How to permanently restore faded black plastic trim

Over time the black plastic trim on your vehicle can begin to fade to a washed-out shade of grey. With just a few products you can restore your faded trim and prevent it from ruining the look of your car.  

Most cars have plastic trim somewhere on their body. Places like the wheel arches, the bumper or below the windshield are popular spots for plastic trim. While the paint on your car is protected by a clear coat, these plastic areas are always exposed to UV from the sun. Unfortunately, no matter how often you detail your exterior, the faded black trim can ruin the overall look of your vehicle.

What plastic restorer do you recommend? 

We like PERL Coat by CarPro for its protective properties. It can be used on plastics, rubber, and leather, which can also fade or become brittle and crack. PERL Coat lasts for up to three months on interior surfaces. While it’s also suitable for your exterior, its longevity will vary depending on exposure to the rain. For superior exterior protection, we recommend the Pro DLux Plastic, Rubber and Alloy Protection.

How do I restore my black plastic trim?

1. Start by parking your vehicle in the shade and working somewhere with plenty of ventilation. Avoid working in a garage or small space. It is best to work outside on a cool day.
2. Give your black plastic trim a clean with isopropyl alcohol and a clean towel. This will help remove any dirt, grime or wax residue from the surface of the trim. If you can, remove the piece of trim before applying the solution.
3. Using a microfiber applicator or foam applicator apply a restoring solution to the black plastic trim. If you can’t remove the trim, use painters' tape to protect your vehicle’s paint job.
   
   

How can I tell if my trim needs to be treated?

The trim on most cars is dark black when it leaves the factory. Over time, your trim may fade to a lighter shade of black, or even grey. Additionally, you might notice white stripes appearing in the grey trim. The stripes correspond with stress bands in the plastic. As the plastic expands and contracts with temperature changes, the weakest portions of the plastic break down first, forming these bands.
