What You'll Learn
Using a plastic restorer
Before applying a plastic restorer, it is important to clean the trim thoroughly to remove any dirt, grime, dust, and surface contaminants. You can use a car wash shampoo and a microfiber car wash mitt to clean the trim. It is recommended to use a separate microfiber towel for restoring plastic trim to avoid any damage to the plastic parts.
Once the trim is clean, you can apply the plastic restorer. You can use products such as Turtle Wax Black in a Flash Trim & Tyre Dressing, which contains conditioning agents to reverse ageing and keep the trim soft and flexible. It is recommended to use a microfiber applicator or foam applicator to apply the product evenly over the trim. Massage the product into the trim until the desired level of restoration is achieved.
After applying the restorer, allow the product to dry for several minutes. Some products may require a longer drying time, such as six hours. You can then wipe off any excess product with a clean cloth or towel.
For added protection, you can use a plastic sealant or sealer, such as Solution Finish Over The Top Plastic Sealer, which protects the trim from UV rays and prevents fading and deterioration. This can be applied as a standalone treatment or as a topper over the plastic restorer.
It is important to note that some plastic restorers may not provide long-lasting results, and reapplication may be necessary. Additionally, some methods, such as using a blow torch or heat gun, may damage the plastic further.

Cleaning with isopropyl alcohol
To restore auto plastic trim, you can use isopropyl alcohol to clean the plastic trim before applying a plastic restorer.
First, ensure that the plastic is clean and dry. Then, apply a small amount of isopropyl alcohol to a microfiber sponge or applicator pad. Spread a thin coat of the alcohol over the area in an even motion, covering the area completely. Allow the solution to penetrate for 3-4 minutes. Use a clean microfiber towel to buff off any excess, and wipe off any glass or paint.
Isopropyl alcohol can be used to remove any cleaners, oils, or silicones from the plastic before applying a plastic restorer. It is important to note that isopropyl alcohol can also remove factory-applied protective coatings, so it should be used sparingly and only when necessary.
After cleaning with isopropyl alcohol, you can apply a plastic restorer to restore the trim. There are various products available, such as Solution Finish Trim Restorer, which can be applied with a microfiber applicator or foam applicator. After application, wipe off any excess product with a clean towel and allow the plastic to dry for 6 hours.
In addition to restoring the trim, you can also apply a UV protectant or plastic sealant to prevent sun damage and fading. This can be done using products such as Solution Finish Over The Top Plastic Sealer, which can be used as a standalone treatment or as a topper on plastics that have been restored with a restorer.

Sealing with a UV protectant
One option is to use a dedicated UV protectant product, such as Turtle Wax Ice, Plexus, Aero 303, or Gyeon Preserve. These products can be applied directly to the trim to provide protection against UV rays. Some users have reported that 303 works well for interior trim but is less effective for exterior trim, as it is water-based and washes off quickly. In contrast, Turtle Wax Ice is a clear spray-on wax that can be used on exterior trim and has been reported to work well in high-temperature environments.
Another option is to use a trim sealant or sealer, such as Solution Finish Over The Top Plastic Sealer, which can be used as a standalone treatment on new or well-maintained plastic trim, or in combination with a trim restorer. This type of product fills the void in the market for a long-lasting UV protectant that does not need to be reapplied after every car wash.
Additionally, some all-in-one products, such as CAR GUYS Plastic Restorer, claim to both restore and protect plastic trim. This product is designed to renew, seal, and protect any interior or exterior surface and is reported to last for several months.
It is worth noting that some high-end car manufacturers recommend using talcum powder on door and hood seals to provide lubrication and extend the life of the seals. However, these seals typically require less frequent treatment compared to exposed rubber seals, which receive heavy UV radiation from the sun.
While chemical protectants can help, the best UV protection for a car is to store it in a garage, especially in areas with high UV intensity.

Sanding and painting
Preparation
Before you start sanding and painting, it is essential to clean the plastic trim thoroughly. Use a degreaser or soap and water to remove any dirt, grime, or old paint. Ensure the surface is completely dry before proceeding to the next step.
Sanding
Use fine-grit sandpaper to sand the trim, working in circular motions to remove any imperfections. Be sure to sand in the direction of the trim's grain to avoid creating scratches. Take your time during this process, as a good sanding job will result in a better final product.
Priming
Once the plastic trim is sanded, it's time to apply a coat of primer. Choose a high-quality primer specifically designed for plastic trim, and follow the manufacturer's instructions for application and drying times. Make sure to cover the entire surface with the primer, creating a smooth and even base for the paint.
Painting
Select a high-quality paint designed for plastic trim. Look for paints that are UV-resistant, flexible, and have good adhesion properties. Use a paintbrush or roller to apply the paint, working in thin coats to avoid pooling or drips. Apply the paint in light mist coats, adding additional coats as necessary.
Clear Coat
After painting, apply a clear coat to protect the paint and give it a glossy finish. This step is important to ensure the paint job lasts longer and maintains its shine.
Additional Tips
- Always work in a well-ventilated area and wear protective gear, including gloves, safety glasses, and a mask, to prevent exposure to chemicals and paint fumes.
- Mask off surrounding areas with tape to protect them from paint and primer.
- For best results, ensure the plastic trim is cool and clean before painting.
- Some products, like ColorBond Clear Adhesion Promoter, can be applied before painting to enhance adhesion and durability.
By following these steps and taking your time, you can achieve a professional-looking finish that will enhance the appearance of your car.

Applying oil
To restore auto plastic trim, you can use olive oil, boiled linseed oil, or peanut butter. These methods are temporary, as the oil will wash off with repeated washings or weather exposure.
First, clean the plastic trim with soapy water to remove surface grime, dust, and dirt. Rinse well with clean water and wipe dry with a microfiber towel.
Next, apply a small amount of oil to a clean microfiber towel. Rub the oil onto the faded trim in circular motions, ensuring that the oil covers all the faded areas. If the cloth becomes dirty, turn it over, apply more oil, and continue rubbing.
Let the plastic trim absorb the oil by letting it soak for five to ten minutes. Then, grab a separate dry towel and buff the surface lightly using rapid circular motions. Turn the towel over and give it a final buff.
To maintain the restored appearance, reapply oil at least weekly and take preventive measures to protect the trim from sun damage. Park your car in a garage or shaded area, and avoid harsh chemicals and automatic car washes that can strip protective coatings and accelerate fading.
