2019 GMC Acadia — Paint Color Codes & Touch‑Up Guide

Quick reference

Notes:

• These are GMC/GM RPO paint codes for the 2019 Acadia. Many paint suppliers also reference the long GM “WA” code that corresponds to the RPO. If you need the WA number, confirm it from your vehicle’s label or by VIN at a dealer/paint supplier.
• Some late‑availability or limited colors may exist on specific trims or packages. If your color name isn’t listed above, verify by VIN.

Where to find your paint code

GM places the paint information on the Service Parts Identification (SPID) label. On the 2019 GMC Acadia, check these spots:

• Glove box: Open the glove compartment and look for a white/black SPID label printed with dozens of three‑character codes (RPOs). Your exterior paint appears as a code like GAZ, GAN, G9K, etc.
• Rear cargo area: Lift the cargo floor panel and inspect near the spare/jack storage or side trim for the SPID label (varies by build plant).
• Driver’s door jamb/B‑pillar: The certification label may list paint information or a QR code; however, the definitive paint RPO is on the SPID label.
• Can’t find it? A GMC dealer can pull the paint code from your VIN, and most paint suppliers can do the same.

How to read it: On the SPID label, look for your exterior paint RPO (examples above). Some labels also show a “WA” number or a “BC/CC U” notation; give either the RPO or WA code to your paint source.

Best touch‑up paint sources

• Dupli‑Color: Convenient pens and small bottles for popular GM colors; good for chips and small scratches.
• AutomotiveTouchup: Mix‑to‑code options (bottles, pens, aerosol) using your RPO/WA code; helpful when your color isn’t stocked retail.
• Tcoat custom‑mix: Local or online jobber can custom‑mix by code and make aerosol or fill touch‑up pens for better match control.
• GMC dealer parts: OEM‑branded touch‑up pens for common colors; availability varies.

Tip: Always supply your exact paint code (and VIN if possible). For tri‑coats like White Frost (GP5) and Red Quartz (GPJ), order the full system (ground/base, midcoat, and clear).

How to use touch‑up paint

1. Clean and prep: Wash, then wipe with isopropyl alcohol or wax/grease remover. De‑rust any exposed metal and lightly sand the chip edge (1000–1500 grit) to feather.
2. Prime bare metal: Apply a thin etch or filler primer to any exposed metal; allow to dry, then scuff lightly.
3. Apply color:
   • Solid/metallic: Shake well. Apply very thin coats, letting each flash per product directions. For pens, dab—don’t drag—the tip.
   • Tri‑coats (pearls/tintcoats): First apply the ground/base color. After it flashes, apply the midcoat (pearl/tint) in very light passes.
4. Clearcoat: Seal with a compatible clear after the color has flashed. Two to three light coats typically give best gloss.
5. Level and polish (optional): After curing, nib with 2000–3000 grit wet sandpaper and polish to blend. Avoid aggressive sanding on edges/body lines.

Color matching tips for pearls and tri‑coats

• Confirm your exact code: Colors like White Frost (GP5) and Red Quartz (GPJ) are tri‑coats; even small application differences change the look. Verify code by VIN if in doubt.
• Use a spray‑out card: For aerosols or airbrush, make a test panel to dial in midcoat passes before touching the vehicle.
• Control film build: The midcoat controls depth—too many passes will darken/saturate; too few will look washed‑out. Keep passes even and consistent.
• Mind viewing angle and light: Pearls “flip” under different angles. Judge match outdoors in daylight as well as under shop lighting.
• Blend when possible: For larger scratches, blend into the surrounding area rather than ending the repair abruptly; this hides slight shade differences.
• Account for aging: Older finishes may be slightly faded. A custom‑tinted mix (jobber/paint store) can compensate better than off‑the‑shelf.

If your Acadia’s color isn’t in the table above or your build appears to have a special/late color, confirm the paint code by VIN with a GMC dealer or a professional paint supplier before ordering.
