Black plastic trim on cars is prone to fading and discolouration over time. This is due to exposure to sunlight, harsh weather, and road debris. The plastic trim loses its original colour, fading to a dull grey or whitish colour. This makes the car look older than it is. There are several methods to restore black plastic trim, ranging from DIY fixes to professional solutions. DIY methods include using olive oil, peanut butter, or a heat gun to temporarily restore the black colour. Professional solutions involve using high-quality trim restorers and sealants to provide a more permanent solution. These products protect the trim from UV rays and external contaminants, maintaining the trim's appearance. Proper maintenance and regular use of protectant products can also help extend the time between restorations.

What You'll Learn
Using a heat gun
There are various theories about how this process works. One theory suggests that the heat brings the oils in the plastic to the surface, making the trim look darker and shinier. Another theory proposes that the heat melts the rough fibrous surface, smoothing it out and restoring its original colour. Some also believe that the heat causes the pigment in the plastic to rise to the surface, covering any faded areas.
While the heat gun method can provide good results, it is important to note that it is not a permanent solution. The trim will eventually fade again as the oils deplete, and the plastic may become more brittle with repeated applications. Additionally, it may not always produce consistent results, with some users reporting spotty or splotchy outcomes.
To prolong the results of the heat gun treatment, it is recommended to apply a UV protectant to the trim after the process. This will help prevent the trim from fading due to sunlight exposure. It is also advised to maintain proper maintenance and care of the trim to keep it in good condition.
Overall, using a heat gun can be an effective way to quickly restore black plastic trim. However, for a more permanent solution, it may be better to use a high-quality trim restorer product or seek professional-grade solutions.

Applying olive oil
To restore black plastic trim, you can use olive oil to condition it. This is a temporary solution, as olive oil washes off easily with rain or car washes. However, it can be an effective way to improve the appearance of faded trim.
Firstly, clean the plastic trim thoroughly to remove any dirt, grime, or residue. You can use soap and water, or isopropyl alcohol to ensure the surface is clean. Dry the plastic trim with a towel.
Next, apply a small amount of olive oil to a clean microfiber towel or a washcloth. You only need a coin-sized amount of olive oil, as a little goes a long way. Rub the olive oil onto the plastic trim in circular motions, covering the area evenly.
After rubbing the oil into the plastic for a few minutes, use a dry cloth to buff the trim. This will remove any leftover oil and help to avoid streaking.
If the olive oil does not restore the black plastic trim, you can try other methods such as using a heat gun or painting the trim. It is recommended to use a primer before painting to help the paint adhere to the surface. Additionally, you can apply a UV protectant or plastic sealant to prevent sun damage and fading in the future.

Using a plastic restorer
First, clean the plastic trim thoroughly to remove any dirt, grime, or residue. You can use soap and warm water for this step, ensuring the trim is dry before moving on. Next, prepare the plastic restorer product of your choice according to its instructions. Most products will involve applying a small amount of the product to a microfiber cloth or applicator pad. Spread the product evenly over the trim, covering the area completely. Some products may require you to let the solution penetrate for a few minutes.
After application, use a clean microfiber towel to buff off any excess product. Be sure to wipe off any excess from nearby glass or painted surfaces as well. Allow the plastic trim to dry completely. This may take around 6 hours. For best results, apply the restorer in a well-ventilated area, to a clean and cool surface, and always wear gloves and eye protection.
It is important to note that while plastic restorers can provide effective results, they may not be permanent solutions. Some products may only last a few weeks, while others can keep the trim looking new for up to a year with proper maintenance. Repeated applications of certain products may also be necessary to maintain the desired appearance. Additionally, some plastic restorers may not repair the underlying damage, and the trim may eventually return to its faded state.
It is always a good idea to research the specific product you intend to use and follow its instructions for the best results.

Applying a plastic primer
To apply a plastic primer, you must first prepare the plastic surface. Clean the plastic trim with a product such as IPA 70-90% (Isopropyl Alcohol) to remove any cleaners, oils or silicones. You can also use thinners to wipe the surface clean. Once the plastic is dry, sand down the surface with sandpaper to ensure it is smooth and remove the shiny surface. This will help the primer and paint adhere to the plastic.
Before applying the primer, ensure you are wearing a mask to protect yourself from the chemicals. Shake the can of primer as per the instructions, and hold the can around 6-7 inches away from the plastic surface. Apply a couple of light coats of primer, leaving 10 minutes between each coat to dry. Two to four coats should be enough, as long as they are nice and even. Leave the primer to dry properly overnight.
After priming, you can apply a guide coat, which is a very light misty coat of black paint over the primer. This will help when flattening the surface. You can then apply your chosen paint colour, using three to four coats, and waiting 15 minutes between each coat to allow each layer to dry.
For interior plastics, use a top-quality acrylic spray paint, and for outdoor plastics, use a spray paint designed for plastics.

Using a UV protectant
The sun's UV rays can be particularly harsh on black plastic trim, causing it to fade and deteriorate over time. To protect your trim from UV damage, you can use a UV protectant or a trim restorer that contains UV-blocking polymers.
One recommended product is the Solution Finish Over The Top Plastic Sealer, which can be used as a standalone treatment on new or well-maintained plastic trim. It protects plastic from harmful UV rays and prevents fading and deterioration. Another option is CeraTrim, a ceramic coating that provides long-lasting protection against UV rays while restoring the trim's appearance.
If you're looking for a more budget-friendly option, you can try household items like olive oil or WD-40, which can temporarily darken and add shine to plastic trim. However, these solutions are not long-lasting and will wash off easily.
When applying a UV protectant or trim restorer, it's important to follow the manufacturer's instructions. In general, it is recommended to apply the product to a clean, cool surface in a well-ventilated area. Use a foam applicator pad or a microfiber sponge to spread the product evenly over the trim, ensuring that it penetrates the pores and texture of the plastic surface. Allow the product to set and dry for a few minutes, then use a clean microfiber towel to wipe away any excess.
Remember, it is much easier to prevent UV damage than to restore faded trim. By regularly maintaining your trim and applying UV protectants, you can keep your black plastic trim looking new for longer.

Frequently asked questions
There are several methods to condition black plastic trim. You can use a high-quality trim restorer, a heat gun, olive oil, or black spray paint.
The best method for conditioning black plastic trim depends on various factors, such as personal preference, budget, and the condition of the trim. High-quality trim restorers provide the most effective and lasting results, but they can be costly. For a quick and budget-friendly fix, olive oil or WD-40 can be used, but these solutions are short-lived.
First, wash and dry the plastic trim. Set the heat gun to a low or medium setting to avoid warping the plastic. Move the heat gun in slow, sweeping motions, ensuring even heat distribution. Once the trim darkens, apply a UV protectant to maintain the results.
