2020 Chevrolet Silverado 3500HD — Paint Color Codes

If you own a 2020 Chevrolet Silverado 3500HD and need to fix a rock chip, scratch, or minor scrape, getting the exact paint match is the first and most crucial step. Whether you have a rugged work truck in classic Summit White or a luxurious High Country in Iridescent Pearl Tricoat, using the correct factory paint code ensures a seamless repair. Below is your comprehensive guide to the 2020 Chevrolet Silverado 3500HD paint codes, where to find them, and how to apply touch-up paint effectively.

Quick reference

Here are the factory exterior colors offered for the 2020 Chevrolet Silverado 3500HD. General Motors often uses two formats for paint codes (a short RPO code and a longer WA code). We have included both for your convenience.

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

Where to find your paint code

Locating the paint code on a 2020 Chevrolet Silverado 3500HD is a bit different than older GM vehicles. While GM historically placed the Service Parts Identification (SPID) sticker in the glove box, newer models like the 2020 Silverado HD have transitioned to a modern label.

1. Check the B-Pillar: Open the driver’s side door and look at the B-pillar (the vertical frame behind the door) or the lower door jamb.
2. Look for the QR Code Label: You will find a silver or white Certification/Tire label that includes a QR code.
3. Read the Code: At the bottom of this label, look for a code starting with "BC/CC" (Basecoat/Clearcoat) followed by a "U" (Upper) and a four-digit alphanumeric code. For example, if your truck is Summit White, it will read U8624. The "WA" prefix (e.g., WA8624) is the industry standard for mixing this GM color.

Best touch-up paint sources

Once you have your exact WA paint code, you can source high-quality touch-up paint. Here are the most reliable options:

• Dupli-Color: A highly accessible option found at most local auto parts stores. They offer exact-match pens and aerosol cans for common GM colors like Summit White and Black. Perfect for quick, minor chip repairs.
• AutomotiveTouchup: Excellent for aerosol spray cans, paint pens, and larger ready-to-spray pints or quarts. They custom-mix the paint to order, ensuring high precision for metallic and tintcoat colors.
• Tcoat Custom-Mix: Another great online supplier that provides complete touch-up kits, including clear coats and blending solutions, ideal for getting professional results at home.
• Chevrolet Dealership (OEM): Your local GM dealership’s parts department sells official AC Delco touch-up paint pens. These feature an abrasive prep tip, the color base, and a clear coat applicator all in one handy tool.

How to use touch-up paint

Achieving a durable and invisible repair requires patience and proper technique. Follow these steps:

1. Clean the Area: Wash the damaged spot with soap and water, then wipe it down with a wax and grease remover or rubbing alcohol to ensure the paint adheres properly.
2. Apply Primer: If the scratch goes all the way down to bare metal or plastic, apply a light dab of automotive primer. Let it dry completely (usually 20–30 minutes).
3. Apply the Base Coat: Shake your paint pen or bottle vigorously. Apply the color in thin, light layers using a fine-tipped brush or toothpick for rock chips. Do not glob the paint. Allow 15–20 minutes of drying time between each coat until the color covers the primer entirely.
4. Apply Clear Coat: Once the final base coat is dry (wait at least 30 minutes), apply the clear coat. The clear coat provides the UV protection and glossy shine that matches the rest of your truck.

Color matching tips for pearls and tri-coats

If your 2020 Silverado 3500HD is painted in Iridescent Pearl Tricoat (G1W) or Cajun Red Tintcoat (GPJ), the repair process is more complex.

Tri-coats consist of three layers: a solid base color, a translucent pearl mid-coat, and a protective clear coat. When touching up a tri-coat:

• Practice first: Always test the layers on a scrap piece of metal or glossy cardboard.
• Control the mid-coat: The final color changes depending on how many layers of the pearl mid-coat you apply. Apply one layer at a time to your test card until it matches your truck, then replicate that exact number of coats on the vehicle.
• Blend carefully: Aerosol touch-ups on tri-coats are notoriously difficult to blend perfectly into the surrounding panels. For anything larger than a quarter-sized scratch, a professional blend is highly recommended.

For large scrapes, heavy panel damage, or complex tri-coat paint jobs that require a professional touch, don't leave it to chance. Find a trusted body shop on Repairius.
