Painting your car's fender flares is a great way to customize your vehicle's look. Fender flares are usually matte black, but you can paint them to match your car's body colour or choose a contrasting shade to make them stand out. Before painting, it's important to clean the surface with a degreaser and wipe it down with a tack cloth to ensure the paint adheres properly. You can then apply a coat of primer and your chosen paint. If you're painting plastic fender flares, you may need to use an adhesion promoter and sand the surface to ensure the paint sticks.

What You'll Learn
Use paint intended for plastics
Painting your fender flares is a simple process, but it requires the right tools and preparation. One of the most important things to consider when painting plastic fender flares is the type of paint you use. Using paint intended for plastics is crucial to achieving a durable and long-lasting finish.
When selecting paint for your plastic fender flares, opt for enamel or polyurethane automotive paint. These types of paint are designed specifically for use on automotive surfaces, including plastic. They offer better adhesion and flexibility than traditional spray paints, resulting in a smoother and more durable finish. Automotive paint can be found at most auto parts stores or online.
Additionally, when painting plastic fender flares, it is essential to prepare the surface properly. This includes cleaning the flares with a high-quality degreaser and then sanding them to create a smooth base for the paint to adhere to. Once the flares are prepared, you can apply a primer specifically designed for plastic surfaces, such as a polypropylene primer.
After priming, you can apply the automotive paint using a spray can or a paint gun. Be sure to follow the manufacturer's instructions for the best results. It is also important to work in a well-ventilated area and wear a respirator when spraying paint. Allow the paint to dry completely before handling the flares or reinstalling them on your vehicle.
By using paint intended for plastics and following the proper preparation and application techniques, you can achieve a high-quality and long-lasting finish on your black plastic fender flares.

Sand down the fender flares
Sanding down the fender flares is an important step in the painting process. It helps to remove any existing texture on the flares and creates a smooth surface for the paint to adhere to. This step is especially important if you are painting textured flares, as it ensures that the paint will go on evenly and produce a smooth, professional-looking finish.
Before you start sanding, it is crucial to clean the surface of the fender flares thoroughly. Use a high-quality degreaser to remove any dirt, grease, or grime that may be present. Once the flares are clean, dry them off with a tack rag or a clean cloth to remove any remaining dust or debris.
When sanding, it is recommended to start with a medium grit sandpaper, such as 200-grit. This will help remove any imperfections, rough spots, or scratches on the surface of the flares. Use steady, consistent strokes and apply light to moderate pressure. Pay extra attention to any damaged areas, such as deep scratches or dents, and focus your sanding efforts on those spots. If there are dents, you can use a heat gun to push them out before sanding.
After the initial sanding with medium grit sandpaper, it's time to switch to a finer grit. Opt for a 2000-grit scotch brite pad or sandpaper for this step. This finer grit will help smooth out the surface even further and create a more refined finish. Again, use gentle pressure and consistent strokes, ensuring that you cover the entire surface of the flares.
Once you have finished sanding, it is crucial to wipe down the fender flares with a tack cloth or a clean, soft cloth. This step is essential to remove any remaining dust or debris that may have been generated during the sanding process. Make sure to wipe down all surfaces, including the inner and outer sides of the flares, to ensure that no dust particles are left behind, as they can cause issues with paint adhesion and create an uneven finish.
After sanding, your fender flares should feel smooth to the touch, with any imperfections or scratches significantly reduced or eliminated. This process prepares the surface for the application of a primer, which will help the paint adhere better and create a more durable and long-lasting finish.

Use an adhesion promoter
Painting fender flares is a tedious process that requires several steps, professional-grade materials, and a clean workspace. It is important to prep your plastic fender flares before painting them. Start by cleaning the flares with a suitable cleaner, such as dish soap and water, to remove any dirt, oil, or contaminants. You can also use a detergent soap wash followed by a degreaser to ensure the surface is free of any impurities. Once the flares are clean, dry them with a microfiber cloth.
The next step is to sand the surface of the flares to create a rougher texture that paint will adhere to better. Use 200-grit sandpaper or a fine-grit sanding sponge to sand the flares, removing any scratches, imperfections, or rough spots. If there are dents, use a heat gun to push them out, and then sand the area to level it. Be sure to cover every surface that will be painted, transforming the semi-gloss sheen of the factory flares to a uniform, matte finish. After sanding, wipe the flares with a tack cloth to remove any dust.
Now, it's time to treat the surface of the flares with an adhesion promoter. Adhesion promoters help the paint adhere better to the plastic surface and can be purchased from auto parts stores or professional paint shops. Follow the manufacturer's instructions for applying the adhesion promoter, and be sure to mix the product thoroughly before use. Allow the adhesion promoter to dry completely before proceeding to the next step.
Once the adhesion promoter is dry, you can apply a primer to the flares. It is recommended to use a solvent-based primer and paint products for better adhesion and to prevent peeling or crinkling. Apply two coats of primer, allowing each coat to dry before applying the next. Lightly sand the primed surfaces with fine-grain sandpaper, such as 2000-grit, to smooth them down, and then wipe the surface with a tack cloth to remove any dust.
Finally, you are ready to apply the paint to the fender flares. Use slow, sweeping motions when spraying the paint, and apply two to three thin, even coats to avoid runs in the paint. Allow each coat to dry for approximately 30 minutes, or refer to the manufacturer's guidelines for exact drying times. Once the paint is dry, you can install the fender flares, but be sure to wait a full 24 hours before installation to ensure the paint has fully hardened.

Apply primer
Painting fender flares can be a great way to customize your car and give it a unique look. If you're planning to paint black plastic fender flares, it's important to follow the proper steps to ensure a smooth and long-lasting finish. One crucial step in the process is applying primer.
Before applying primer, it's important to prepare the surface of the fender flares. Start by cleaning the outer surface with a high-quality degreaser, ensuring you never use lacquer thinner or reducer as it will repel the paint. Once the surface is clean, use 200-grit sandpaper to sand down the flares, removing any imperfections and creating a smooth base for the primer to adhere to. After sanding, wipe the flares with a tack cloth to remove any dust.
Now, you're ready to apply the primer. Choose a primer specifically designed for automotive use, such as an enamel or polyurethane primer. These primers are formulated to adhere well to plastic surfaces and provide a durable base for your paint. Lay the flares on a piece of plastic or newspaper to protect your work area from overspray. Hold the primer can 1-2 inches away from the surface of the flares and begin spraying in long, sweeping motions. Try to cover as much of the flare as possible in one sweep to ensure an even coat. Continue spraying until you've applied a full coat to the entire surface of the flares.
If your fender flares have been detached from the vehicle, don't forget to spray a coat of primer inside the interior of the flares as well. This will ensure complete coverage and a consistent finish. Allow the primer to dry thoroughly according to the manufacturer's instructions before moving on to the next step, which is painting.
It's important to work in a well-ventilated area when applying primer and wear a respirator to protect yourself from inhaling any fumes. Once the primer is dry, lightly sand the surface again with a very fine-grit sandpaper or a Scotch-Brite pad to create an even smoother base for your paint. Remove any dust with a tack cloth, and you'll be ready to start applying your chosen paint color.
