Where to find your paint code

On the 2014 GMC Sierra 1500, the factory paint information is printed on the GM Service Parts Identification (SPID) label:

• Primary location: inside the glove box (white/black sticker packed with three‑character RPO codes).
• What to look for: the exterior color may appear as a three‑letter RPO such as GAZ (Summit White) or GBA (Onyx Black). You may also see a “BC/CC Uxxxx” notation paired with a WA number (for example, WA8624).
• If the label is missing: contact a GMC dealer’s parts department with your VIN; they can confirm the exact paint code/RPO. A professional paint supplier can also decode it from the VIN.

Tip: The certification label on the driver’s door jamb typically lists tire/weight info only and not the paint code for this model year—use the glove‑box SPID or your VIN for paint identification.

Best touch‑up paint sources

• Dupli‑Color: widely available pens, bottles, and aerosols for popular GM codes like GAZ (Summit White) and GBA (Onyx Black). Convenient for small chips and quick fixes.
• AutomotiveTouchup: mixes to your exact WA/RPO code in pens, bottles, and spray cans; also sells matched primer and clearcoat for more complete repairs.
• Tcoat custom‑mix: many local automotive paint jobbers and body shop supply stores can custom‑mix PPG/Axalta/BASF formulas to your GMC code (“WA” or RPO). Great for larger aerosol fills or spray‑gun quantities.
• GMC dealer: OEM touch‑up bottles for common colors; reliable for ensuring you get the correct factory code if you’re unsure.

Always confirm the code from your SPID label or VIN before ordering—GM color names can be similar across years but use different formulas.

How to use touch‑up paint

1. Clean and prep

• Wash the area, remove wax/grease with isopropyl alcohol or a dedicated prep solvent.
• Feather any loose edges. For rust, sand to clean metal and treat with rust converter if needed.

2. Prime (if needed)

• For bare metal or deep scratches, apply a compatible primer in light coats. Let it fully cure, then lightly wet‑sand (1000–1500 grit) to smooth.

3. Basecoat

• Shake the paint thoroughly. Apply multiple light coats, allowing flash time between passes. Stop when color coverage matches the surrounding area.

4. Clearcoat

• After the base flashes, apply clear in 2–3 light coats. This restores gloss and UV protection. Let it cure per product instructions.

5. Level and polish (optional)

• After full cure, lightly wet‑sand with 2000–3000 grit if needed, then compound and polish to blend the repair.

Color matching tips for pearls and tri‑coats

• Identify the system: White Diamond Tricoat (GBN/WA800J) is a true three‑stage (groundcoat + pearl midcoat + clear). Metallic colors like Quicksilver (GAN/WA636R) are two‑stage but still sensitive to technique.
• Do a spray‑out: Test your color on a card before the vehicle. For tri‑coats, count your mid‑coat passes—depth changes quickly with each coat.
• Control metallic orientation: Keep your spray distance and gun/valve pressure consistent. A “drop coat” (light, even final pass) can help metallics lay uniformly and avoid mottling.
• Blend when possible: On larger repairs, extend color lightly into adjacent panels and clear a wider area. Full‑panel edge‑to‑edge matches on pearls can be challenging without blending.
• Mind lighting: Judge color in natural daylight. Pearls can flip hue under different angles; a perfect shop‑light match can look off in sun.
• Temperature and humidity: Follow product flash/cure times closely—tri‑coats are sensitive to recoat windows.

If you’re unsure about a pearl/tri‑coat repair or lack blending space, a professional shop can save time and yield a factory‑level finish.
