What You'll Learn
Clean the plastic trim with isopropyl alcohol
To darken black plastic in your car, you can use a plastic restorer to restore black plastic trim. Before applying a plastic restorer, it is important to clean the plastic trim with isopropyl alcohol to ensure there is no residue, only bare plastic. Isopropyl alcohol is good at removing oils, grease, and waxes. It is recommended to dilute the isopropyl alcohol, especially when using it on plastic, as it comes in many versions and makeups. You can test how the isopropyl alcohol works on a small area that is not easily visible.
After cleaning the plastic trim with isopropyl alcohol, you can use a microfiber applicator or foam applicator to apply the plastic restorer. Make sure to wipe off any excess product with a clean towel. Allow the plastic to dry for at least 6 hours before determining if a second application is needed.
It is important to note that some sources recommend using a heat gun or olive oil to restore the shine to black plastic. However, using a heat gun on dirty plastic can burn in any dirt or stains, so it is crucial to clean and dry the plastic before applying heat. Additionally, the use of a heat gun is not a long-lasting solution, as the plastic may eventually fade, and after several treatments, there may not be enough natural oils to restore.

Apply a UV protectant to prevent sun damage
If you want to prevent sun damage to your car's black plastic, applying a UV protectant is a good option. UV rays can cause plastic to crack and fade, so using a protectant will help to maintain the appearance of your car.
There are several products available that can protect your car's plastic from UV damage. One option is to use a plastic restorer, such as Solution Finish Trim Restorer, which can restore the black colour of faded plastic and protect it from further damage. This product can be applied using a microfiber or foam applicator and should be left to dry for at least 6 hours. Another option is to use a UV-resistant trim shine, which can gently restore faded black plastic without the need for heavy-duty chemicals.
If you're looking for a more natural solution, olive oil can be used to restore the shine to faded plastic. Simply rub the oil into the plastic and inspect the results. If there are still patches of discolouration, you can try the process again, targeting the affected areas.
For a longer-lasting solution, you can use a heat gun to bring out the natural oils in the plastic and restore its lustre. However, this method may not be effective after multiple treatments, as the plastic will eventually run out of natural oils. Additionally, it is important to note that heat guns can warp or discolour the surfaces of non-plastic items, so nearby objects should be covered with a tarp before using the heat gun.
Another option for UV protection is to use a ceramic coating, such as Cerakote or CQuartz. These coatings can be applied over a solution like Solution Finish to protect the finish and prevent fading. However, it is important to note that some products, such as polishes, may interfere with the effectiveness of the coating.
Finally, there are also spray-on protectants available, such as 303 Automotive Protectant, which can be used to shield the interior and exterior of your car from sun damage. This product is safe to use on various materials, including plastic, and can be easily applied by spraying and wiping the surface with a microfiber towel.

Use a heat gun to restore the plastic's natural oils
Using a heat gun is a great way to restore the natural oils in black plastic trim and bumpers in your car. This method is a temporary solution, as the plastic will eventually fade with use and deplete its natural oils. The heat from the sun attracts moisture from the air, and as the plastic cools, the moisture gets trapped in the closed cells, causing a cloudy grey discolouration.
Heat guns open up the cells and allow the moisture to escape, and also draw out the natural oils in the plastic, restoring its colour. The heat gun should be set to a low or medium setting to avoid warping the plastic, and moved in slow, sweeping motions to ensure even heat distribution. Cover any nearby non-plastic objects with a flame-resistant tarp to avoid discolouration, and ensure the plastic is clean and dry before applying heat.
The heat gun method is not a permanent fix, as the natural oils will eventually deplete again, and the plastic will need to be re-treated. The treatment can last from as little as a few weeks to a year, depending on the environment and exposure to sunlight.
If the heat gun method no longer works, you can try adding olive oil to the plastic's surface to restore its shine.

Apply a black plastic trim moisturiser
If you want to darken the black plastic trim on your car, one option is to use a black plastic trim moisturiser. These products restore car trims by adding moisture to their surface. You can buy car trim moisturisers at most automotive stores.
Before applying a moisturiser, it's important to clean the trim thoroughly to remove any dirt, grease, and previous products. You can use a trim cleaner or degreaser for this step. Once the trim is clean and dry, you can apply the moisturiser. Be sure to follow the specific instructions on the product you choose, as different products may have different requirements.
One popular product is the YumCars Dress V2 Rubber & Trim Moisturiser, which is designed to hydrate and protect rubber and plastic trims, preventing them from cracking and fading over time. It provides a subtle, satin finish and is excellent for maintaining the natural look of your trim without leaving a glossy shine.
Another option is to use a heat gun on the faded area, which can bring out the natural oils in the black plastic and restore its lustre. However, this is not a long-lasting solution, as the plastic will eventually fade again, and after several treatments, it will no longer have enough natural oils to restore. Additionally, using a heat gun on dirty plastic can burn in any dirt or stains, so it's important to clean and dry the plastic before applying heat.
For a more permanent solution, you can use a plastic restorer or a trim restorer. These products can penetrate deeply, replenishing the plastic's natural oils and providing a protective layer to extend longevity. However, some restorers may not be effective on severely faded trim, and they can be time-consuming and costly if the trim needs to be replaced.

Use a plastic restorer to restore black plastic trim
Using a plastic restorer is a cost-effective way to improve the appearance of your car's black plastic trim. It is a simple process, but it is not a long-term solution. The plastic will eventually turn grey and dull again, as the restorer does not repair the damage caused by UV exposure.
To use a plastic restorer, start by cleaning the plastic trim with isopropyl alcohol to ensure there is no residue, only bare plastic. Then, use a microfiber applicator or foam applicator to apply the restorer onto the plastic. Spread a thin coat over the area in an even motion, covering the area completely. Allow the solution to penetrate for 3-4 minutes, then use a clean microfiber towel to buff off the excess and wipe off any product that gets on glass or painted surfaces. Finally, allow the plastic to dry for 6 hours.
For best results, apply the restorer to a clean, cool surface in the shade. Avoid getting the product on painted or glass surfaces, as it may stain. After the first application, your trim will stay black and looking new for approximately 8 months or more. A second application can last even longer, as some products work to fix the damaged plastic, not just dress it.
There are many different products available for restoring black plastic trim. Some popular options include Solution Finish, Over The Top, CeraKote, and Mothers Back to Black. You can purchase these products from auto parts shops or online stores, and they typically cost between $15 and $40 per bottle.
It is important to note that while some sources recommend using a heat gun to restore black plastic trim, others caution that this method can cause the plastic to warp and accelerate its deterioration. If you choose to use a heat gun, be sure to start with a clean or freshly-washed surface and heat one area at a time to prevent damage. You can also treat the surface with olive oil, WD-40, or a trim restoration product after heating to make the surface darker and protect it from sun and rain.
