2023 Chevrolet Silverado 2500HD — Paint Color Codes & Touch‑Up Guide

Quick reference

Note: The list above covers the most common factory colors for the 2023 Silverado 2500HD. Depending on trim and build date, a few limited or late‑availability colors may apply. If your color isn’t shown, confirm the exact code from your VIN with a Chevrolet dealer or a paint supplier before ordering.

Where to find your paint code

On 2023 Chevrolet Silverado 2500HD trucks, the paint code is usually found on a GM vehicle information label on the driver‑side B‑pillar (door jamb):

• Open the driver’s door and look on the vertical B‑pillar area for a white/silver GM label.
• This label may list "Paint" or show a "BC/CC" line with the WA number (for example, WA8624 for Summit White). You may also see the two‑ or three‑letter RPO code such as GAZ, GBA, etc.
• Some 2020+ GM trucks no longer carry the full Service Parts Identification (SPID) list in the glove box. If you do not see the paint code printed on the B‑pillar label, call a Chevrolet dealer with your VIN; they can pull the correct WA and RPO paint codes from GM systems.
• Alternate locations occasionally used: passenger‑side B‑pillar or, on some early builds, a glove box label. Always verify by VIN if you’re uncertain.

Tip: GM paint identifiers often appear in two formats. The RPO (e.g., GAZ) is the build code, while the WA/GM number (e.g., WA8624) is the formula code used by refinish suppliers.

Best touch‑up paint sources

• Dupli‑Color Perfect Match: Widely available aerosols and pens for common GM codes like GBA, GAZ, GAN, etc. Great for small panels, mirror caps, and bumpers.
• AutomotiveTouchup: Mix‑to‑code touch‑up bottles, pens, and aerosols, plus primer and clear. Good color accuracy and full system support.
• Tcoat custom‑mix: Professional custom mixing (pints/quarts) to your exact WA code for spray‑gun repairs or larger panels.
• Chevrolet dealer parts counter: OEM‑branded touch‑up pens and small bottles for popular colors; they can also confirm your code from the VIN.

Always provide both your color name and the WA or RPO code when ordering. If anything doesn’t match your door‑jamb label or VIN lookup, stop and re‑verify.

How to use touch‑up paint

1. Clean and decontaminate: Wash, degrease with isopropyl alcohol or wax/grease remover, and clay if needed. Remove rust with a fiberglass pen or sandpaper and treat bare metal.

2. Mask and prep: Feather any chipped edges with 600–800 grit. For larger spots, step to 1000–1500 grit to smooth the repair zone. Mask edges and trim.

3. Prime (as needed): Use an etch or epoxy primer on bare metal; a surfacer primer helps level the area. Sand smooth with 800–1000 grit after curing.

4. Basecoat: Shake thoroughly. Apply light, even passes, allowing flash time between coats. Metallics require very light final coats to keep the metallic flake evenly oriented.

5. Mid‑coat (tri‑coats only): For Iridescent Pearl Tricoat (G1W) and Cherry Red Tintcoat (GSK), apply the translucent mid‑coat in controlled, even passes. Color depth is controlled by the number of mid‑coat passes.

6. Clearcoat: Apply 2–3 wet coats with proper flash time. Let cure fully, then nib sand and polish if necessary (2000–3000 grit followed by compound/polish).

Color matching tips for pearls and tri‑coats

• Verify the exact code and variant: Some GM colors have multiple variants. Provide your supplier with the full WA code and your VIN if possible.
• Spray out a test card: Especially for G1W (Iridescent Pearl) and GSK (Cherry Red Tintcoat), make a small spray‑out card to judge coverage and mid‑coat passes before touching the truck.
• Control your film builds: Tri‑coats change appearance with each mid‑coat pass. Match the number of passes used on your spray‑out to the repair.
• Maintain metallic orientation: Keep the gun distance and angle consistent, and finish metallic basecoats with a light “drop coat” for even flake lay.
• Blend into adjacent panels: For best results on visible panels, blend base/mid into the next panel and clear to a break line. Spot repairs in the center of large panels can telegraph.
• Consider age and fade: Reds and pearls can shift slightly over time. If your spray‑out looks close but not perfect, ask your supplier about alternate variants or a tint‑on‑the‑fly adjustment.

When in doubt—especially on tri‑coats—having a professional body shop blend and clear the repair will yield the most invisible result.
