2020 Kenworth W900 Paint Color Codes & Touch-Up Guide

Keeping a heavy-duty legend like the 2020 Kenworth W900 looking its best requires regular maintenance, including touching up rock chips and scratches from the highway. Because the W900 is heavily customized for owner-operators and fleets, Kenworth offers a massive array of custom colors. However, several standard factory colors are incredibly common across the lineup.

If you are looking to restore the exterior of your rig, finding the exact factory paint code is the critical first step.

Quick reference

Below are the most common standard and popular factory colors for the 2020 Kenworth W900. Note: Because commercial trucks are often painted in custom fleet colors, always verify your specific paint code using your truck's VIN or paint label.

Color Name	Paint Code	Type (Solid / Metallic / Pearl)
Kenworth White	L0006EY / N0006	Solid
Viper Red	L0650EY / N0650	Solid
Black	L0001EY / N0001	Solid
Radiant Red	L0840EY	Pearl
Dark Blue	L0322EY	Metallic
Silver Metallic	L0758EY	Metallic
Bright Yellow	L0155EY	Solid
Omaha Orange	L0033EY	Solid

(If you are uncertain about your specific fleet or custom color, contact a local Kenworth dealer or commercial paint supplier with your VIN to confirm.)

Where to find your paint code

Unlike passenger cars that typically have a single unified B-pillar sticker, commercial trucks like the Kenworth W900 have specific locations for identification tags.

To find your paint code:

1. Driver’s Side Door Jamb or B-Pillar: Check the identification sticker located on the driver's side door latch post or the edge of the door itself.
2. Glove Box / Cab Storage: Look for a Line Setting Ticket or a Service Parts Identification label glued to the inside of the glove box or a side storage compartment. This sheet lists all the factory options and the specific paint formula codes used during assembly.
3. Under the Hood / Firewall: Occasionally, heavy-duty trucks feature a metal stamped plate on the firewall or cowl listing the basic trim and paint information.
4. Call the Dealer: Because PACCAR (Kenworth's parent company) uses sophisticated custom paint mixing systems (like Imron), the absolute best way to verify your W900’s paint code is to call a Kenworth dealership parts department with your 17-digit Vehicle Identification Number (VIN).

Best touch-up paint sources

Once you have your paint code, you’ll need a high-quality touch-up product that can withstand the rigors of the road.

• Dupli-Color: Great for basic, standard colors like gloss black or basic white. Available at most auto parts stores, they offer easy-to-use pens and spray cans.
• AutomotiveTouchup: One of the best online sources for custom-mixed automotive and commercial paints. They can mix exact aerosol spray cans, half-ounce bottles, or paint pens based on your Kenworth code.
• Tcoat Custom-Mix: An excellent option for specialty metallic and fleet colors that require a precise, durable match.
• Kenworth Dealer / Commercial Paint Supplier: For heavy-duty polyurethane paints (like Axalta Imron), going to a commercial supplier or the dealer is often required, especially for large areas or custom fleet color matching.

How to use touch-up paint

Fixing chips on that massive W900 hood or the aluminum cab requires patience. Follow these steps for the best results:

1. Clean the Area: Wash the damaged area with soap and water. Follow up with a wax and grease remover or rubbing alcohol to ensure no diesel film or road grime is left in the chip.
2. Apply Primer: If the chip goes down to bare fiberglass, aluminum, or steel, apply a small dab of automotive primer. Let it dry for 20–30 minutes.
3. Apply the Base Coat: Shake your paint well. Using a fine-tipped brush or a toothpick, dab the color into the chip. Apply in thin layers, waiting 15 minutes between coats until the paint is just below the surface of the surrounding clear coat.
4. Apply Clear Coat: Once the base coat is dry (usually after 30–60 minutes), apply the clear coat. The clear coat protects the color and provides the glossy finish. Allow it to cure fully for at least a few days before polishing.

Color matching tips for pearls and tri-coats

If your W900 features a premium color like Radiant Red Pearl, matching it can be tricky. Tri-coat paints require three layers: a solid base coat, a translucent pearl mid-coat, and a protective clear coat.

When touching up a tri-coat, apply the base coat first and let it dry. Then, apply the pearl mid-coat very sparingly. The more mid-coat you apply, the darker and more saturated the color will become. Test the process on a piece of scrap metal or cardboard first to figure out how many layers of pearl you need to match the factory hue. Always finish with a clear coat to bring out the depth of the metallic or pearl flakes.

For major bodywork, fiberglass hood repair, or full panel resprays that require professional blending, it's best to leave it to the pros. Find a trusted body shop on Repairius.
