2025 Isuzu NPR — Paint Color Codes & Touch‑Up Guide

Quick reference

Note: For the U.S. market, most 2025 Isuzu NPR trucks are delivered in Arc White from the factory. Fleet special‑order paints may exist but are not part of the standard retail order guide. Always verify the exact code against the vehicle label or through an Isuzu dealer using your VIN.

Where to find your paint code

Isuzu places the color information on identification labels on the cab. Look in these spots:

• Driver’s side door jamb/B‑pillar: Check the white certification/identification label and the adjacent Isuzu information label. One of these will list “Color,” “Body Color,” or a similar field with a short alphanumeric (often three characters). That is your paint code.
• Passenger‑side door opening: Some NPR cabs have a secondary Isuzu ID plate or sticker in the opposite jamb.
• Under‑hood or cowl area (varies by build plant/market): Certain plates list Model/Engine/Trans and Color/Trim. U.S. trucks more commonly show the code on the door jamb.
• Missing/illegible label: Your Isuzu Commercial Truck dealer can retrieve the correct color code from the VIN in their parts system. A reputable paint supplier can also decode it from the VIN.

Tip: The cab’s exterior color code applies to the body panels. The frame and chassis components are typically coated in a different industrial finish and do not use the same code.

Best touch‑up paint sources

• Dupli‑Color: Good for quick brush‑in bottles and aerosols. Enter your code or search “Isuzu Arc White” on their site or at auto parts stores.
• AutomotiveTouchup: Offers custom‑mixed bottles, pens, and aerosols by code, plus matched primer and clearcoat.
• Tcoat custom‑mix: Local or mail‑order custom mixers can formulate by your code and provide basecoat/clear or single‑stage options.
• Isuzu Commercial Truck dealer: Can confirm your code from the VIN and order OEM‑spec touch‑up bottles or direct you to an approved refinish brand.
• Local paint jobber (PPG, Axalta, BASF, Sherwin‑Williams Automotive): Can scan a good section of paint with a spectro for best match if code/variant is unclear.

How to use touch‑up paint

1. Clean and decontaminate: Wash the area with soap and water, then wipe with isopropyl alcohol or a wax/grease remover. Remove tar or iron fallout if present.
2. Prep the defect: Feather any chips or scratches with 800–1000‑grit; for bare metal or light rust, treat with rust converter and sand smooth. Mask edges if spraying.
3. Prime (as needed): Apply a thin etch or filler primer on bare metal. Let it cure, then sand lightly with 1000–1500‑grit until smooth.
4. Apply base color: Shake/mix thoroughly. Build several light coats, allowing flash time per the product label. Do not try to cover in one pass.
5. Clearcoat: Once the base flashes, apply 2–3 light coats of clear. For single‑stage formulations, you may skip clear if the product includes it—follow your paint supplier’s guidance.
6. Cure and finish: After full cure, level dust nibs with 2000–3000‑grit and lightly polish by hand. Avoid harsh washing or waxing for about 30 days.

Color matching tips for pearls and tri‑coats

• Know your paint system: Most NPR cabs come in a solid white, which is simpler to match than metallics/pearls. However, whites can vary by batch and may yellow or chalk over time, especially on commercial vehicles left outdoors.
• Verify the exact code and variant: Even with the right code, paint lines carry multiple “variant” formulas to match production differences and aging. Ask your supplier for a spray‑out card of the chosen variant before touching the truck.
• Spray‑out first: Always do a test panel (card or a concealed area) to confirm hue and brightness. Adjust gun distance and coat thickness to dial in coverage—over‑application can shift the shade on whites.
• Blend whenever possible: If you’re refinishing more than a chip, blend the color into the adjacent area and clear a larger section or full panel edge‑to‑edge. This reduces visible transitions, especially on large, flat cab panels.
• Consider single‑stage vs base/clear: Some commercial refinish systems use durable single‑stage urethanes. If your factory finish is base/clear, you’ll usually achieve a closer gloss and texture match using base/clear for the repair.
• Mind environmental wear: Compare your new paint to the sun‑exposed side you’re repairing, not to shaded areas. Oxidation can make a perfect formula look “off” unless you polish the surrounding paint.

If you’re unsure of the exact color, or the cab has been repainted by a prior owner or upfitter, confirm via VIN at the dealer or have a paint shop spectro‑match a clean section of the cab.
