    Where to Find Your Paint Code

    On a 2021 Kenworth T680, you'll typically find the paint code on the vehicle's identification plate. This plate is usually located on the driver's side door jamb or B-pillar. Look for a sticker or metal plate that contains information about your truck, including the VIN. The paint code is often labeled as "PAINT" or "PNT" and will be a combination of letters and numbers.

    Best Touch-up Paint Sources

    • Dupli-Color: Offers a wide range of popular colors in easy-to-use aerosol cans and touch-up pens. You can often find a match for your Kenworth's paint code, especially for common colors.
    • AutomotiveTouchup: Provides custom-mixed touch-up paint in various sizes, from small bottles to aerosol cans and larger quantities for spray guns. They can match your specific paint code for a precise color match.
    • Tcoat Custom-Mix: Specializes in creating custom-mixed paint to match your vehicle's exact color. This is a great option if you have a less common color or want to ensure a perfect match.
    • Dealer: Your Kenworth dealer can provide you with touch-up paint that is specifically formulated for your truck. This is often the most reliable way to get an exact match, but it may also be the most expensive option.

    How to Use Touch-up Paint

    1. Clean: Thoroughly clean the area to be repaired with soap and water, then use a wax and grease remover to ensure a clean surface.
    2. Primer: Apply a thin layer of primer to the prepared area. This will help the base coat adhere properly and will also prevent rust.
    3. Base Coat: Apply the base coat in thin, even layers, allowing each layer to dry before applying the next. Build up the color until it matches the surrounding paint.
    4. Clear Coat: Apply a clear coat to protect the base coat and give it a glossy finish. Apply in thin, even layers, just like the base coat.

    Color Matching Tips for Pearls and Tri-Coats

    Pearl and tri-coat paints can be more challenging to match than solid colors. Here are a few tips:

    • Test Panels: Before applying the paint to your truck, it's a good idea to test it on a small, inconspicuous area or a test panel to ensure a good match.
    • Blending: When applying the paint, blend it into the surrounding area to create a seamless transition between the old and new paint.
    • Professional Help: If you're not comfortable with the process or if you want to ensure a perfect match, it's best to seek professional help from a trusted body shop.
