Black plastic trim on cars can fade over time due to exposure to UV rays, road salt, dirt, and grime. This can cause the trim to lose its original deep black colour and turn dull and grey. While DIY methods such as using a heat gun, olive oil, or WD-40 can provide temporary improvements, they may not offer long-lasting results and could potentially damage the trim if not applied correctly. To achieve a permanent restoration, it is recommended to use specialised products designed for automotive plastics, such as That Black Stuff or products from Chemical Guys, which can restore the trim's deep black finish and protect it from further degradation.

What You'll Learn
Cleaning and preparing the surface
First, spray down the plastic trim with a dedicated cleaner, such as Nonsense, to loosen and remove dirt, grease, or wax. For textured surfaces, use an exterior detailing brush to scrub the surface in circular, back-and-forth, and up-and-down motions to get into all the nooks and crannies. If using a brush, be sure to follow up by wiping the surface with a clean microfiber towel to remove any remaining residue.
Alternatively, a gentle but effective cleaner can be used to wipe down the surface, ensuring that any dirt, grease, or wax is removed. It is important to avoid over-applying restoration products as this can lead to a sticky finish that attracts dust and dirt. If this occurs, gently remove the excess product with a microfiber cloth until the surface feels smooth.
Once the surface is clean, it is important to ensure it is completely dry. You can use a ProBlow to speed up the drying process and ensure the surface is 100% dry. A thorough cleaning and drying process will help prepare the surface for the next steps in the restoration process.
By properly cleaning and preparing the surface, you can improve the effectiveness of the restoration products and help achieve a more even and long-lasting finish. Remember to always follow the manufacturer's instructions for any products used and take the necessary safety precautions when working on your vehicle.

Using a heat gun
When using a heat gun, it is crucial to set it to a low or medium setting to avoid damaging the plastic. Move the heat gun slowly in sweeping motions, maintaining an even heat distribution. This process should be done carefully, as the high heat from the gun can cause the plastic to melt, warp, or become brittle, ruining its appearance and structural integrity. It is also important to ensure that the plastic trim is clean before starting the process, as dirt and grime can contribute to blotchy results.
The heat gun works by heating the plastic to its glass-transition temperature, causing the crystal structure of the molecules to break down and allowing them to move around again. This process releases the natural oils from the plastic, restoring its colour and shine. However, these oils will eventually deplete, causing the trim to fade again.
To maintain the results, it is recommended to apply a UV protectant or plastic sealant after using the heat gun. This will help prevent sun damage and extend the lifespan of the trim. It is also important to shield the car from direct sunlight and avoid harsh chemicals that can accelerate fading.
While the heat gun method can be effective in restoring the appearance of black plastic trim, it is not a long-term solution. For a more permanent fix, it may be advisable to consider alternative methods such as dedicated plastic restorers or professional techniques. These methods can provide safer and more effective results without the risks associated with heat guns.

Applying a UV protectant
To restore black plastic trim on a car, you can use a UV protectant or plastic sealant to prevent sun damage. Before applying any of these products, it is important to clean and dry the plastic surface thoroughly to remove any dirt, dust, or debris. You can use soap and warm water or a specialised cleaner to remove dirt, grease, or wax. This initial cleaning step is crucial, as failing to properly clean and prepare the surface can hinder product effectiveness, leading to uneven finishes or poor adhesion.
There are various products available on the market, such as Turtle Wax Ice with UV Protectant, which can be sprayed on, or other products that need to be rubbed into the surface. It is important to follow the specific instructions for the product you are using, as application methods may vary. For example, some products recommend using a clean foam applicator pad, microfiber cloth, or sponge for application.
It is also important to note that while UV protectants can help maintain the appearance of your car's black plastic trim, they may not provide a permanent solution. Regular maintenance and reapplication of the UV protectant are necessary to ensure the trim remains protected.
Additionally, to further protect your car's black plastic trim, it is recommended to park your car in a garage or shaded area to avoid prolonged exposure to direct sunlight.

Using a professional service
While there are many DIY methods to renew the black plastic on your car, a professional service is always recommended to prevent future damage. Plastic trim is made from polymer compounds that contain essential oils. Over time, exposure to UV rays, harsh weather, and road debris can deplete these oils, causing the surface to dry out and lose its deep black finish.
Professional car detailers have the expertise and equipment to effectively restore black plastic trim. They may use specialized products, such as high-quality trim restorers, to provide long-lasting results. These products can nourish and re-intensify the colour of plastic, leaving a natural gloss finish.
Additionally, professional services can offer maintenance tips and protective treatments to maintain the restored trim's aesthetic and functional lifespan. They may recommend regular cleaning with gentle, effective products to remove dirt, grease, or wax. Proper maintenance ensures your vehicle maintains its sharp appearance for years.
If your vehicle has damage beyond DIY repair, consider contacting a professional service like BumperTech, which specializes in car scratch repairs, scuffs, touch-ups, and minor dent repairs. They can assess the extent of the damage and provide suitable solutions to restore your car's plastic trim.
By choosing a professional service, you can avoid the potential long-term effects of DIY methods and ensure your car's plastic trim is properly restored and protected.

Once you have applied the specialised restoration product, regular cleaning and maintenance are essential to maintaining the results and extending the lifespan of the restored trim. This includes shielding your car from direct sunlight, using a car cover, or parking in a shaded area to prevent sun damage.
