Black plastic trim on cars is prone to fading and discolouration over time, which can make the car look older than it is. There are several ways to restore black plastic trim, including using a plastic restorer, olive oil, a heat gun, or spray paint. To prevent fading and discolouration, it is important to clean and protect the plastic trim regularly, using products such as UV-resistant trim shine, plastic sealant, or a plastic restorer.

What You'll Learn
Using a heat gun
To use a heat gun for reconditioning black plastic gloss, follow these steps:
- Clean and dry the plastic surface thoroughly: Wash the object with soap and water to remove any dirt, debris, or stains. Then, dry it off with a towel before applying heat. This step is crucial as using a heat gun on a dirty surface can burn in any dirt or stains, affecting the final result.
- Cover nearby non-plastic objects: Heat guns generate intense heat, which can warp or discolour nearby non-plastic items. Cover any non-plastic surfaces or objects in the vicinity with a flame-resistant tarp to protect them from the heat.
- Test the heat gun on a small area: Before treating the entire surface, test the heat gun on an inconspicuous area of the plastic. This will allow you to observe the colour change and ensure you are satisfied with the results.
- Apply heat in a concentric pattern: Hold the heat gun several inches away from the surface and turn it on. Move the heat gun in small circles or a concentric pattern around the discoloured plastic. Avoid keeping the heat gun in one place for too long to prevent burning or discolouration.
- Observe the "sweating" and colour change: As you apply heat, you will notice spots appearing on the plastic's surface, indicating that the plastic is sweating. Continue moving the heat gun in a concentric pattern, and you will see the colour gradually deepen to a darker, richer shade of black.
- Adjust the heat as needed: If you notice some areas becoming shiny, this is a sign that the plastic is getting too hot and starting to melt. In this case, stop applying heat and allow the surface to cool down before continuing. It is important to be patient and adjust the heat as necessary to avoid damaging the plastic.
- Inspect the final result: Once you have treated the entire surface, turn off the heat gun and inspect the plastic's new colour. Ensure that you are satisfied with the colour and that it is consistent across the entire surface.
While using a heat gun is a relatively simple and affordable way to restore black plastic gloss, it is important to recognise its limitations. This method may not provide long-lasting results, especially if the treated object is frequently exposed to direct sunlight. Additionally, repeated treatments can deplete the plastic's natural oils, rendering this technique ineffective over time. Therefore, it is recommended to explore alternative solutions, such as applying olive oil or specialised plastic restoration products, for more durable results.

Applying olive oil
Olive oil can be used to restore black plastic to its natural colour, removing any faded or discoloured areas. This method is ideal for car trims and bumpers, which are prone to fading and discolouration over time.
To use olive oil to recondition black plastic, follow these steps:
Firstly, ensure the plastic surface is clean and dry. Wash the plastic with soap and warm water to remove any dirt or debris. Dry the surface with a towel before applying the olive oil to prevent the oil from slipping off.
Next, pour a small amount of olive oil onto a cloth. A coin-sized amount is usually sufficient, and you can always add more later if needed. Massage the olive oil into the plastic using the cloth. Rub the cloth back and forth on the targeted area for several minutes to help the plastic absorb the oil.
To avoid getting olive oil on nearby objects, cover them with a tarp or towel. If there are any non-plastic objects nearby, be sure to cover them, as olive oil can discolor non-plastic surfaces.
After rubbing the olive oil into the plastic, take a dry cloth and buff the plastic in circular motions. Apply heavy pressure to remove any excess oil and grease, and to give the plastic an extra shine.
Finally, inspect the plastic for any residual discolouration. If there are any patches that the olive oil did not restore, try repeating the process, adding more oil and directly targeting the stubborn area.
Note that olive oil may not be a long-lasting solution for restoring black plastic. For severe fading or discolouration, you may need to consider alternative methods such as using a heat gun, black spray paint, or a black plastic trim moisturizer.

Using a plastic restorer
If you wish to proceed with a plastic restorer, there are a few steps to follow. Firstly, ensure the plastic surface is clean and dry. Wash the plastic trim with isopropyl alcohol to remove any residue, leaving only bare plastic. You can also use soap and warm water to clean the surface, especially if the plastic is dirty.
Next, prepare the plastic restorer for application. One recommended product is the Solution Finish Black Plastic Restorer. Shake the bottle well, and apply a small amount to an applicator pad or a microfiber sponge.
Afterward, spread the product evenly over the plastic surface, ensuring complete coverage. Allow the solution to penetrate the plastic for 3-4 minutes. Use a clean microfiber towel to buff off any excess product. Ensure you wipe off any glass or paint to avoid staining.
For best results, apply the plastic restorer to a clean, cool surface in a shaded area. Additionally, ensure adequate ventilation during the application process. It is also recommended to wear gloves and eye protection as the solution can stain clothing and skin.
After the first application, your trim will remain black and look new for approximately eight months or more. A second application can further extend the results. To enhance and prolong the effects of the treatment, you can use a UV protectant product, such as Solution Finish Over The Top Plastic Sealer, which will protect the plastic from harmful UV rays.

Applying a plastic sealant
For best results, it is recommended to apply the sealant to a clean, cool surface in a shaded area. It is also important to wear protective gear, such as gloves and eye protection, as some sealants can stain clothing and skin.
There are various plastic sealants available on the market, such as the Wolfgang Deep Gloss Paint Sealant, Turtle Wax Ice Seal and Shine, and Gtechniq c4 trim restorer. When applying the sealant, it is important to follow the specific instructions provided by the manufacturer. However, a general application process involves shaking the bottle well and applying a small amount to an applicator pad or microfiber sponge. Spread the sealant in an even, thin coat over the entire area, allowing it to penetrate for a few minutes.
After application, use a clean microfiber towel to buff off any excess sealant. It is important to note that different sealants have varying curing times, with some recommending that the treated area not be washed for at least 12 hours after application.
In addition to commercial sealants, some natural alternatives can be used as temporary solutions. For example, olive oil can be applied to a clean surface to restore the black plastic's natural colour and shine. Similarly, a heat gun can be used to bring out the natural oils in black plastic, but this method may not be long-lasting and can eventually lead to the depletion of natural oils.

Spray painting
To recondition black plastic gloss with spray paint, you can follow these steps:
First, you need to prepare the plastic surface by washing and drying it. This will help remove any dirt or residue and ensure that the paint adheres properly. You can use soap and warm water to clean the plastic surface and then dry it off with a towel.
Next, you need to apply a coat of primer. The primer will help the paint stick to the plastic surface and provide a more even finish. Spray a light and thin coat of plastic primer over the surface, holding the nozzle about 12-18 inches away, and follow the recommended drying time on the packaging, which is usually between 30 minutes to an hour. Avoid applying heavy or multiple coats of primer as it can alter the texture of the plastic.
Once the primer is dry, you can start spraying the plastic with black spray paint. Hold the nozzle at a similar distance as before and move the can in smooth, overlapping strokes to ensure even coverage. Apply 3-4 coats of paint, allowing each coat to dry in between applications. Each coat should take around 30-60 minutes to dry, but always refer to the paint's packaging for specific instructions.
After the final coat of paint has dried, you can apply a clear coat or lacquer for added protection and shine. This will help prevent the paint from fading, chipping, or streaking. Again, follow the recommended drying times and application instructions for the clear coat or lacquer.
It is important to note that spray painting plastic requires good ventilation and protective gear, such as gloves and a respirator, to ensure your safety during the process. Additionally, always test the spray paint on a small, inconspicuous area first to ensure that it reacts well with the plastic and primer.
By following these steps, you can effectively recondition black plastic gloss with spray paint, giving it a sleek and shiny new finish.
