2018 GMC Sierra 2500HD Paint Codes

Quick reference

Where to find your paint code

For your 2018 GMC Sierra 2500HD, you'll typically find the paint code located on a sticker in the glove compartment. Open the glove box, and look for a सफेद (Service Parts Identification) label. This label lists various codes and options for your truck, and among them, you'll find the paint code, often starting with "BC/CC" followed by a four-digit code (e.g., WA8624) or a two- or three-digit code (e.g., GAZ). In some cases, it might also be on the driver's side door jamb.

Best touch-up paint sources

When it comes to touching up minor scratches or chips on your 2018 GMC Sierra 2500HD, several reputable sources can provide a good match:

• Dupli-Color: A widely available brand that offers touch-up paint in pens, bottles, and aerosol cans. You can often find Dupli-Color products at automotive parts stores. Be sure to use their online lookup tool or check the store's catalog to ensure you get the exact match for your paint code.

• AutomotiveTouchup: This company specializes in custom-mixed automotive touch-up paint. They pride themselves on precise color matching and offer a variety of application options, including pens, bottles with brushes, and spray cans. They are an excellent choice for more challenging metallic or pearl finishes.

• Tcoat Custom-Mix: Tcoat is another great online option that custom-mixes paint to your vehicle's specific code. They often have a wider array of options for more complex paint types and can provide a very accurate match.

• Dealership: Your local GMC dealership can also supply OEM touch-up paint. While potentially more expensive, this is guaranteed to be an exact match and can be a good option for specific, hard-to-find colors.

How to use touch-up paint

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

1. Clean the area: Thoroughly clean the chipped or scratched area with soap and water, then dry it completely. You may want to use a degreaser or wax remover for optimal adhesion.

2. Apply primer (optional but recommended): For deeper chips that expose bare metal, apply a thin layer of primer. Allow it to dry completely according to the product instructions.

3. Apply base coat: Apply thin, even coats of your color-matched paint. Allow each coat to dry before applying the next. Build up the color gradually until it matches the surrounding paint.

4. Apply clear coat: Once the base coat is dry, apply a clear coat to protect the paint and give it a glossy finish. This step is crucial for durability and a seamless look.

Color matching tips for pearls and tri-coats

Pearl and tri-coat paints, like Crimson Red Tintcoat and White Frost Tricoat, are more complex than solid colors. They contain special pigments that create a multi-dimensional effect, which can make touch-ups trickier. Here are some tips:

• Layering is key: These paints achieve their depth through multiple layers. When touching up, you'll often apply a base color, then a mid-coat (the pearl or tinted clear layer), and finally a clear coat. Follow the product instructions carefully.

• Feathering: To blend the touch-up seamlessly, try to "feather" the edges of the new paint into the surrounding area. This means applying lighter coats at the very edge of the repair.

• Practice: If you're unsure, practice on a hidden area or a scrap piece of metal to get a feel for the application before working on a visible part of your truck.

• Professional help: For larger or more noticeable damage on pearl or tri-coat finishes, it's often best to consult with a professional body shop. They have the expertise and equipment to achieve a flawless repair.
