2018 GMC Yukon Paint Codes

Quick reference

Where to find your paint code

For your 2018 GMC Yukon, the paint code can typically be found on a sticker located on the inside of the glove compartment door or on the service parts identification (SPID) label, which is often located on the underside of the trunk lid or in the spare tire well. It may also be on the regular certification sticker on the driver's side door jamb (B-pillar) or the edge of the driver's side door. The code will be a short alphanumeric sequence, often accompanied by a "BC/CC" designation, indicating "Basecoat/Clearcoat." For example, "41 / GBA" for Onyx Black.

Best touch-up paint sources

When it comes to touching up minor scratches or chips on your 2018 GMC Yukon, several reputable sources offer quality products:

• Dupli-Color: A widely available brand that you can find at most auto parts stores. They offer a good range of factory-matched colors in pens, bottles with brushes, and aerosol cans.
• AutomotiveTouchup: This online retailer specializes in custom-mixed touch-up paint precisely matched to your vehicle's factory code. They offer a more extensive selection of paint products, including primers, clear coats, and various application tools.
• Tcoat Custom-Mix: For a truly custom match, Tcoat can mix paint using your specific paint code, often providing excellent results for more complex colors.
• Dealership: Your local GMC dealership can also provide genuine OEM touch-up paint, ensuring a perfect match, especially for newer vehicles or unique colors.

How to use touch-up paint

For the best results, follow these general steps when applying touch-up paint:

1. Clean: Thoroughly clean the area to be touched up with soap and water, then dry it completely. You can also use a prep solvent to ensure all wax and contaminants are removed.
2. Prime (if necessary): For deeper scratches that expose bare metal or plastic, apply a thin layer of primer. Allow it to dry according to the product instructions.
3. Basecoat: Apply thin, even coats of your color-matched basecoat. Allow each coat to dry completely before applying the next. Build up the color gradually until it matches the surrounding paint.
4. Clearcoat: Once the basecoat is dry, apply several thin layers of clear coat to protect the paint and restore the shine. Again, allow adequate drying time between coats.
5. Finishing (optional): After the clearcoat has fully cured (this can take a few days), you can gently wet-sand with very fine-grit sandpaper (2000-3000 grit) to smooth out any imperfections, followed by a polishing compound to restore the gloss.

Color matching tips for pearls and tri-coats

Pearl and tri-coat paints, like the Crimson Red Tintcoat or White Frost Tricoat offered on the 2018 GMC Yukon, require a bit more care for successful color matching. These paints consist of multiple layers – typically a colored basecoat, a translucent pearl or tintcoat layer, and then a clear coat. The translucent layer is what gives these colors their depth and unique光泽.

When touching up these types of finishes, it's crucial to apply thin, even layers of each component. The amount of the pearl or tintcoat layer applied directly impacts the final color. Applying too much or too little can result in a noticeable difference. It's always a good idea to practice on a test card or an inconspicuous area first to get a feel for the application and how the layers build up the color.

If you are uncertain about a specific color or paint code, especially for more complex finishes, it's always best to verify the information with your VIN at a GMC dealership or a reputable automotive paint supplier. This ensures you get the exact match for your vehicle.
