Best Touch-up Paint Sources
- Dupli-Color: Dupli-Color offers a wide range of perfectly matched touch-up paints for your GMC Sierra. You can find their products at most auto parts stores.
- AutomotiveTouchup: AutomotiveTouchup is an online retailer that specializes in custom-mixed touch-up paint. They can mix a batch of paint to match your truck's exact color code.
- Tcoat Custom-Mix: Tcoat is another online retailer that offers custom-mixed touch-up paint. They also have a variety of applicators to help you get a professional-looking finish.
- GMC Dealership: Your local GMC dealership can also provide you with touch-up paint. This is a good option if you want to be sure that you are getting the exact same paint that was used on your truck at the factory.
How to Use Touch-up Paint
- Clean the area: The first step is to clean the area that you are going to be painting. Use a wax and grease remover to remove any dirt, oil, or other contaminants.
- Primer: If the scratch or chip is deep, you may need to apply a primer first. This will help the paint adhere to the surface and prevent it from chipping or peeling.
- Base coat: Once the primer is dry, you can apply the base coat. Apply a thin, even coat of paint and let it dry completely.
- Clear coat: After the base coat is dry, you can apply a clear coat. This will protect the paint and give it a glossy finish.
Color Matching Tips for Pearls and Tri-Coats
Pearl and tri-coat paints can be tricky to match. This is because they contain small flakes of mica that reflect light in different ways. To get a perfect match, it is important to use a touch-up paint that is specifically designed for pearl or tri-coat paints.
Here are a few tips for matching pearl and tri-coat paints:
- Use a spray-out card: A spray-out card is a small piece of paper that you can use to test the color of the paint before you apply it to your truck. This will help you to make sure that the color is a perfect match.
- Apply the paint in thin, even coats: When you are applying the paint, be sure to apply it in thin, even coats. This will help to prevent the paint from looking blotchy.
- Use a blending solvent: A blending solvent can be used to help the new paint blend in with the old paint. This will help to create a seamless repair.
