Over time, black plastic trim on cars will fade, oxidize, and lose their original appearance due to exposure to the sun, inclement weather, and normal wear and tear. To restore black plastic trim, it is recommended to use a plastic restorer, such as Solution Finish Black Trim Restorer, which can restore the factory original colour. Other products such as Mothers Back to Black, Aerospace 303, and CeraKote can also be used to shine and restore colour to faded plastic. It is important to note that some methods, such as using a heat gun, are not recommended as they can cause further deterioration and make the plastic brittle.

Using a plastic restorer
If you are going to use a heat gun, cover any nearby non-plastic surfaces with a tarp to avoid discolouration. Wash the plastic with soap and warm water and dry it with a towel before applying the heat gun.
There are other, more effective plastic restorers on the market, such as Solution Finish Trim Restorer, which can be applied with a microfiber or foam applicator. Wipe off any excess product with a clean towel and allow the plastic to dry for 6 hours. A second application can be applied after 8 months or more and can last even longer.
Other products include Mothers Back to Black, Aerospace 303, CeraKote, and Armor All, which has a product specifically for plastic and vinyl repair.

Cleaning and protecting plastic trim
To clean and protect plastic trim on a car, it's important to use the right products and techniques to maintain your vehicle's appearance and extend the life of the trim. Here are some detailed steps to help you achieve that:
Cleaning the Plastic Trim
Start by using a plastic cleaner or a dedicated trim cleaner to remove any dirt, grime, and old dressings from the plastic surface. You can use a product like Chemical Guys Nonsense All Purpose Cleaner or Trim Clean Wax and Oil Remover to ensure a thorough cleaning. Apply the cleaner to a microfiber towel or applicator pad and work it into the trim using straight, linear motions to avoid swirl marks. Ensure you clean each section thoroughly before moving on to the next step.
Restoring and Protecting the Trim
Once the trim is clean and dry, it's time to restore its luster and provide essential protection. There are several products available for this purpose, such as Chemical Guys VRP Vinyl, Rubber, Plastic Shine and Protectant, Armor All's plastic and vinyl repair product, or Solution Finish Trim Restorer. These products not only enhance the appearance of the trim but also protect against heat damage, UV rays, and environmental elements. Shake the bottle of your chosen product to ensure the formula is evenly mixed, then apply a small amount to a microfiber applicator pad or sponge. Spread the product evenly over the trim, ensuring complete coverage.
Post-Application Care
After applying the restorative product, allow it to dry thoroughly before considering a second coat. For some products, like Solution Finish Trim Restorer, a single application can provide results for up to 8 months or more. However, a second application after the first coat has dried can further enhance and extend the results. Remember to wear gloves and eye protection, as some of these products can stain skin and clothing. Additionally, ensure proper ventilation during the application process.

Using a heat gun
To use a heat gun effectively and safely, follow these steps:
- Prepare the Work Area: Cover any nearby non-plastic surfaces or objects with a tarp to protect them from the heat gun's effects. This method should only be used on plastic car trims and bumpers, and not on plastic attached to flammable materials.
- Clean and Dry the Plastic: Wash the plastic surface with soap and warm water to remove any dirt, grime, or stains. Dry it thoroughly with a towel before proceeding. This step is crucial as using a heat gun on a dirty surface can burn in any dirt or stains, affecting the final result.
- Set Up the Heat Gun: Adjust the heat gun to a low or medium setting. Higher temperatures may warp or discolour the plastic.
- Apply Heat: Hold the heat gun about 3 inches away from the plastic surface and move it in slow, sweeping motions. Ensure even heat distribution across the entire area. Continue until you notice the trim darkening, indicating that the natural oils have risen to the surface.
- Optional - Apply a Protectant: Once the trim has cooled, you may apply a UV protectant or plastic sealant to help maintain the results and prevent sun damage. This step is especially important if your car is frequently exposed to direct sunlight, as it will prolong the effects of the heat treatment.
- Repeat as Needed: The heat gun method is a temporary solution, as the colour will eventually fade, and the plastic will become more brittle with repeated treatments. However, you can repeat the process as needed until the plastic's natural oils are depleted.
While the heat gun method is a quick and budget-friendly fix, it is important to note that it is not a permanent solution. The colour will eventually fade, and you will need to reapply the heat treatment. Additionally, the plastic may become more brittle over time, increasing the chances of cracking or breaking.

Applying a UV protectant
To prevent sun damage and maintain the appearance of your car's black plastic trim, you can apply a UV protectant or plastic sealant. It is important to note that while UV protectants help maintain the appearance of your car's black plastic trim, they may not provide a permanent solution.
Before applying any UV protectant products, it is important to clean and dry the plastic surface. You can use soap and warm water to remove any dirt, dust, or debris. For best results, apply the product to a clean, cool surface in the shade. Ensure adequate ventilation during the application process.
There are a variety of UV protectant products available on the market, and the application method may vary depending on the product. Some products can be sprayed on, while others may need to be rubbed into the surface. Here are some specific products and their application methods:
- Turtle Wax Ice with UV Protectant: This product can be sprayed on and then wiped off after letting it soak.
- Solution Finish Over The Top Plastic Sealer: This product can be applied using a microfiber applicator or foam applicator. Allow it to dry for 20 to 30 minutes, and if needed, additional coats can be applied 30 minutes apart. It is recommended to not apply more than 3 coats. After application, do not wash the treated area for at least 12 hours.
- 303 Aerospace Protectant: This product can be applied using a microfiber sponge applicator.
- Gyeon Preserve: This product can be used a few times a year to treat the trim.
Additionally, some household items can be used as a UV protectant, such as olive oil or avocado oil. Before applying, wash the plastic trim thoroughly to remove any dirt and grime. Once the plastic is clean, dry it off with a towel. Pour a small amount of oil onto a cloth or towel and rub it into the plastic using circular motions. Ensure that you use a light coating to avoid making the surface greasy. Finally, use a dry cloth to buff the surface and remove any excess oil.

Using a plastic trim restorer
There are several products available for restoring black plastic trim, such as Solution Finish Trim Restorer, Mothers Back to Black, Aerospace 303, CeraKote, and Armor All. These products typically require cleaning the plastic trim with isopropyl alcohol or soap and water, applying the restorer with a microfiber applicator or foam applicator, and allowing it to dry for several hours. Some products, like Solution Finish, can be sealed with a UV protectant to enhance and extend the treatment's life.
It is important to wear protective gear, such as gloves and eye protection, and to work in a well-ventilated area when using these products. Additionally, reading the product labels thoroughly and following the instructions is crucial for safe and effective use.
While some products may claim to offer a permanent solution, it is important to note that regular maintenance and re-application are often necessary to maintain the desired results.
