    Where To Find Your Paint Code

    To find the paint code for your 2020 GMC Sierra 1500, look for the "Service Parts Identification" sticker, which is usually located in the glove box. On this sticker, you'll find a list of three-character codes. Look for the code that begins with "WA" or "BC/CC U". The four-digit number that follows is your paint code. It will be listed next to a "U" for upper body color.

    Best Touch-up Paint Sources

    • Dupli-Color: Offers a wide range of colors for many domestic and import vehicles, including the 2020 GMC Sierra 1500. Their Scratch-Fix All-in-1 touch-up tool is a great option for small chips and scratches.
    • AutomotiveTouchup: This company can provide you with the exact color of your truck in a variety of formats, including paint pens, brush-in bottles, and aerosol cans.
    • T-Coat Custom Mix: For a perfect match, a local T-Coat custom mix paint supplier can use your truck's VIN to mix a batch of paint that will be an exact match to your truck's color.
    • Dealer: Your local GMC dealer can also provide you with touch-up paint that is a perfect match to your truck's color.

    How To Use Touch-Up Paint

    1. Clean the area: The first step is to clean the area you're going to be painting with a wax and grease remover.
    2. Primer: Next, apply a thin layer of primer to the area. This will help the paint adhere to the surface.
    3. Base Coat: Once the primer is dry, apply a thin layer of the base coat. This is the color coat.
    4. Clear Coat: Finally, apply a thin layer of clear coat. This will protect the paint and give it a glossy finish.

    Color Matching Tips For Pearls And Tri-Coats

    • Pearls: Pearl paints have a special effect that can be difficult to match. The best way to match a pearl paint is to use a spray-out card. A spray-out card is a small card that you can spray with the paint to see how it will look in different lighting conditions.
    • Tri-Coats: Tri-coat paints have three layers of paint: a base coat, a mid coat, and a clear coat. The mid coat is a translucent layer that gives the paint its special effect. The best way to match a tri-coat paint is to use a spray-out card. A spray-out card is a small card that you can spray with the paint to see how it will look in different lighting conditions.
