Faded plastic door panels can be caused by UV damage from sunlight. To restore the colour, you can use products such as bike polish, Turtle Wax Trim Restorer, Johnson Paste Wax, or Surf City Garage's Black Maxx. Some people also recommend using a heat gun, or cleaning the door panels with a damp cloth and armour all.

What You'll Learn
Using a heat gun
Restoring plastic door panels using a heat gun is an effective and affordable method. It is a simple process that can be done at home and can bring back the vibrant colour and shine of the plastic.
To begin, ensure that the door panel is clean. Wash it with soap and water using a scrub brush or a power washer on a low setting. This step is important as years of cleaning products can result in blotchy outcomes. Once the door panel is clean and dry, you can start using the heat gun.
It is recommended to use a good quality heat gun, such as a Porter-Cable gun, for effective results. When using the heat gun, work slowly and methodically, moving in an even pattern without jumping around. Hold the heat gun four to six inches away from the surface of the door panel. Be cautious not to apply too much heat, as it can melt the plastic and cause discolouration. Adjust the heat setting accordingly, and if the plastic has a textured surface, avoid using a very high heat setting.
The heat from the gun will cause the plastic to soften and reform, smoothing out any cracks or scratches and restoring the colour. Depending on the severity of the damage, you may need to apply heat for a longer duration or adjust the temperature. It is important to be patient and careful during this process to avoid any unwanted changes in the plastic's properties.
After treating the door panel with the heat gun, allow it to cool down. You may need to repeat the process a few times to achieve the desired results. With the right technique and equipment, you can restore the plastic door panel to its original condition.

Scrubbing
First, it is important to choose the right cleaning agent. A mild cleaner can be used to scrub the plastic gently. Avoid using harsh chemicals or abrasive cleaning agents, as these may damage the plastic. It is also important to note that some products, like armour all, are not meant to be used as cleaners but rather as a protective coating after scrubbing and restoration.
Next, dampen a cloth with water and apply a small amount of the chosen cleaner. Gently scrub the plastic door panel, focusing on areas with fading or discolouration. Be careful not to scrub too aggressively, as this may scratch the plastic. Work in small sections and rinse the cloth frequently to avoid spreading dirt around.
If the door panel has extensive fading or discolouration, a heat gun can be used before scrubbing. Apply heat to the affected area and then scrub as usual. The heat can help soften the plastic and make it more receptive to the cleaning process. However, use caution when handling a heat gun to avoid accidental burns or melting the plastic.
After scrubbing, it is important to rinse the door panel with a clean, damp cloth to remove any residual cleaner. Ensure that the cloth is only slightly damp, as too much water can negatively affect the electrical components of the door. Dry the panel thoroughly with a soft, absorbent cloth.
Once the door panel is clean and dry, it is important to apply a protectant or restoration product to help maintain its appearance and prevent future fading. There are various products available, such as Torque Detail's Plastic Restore, 303 Aerospace Protectant Spray, Turtle Wax Trim Restorer, and Johnson Paste Wax. These products can enhance the colour and shine of the plastic, offering a consistent and improved appearance.

Using a protectant spray
Choosing the Right Protectant Spray
Select a protectant spray that is specifically designed for plastic surfaces. Look for options like Silk Shine Vinyl, Rubber & Plastic Protectant, Meguiar's Gold Class Dash & Trim Foam Protectant, Torque Detail's Plastic Restore, or 303 Aerospace Protectant Spray. These products are formulated to restore and protect plastic surfaces without leaving a greasy residue.
Preparing the Surface
Before applying the protectant spray, ensure that the plastic door panels are thoroughly cleaned and dried. Use a soft microfiber cloth or towel and a pH-balanced, automotive-safe cleaner to remove any dirt, grime, or residue. Work from the top down to prevent dirt from spreading to already cleaned areas. For stubborn spots, use an all-purpose cleaner, but avoid household cleaners with harsh chemicals that can damage plastic.
Applying the Protectant Spray
Once the surface is clean and dry, it's time to apply the protectant spray. Follow the instructions on the product you've chosen, as application methods may vary. Typically, you'll spray the protectant directly onto a clean microfiber cloth or towel and then gently wipe it onto the plastic door panels in circular motions. Ensure you cover the entire surface evenly.
Drying and Final Inspection
After applying the protectant spray, allow it to dry completely. Use a separate, dry microfiber cloth to remove any excess moisture and prevent streaks or residue. Once the panels are dry, inspect them closely to ensure there are no areas that require additional attention. If needed, apply a second coat of the protectant spray for added protection.
Maintenance
To maintain the restored appearance of your plastic door panels, reapply the protectant spray periodically. Follow the manufacturer's recommendations for reapplication intervals. Regular maintenance will help keep your plastic door panels looking their best and protect them from the elements.

Applying bike polish
To restore plastic door panels, you can use a product like Torque Detail's Plastic Restore or 303 Aerospace Protectant Spray. You can also apply bike polish to the plastic door panels.
Firstly, clean the plastic door panels with soapy water and rinse them. You can also use a pressure washer, but avoid spraying the chain as it can trap dirt and water. If there is built-on dirt, you may need to wash the plastic a few times. Then, wipe the panels dry with a soft cloth.
Next, use a utility blade to scrape away any built-on dirt or scratches. Always be cautious when handling sharp blades. If there are still scratches remaining, use moistened 400-grit sandpaper to sand them out. You can also use a finer sandpaper, such as 800 or 1000-grit, for a smoother finish. After sanding, wipe the plastic with a soft cloth to remove any grit.
Finally, attach a 4-inch buffing wheel to a power drill and buff the plastic to a high polish. Tilt the buffing wheel so that only the edge touches the plastic, and press gently as you move it back and forth. Be careful not to hold the buffing wheel in one spot for too long, as it can heat up and melt the plastic. You can also add a polishing compound to the buffing wheel for extra shine.

Using adhesion promoter
Adhesion promoters are a great way to restore plastic door panels. They help soften the plastic, providing a chemical bond and a better mechanical bond for the paint to stick to the plastic.
Before applying an adhesion promoter, it is important to clean the door panels thoroughly. Use lint-free shop towels to clean the panels. You can use a wax and grease remover for this step, wiping it on and then off with a dry cloth. You can also use window cleaner or soapy water, ensuring the panels are clean and free of any residue. If there are any loose materials on the panel, sand it down with 320-grit sandpaper to smoothen the surface.
Once the panel is clean and prepared, you can apply the adhesion promoter. It is recommended to use a spray adhesion promoter, applying two medium coats with a 15-minute dry time between coats. This will ensure the adhesion promoter is evenly distributed and provides a strong bond.
After applying the adhesion promoter, you can proceed with the next steps in the restoration process, such as applying a top coat of paint within an hour, as recommended by some sources. It is important to follow the specific instructions of the adhesion promoter product you are using for the best results.
Using an adhesion promoter is an effective way to ensure a strong bond between the paint and the plastic door panel, helping to achieve a durable and long-lasting restoration.
