Cleaning Wash the trim with soap and warm water, and dry it with a towel before applying any restoration products.
Temporary solutions Using a heat gun can bring out the natural oils in the plastic and restore its luster, but this is not a long-lasting solution and can cause warping and deterioration. Applying olive oil or WD-40 can also restore the shine.
Permanent solutions Use a plastic restorer or trim restoration product, such as Solution Finish Trim Restorer, Torque Detail Plastic Restore, or Lemon Pledge. Apply with a microfiber applicator or foam applicator, and allow to dry for several hours. A UV-resistant sealant can also be used for protection.
Alternative solutions If the trim is severely damaged, it may be necessary to replace it with a new piece. Spray paint can also be used to restore the color, but a primer should be applied first.

Using a heat gun and olive oil

Restoring black plastic auto trim with a heat gun and olive oil is a simple process, but it is not a permanent solution. The heat gun draws out the oils within the plastic, and the olive oil restores shine and offers some protection. Here is a step-by-step guide:

Preparation

Before you begin, ensure you have the right equipment. You will need a heat gun, which you can buy or rent from hardware stores or online. You will also need olive oil, a washcloth or paper towel, and a flame-resistant tarp.

Cleaning

Start by cleaning the plastic trim with soap and warm water to remove any dirt, grime, or debris. This step is important as using a heat gun on a dirty surface can burn contaminants into the plastic. Dry the surface with a towel.

Heat Gun Treatment

Once the plastic is clean and dry, heat up the heat gun. If your plastic trim is attached to non-plastic surfaces, cover those areas with the flame-resistant tarp, as heat guns can warp or discolour non-plastic surfaces. Work on one small area at a time, gently heating up the plastic. Keep the heat gun moving, and do not use a high-powered setting, as this can damage the plastic. As you apply heat, you will see the plastic's colour change to a darker, richer shade as the oils are drawn out.

Olive Oil Treatment

After you have finished applying heat, inspect the colour of the plastic. If it still looks faded, it is time to apply the olive oil. Pour a coin-sized amount of olive oil (extra virgin is best) onto a dry microfiber towel or washcloth. Gently rub the oiled towel onto the plastic using small, circular motions, adding more oil as needed. Allow the plastic to absorb the oil for 5-10 minutes.

Buffing

Finally, grab a separate dry towel and buff the surface lightly using rapid circular motions. Turn the towel over and give it a final buff to remove any excess oil and achieve an even finish.

Aftercare

This treatment will not protect your trim indefinitely. The olive oil will wash off over time, and the plastic's natural oils will eventually deplete again. To maintain the trim's colour and shine, you will need to repeat the treatment regularly, applying olive oil at least weekly. You can also take preventive measures, such as parking in a garage or shaded area, to minimise sun damage.

Applying plastic restorer

To apply plastic restorer, start by cleaning and drying the plastic trim. Wash the trim with soap and water, removing as much dirt as possible, and dry it off with a towel. This will help the plastic restorer absorb into the trim.

Next, apply the plastic restorer. Most products recommend using a microfiber applicator or foam applicator to apply an even coat of the product onto the plastic. Spread a thin coat over the area, covering the area completely. Wipe off any excess product with a clean towel.

Allow the plastic to dry for several hours. The specific drying time may vary depending on the product used, so be sure to follow the instructions on the chosen product.

After the restorer has dried, you may want to consider applying a UV-resistant sealant to protect the plastic from fading and deterioration caused by sun exposure. Products like Solution Finish Over The Top Plastic Sealer can be used as a standalone treatment on new or good-condition plastics, or as a topper on plastics that have been restored.

For best results, reapply the plastic restorer regularly, especially if the trim is constantly exposed to the sun.

Using UV-resistant trim shine

Using a UV-resistant trim shine is an effective way to restore black plastic auto trim. The sun's UV rays are one of the most common reasons for black plastic trim to fade and deteriorate, so using a UV-protectant product can help prevent this.

There are several products available that can provide a UV-resistant trim shine for black plastic auto trim. One popular option is the Solution Finish Trim Restorer, which can nourish and restore faded plastic trim while also providing UV protection. To apply this product, start by using a microfiber applicator or foam applicator to apply a thin, even coat of the restorer to the plastic trim. Wipe off any excess product with a clean towel, and allow the plastic to dry for at least 6 hours. For best results, apply the restorer to a clean, cool surface in a well-ventilated area, and avoid getting it on the paintwork as it may cause damage.

Another option for UV-resistant trim shine is CarPro PERL, a water-based silicone-oxide dressing that can be used on plastic, engine, rubber, and leather surfaces. CarPro PERL provides UV protection and can be applied quickly and easily to black plastic trim. However, it is not a permanent solution and will need to be reapplied periodically.

In addition to these products, there are several other UV-protectant trim restorers available, such as CeraTrim, which offers strong restorative properties and lasting protection against UV rays. When applying any trim restorer, it is important to clean and prepare the surface of the plastic trim before application, and to work in a sheltered area to avoid rain or other contaminants.

While using a heat gun can be an option to restore black plastic trim, it is not recommended as it can cause more damage to the plastic in the long term. Instead, using a UV-resistant trim shine product can provide a more effective and lasting solution to restore and protect black plastic auto trim.

Painting with black spray paint

Before you start painting, ensure that the surface is completely clean. You can use a product like Fortador Gold Degreaser with a microfiber cloth to wipe away all the grime. It is important to note that the trim will need to be perfectly clean and decontaminated before painting.

If you want a glossy finish, apply a primer spray. However, a primer is not always necessary and depends on the type of paint and plastic surface you are working on. Carefully read the instructions on your chosen paint, as different brands may have specific requirements.

When you are ready to paint, make sure to stay away from any parts of the car that you do not want to paint black. Apply thin coats of paint to prevent bubbling or lifting. Most paints will require a couple of layers, so allow each layer to dry before applying the next.

If you want your paint job to last, consider using a clear coat spray or sealant. This will protect your trim from UV rays and prevent fading. Allow the paint to dry completely before applying the clear coat, and follow the manufacturer's instructions for best results.

It is important to note that painting your trim may not repair any real damage, and finding the right colour match can be challenging and time-consuming. There are also alternative methods to restore black plastic trim, such as using a heat gun or a plastic restorer.

Cleaning and re-treating

Cleaning

  • Start by giving your car a thorough wash, paying special attention to the black plastic trim. Use soap and warm water to remove any dirt, grime, or contaminants from the surface. A clean surface will ensure that the treatment absorbs better and prevents burning contaminants into the plastic when using a heat gun.
  • Dry the trim thoroughly with a clean microfiber cloth or towel. It is important to ensure that the trim is completely dry before moving on to the next step.

Re-treating

  • There are several products available for re-treating black plastic trim. You can use a plastic trim restorer, UV-resistant trim shine, or olive oil. You can also use a heat gun as a temporary solution to draw out the natural oils in the plastic, but this method may not be effective after multiple treatments.
  • If using a plastic trim restorer, follow the instructions on the product. Typically, you will need to apply the product to a clean, cool surface using a microfiber cloth or applicator pad. Spread the product evenly over the trim and allow it to dry.
  • If using olive oil, pour a small amount (about the size of a coin) onto a washcloth or paper towel. Rub the oil into the plastic using gentle, circular motions. Allow the oil to absorb for 5 to 10 minutes, then buff the surface with a separate dry towel.
  • For a more temporary solution, you can use a heat gun to draw out the natural oils in the plastic. Hold the heat gun several inches away from the surface and move it in small circles to avoid burning the plastic. Be cautious when using a heat gun, as it can easily damage the plastic if left in one place for too long.
  • After treating the trim, it is important to re-apply the chosen product regularly to maintain its effectiveness. Re-application frequency will depend on the product used and the exposure to sunlight and weather conditions.

By following these steps, you can effectively clean and re-treat your black plastic auto trim, restoring its natural colour and shine. Remember to re-apply the treatment as needed to protect your trim and maintain the appearance of your car.
