 30-60 minutes), apply the clearcoat. The clearcoat provides the glossy finish and UV protection.

Color matching tips for pearls and tri-coats

If your Silverado is painted in a complex color like White Diamond Tricoat (WA800J), touch-up repairs require a bit more finesse.

Tri-coats consist of three layers: a solid base color, a translucent pearl mid-coat, and a protective clearcoat. When buying touch-up paint for a tri-coat, you will receive two separate color bottles (base and pearl) plus the clearcoat.

To blend successfully, apply the basecoat until the primer is hidden. Then, apply the pearl mid-coat in incredibly light, sheer layers. Check the match in direct sunlight after each pearl layer—the more pearl you add, the darker and more yellow/shimmery the spot will become. Once it matches, seal it with clearcoat. Due to the complexity of light reflection, tri-coats are notoriously difficult to match perfectly in a driveway setting.
