Faded black plastic trim can make your car look older than it is. UV rays are one of the main causes of deterioration, dehydrating and degrading the plastic trim. Other factors include road contaminants like small stones and sticks, and puddles of water mixed with dirt and grime. There are various ways to restore black plastic trim, including using a heat gun, car trim restorer, or a plastic restorer.

Using a heat gun to draw out oils
There are several risks associated with using a heat gun to restore black plastic trim. Firstly, the intense heat can cause irreversible damage to the plastic, including melting, warping, and brittleness, which can ruin its appearance and structural integrity. Secondly, if the plastic trim is near painted surfaces, the heat can cause paint bubbling or peeling, leading to additional repair expenses. Finally, using a heat gun can also be a safety hazard if not used properly. Therefore, it is generally recommended to use specialised restorer products and techniques for effective and safe restoration.
To extend the lifespan of the trim after using the heat gun method, it is important to take preventive measures. This includes applying a UV protectant or plastic sealant to prevent sun damage and shield the car from direct sunlight by parking in a shaded area or using a car cover. Regular cleaning and maintenance of the trim can also help to maintain its appearance. However, it is important to avoid harsh chemicals and automatic car washes that can strip protective coatings and accelerate fading.
While the heat gun method can be effective in restoring the colour and shine of black plastic trim, it is not a permanent solution. The natural oils in the plastic will eventually deplete, causing the trim to fade again. Therefore, it may be necessary to repeat the process or explore other restoration methods, such as using a plastic restorer or trim restoration product, to maintain the desired appearance.
Overall, using a heat gun to draw out oils can be a quick and budget-friendly solution for reviving automotive black plastic trim. However, it is important to be cautious of the potential risks and take appropriate preventive measures to maintain the results. For a more permanent solution, it is recommended to use specialised restorer products designed for black plastic trim.

Applying oil to the surface
The use of oil is a popular method for reviving automotive black plastic trim. It is a relatively long-lasting solution, and there are a variety of oils that can be used, including boiled linseed oil, olive oil, and WD-40.
To apply oil to the surface of the trim, start by ensuring that the surface is clean and dry. Use a clean cloth or towel to apply the oil to the faded areas. It is important to use a small amount of oil, as a little goes a long way. Rub the oil into the plastic until it is fully absorbed. Allow the oil to soak for five to ten minutes.
After the oil has had time to absorb, use a separate dry towel to buff the surface lightly using rapid circular motions. Turn the towel over and give it a final buff to remove any excess oil. This process will help to restore the rich black colour of the trim and provide some protection against sun and rain.
It is important to note that this method is not a permanent solution. The oils will eventually start to dry out, causing the trim to fade again. Therefore, it is recommended to reapply oil at least weekly or before the start of each season to maintain the desired appearance. Additionally, be cautious when using a heat gun to draw out oils, as it can cause the trim to look worse in the long term and accelerate deterioration.

Using a plastic restorer
For example, when using Torque Detail Plastic Restore, it is recommended to first wash the car, following an exterior detailing guide for a complete wash. Then, spray the plastic restorer generously onto the plastic trim, ensuring that all areas are covered. Allow the spray to sit for at least 30 seconds, but ideally 60 seconds, so that it can sink deep into the plastic and change its molecular structure. Finally, use a clean microfiber towel to wipe away any excess liquid, ensuring that all panels, creases, and valleys are dry.
Another popular product, Solution Finish Trim Restorer, also requires cleaning the plastic trim first, ideally with isopropyl alcohol, leaving only bare plastic. Then, use a microfiber or foam applicator to apply the product onto the plastic. Again, wipe off any excess product with a clean towel and allow the plastic to dry for 6 hours. After the first application, the trim will stay black for approximately 8 months or more, and a second application can make it last even longer.
It is important to note that while these products can effectively restore black plastic trim, they are not permanent solutions. The plastic will eventually turn grey and dull again, and repeated applications of these products can further damage the plastic. Additionally, some products may only last a few wash cycles or days of rain, so it is important to incorporate them into your car washing and cleaning regimen.

Repainting
Before painting, ensure the trim is clean and dry. You can use a cleaning solution to wipe down the trim. If there is any residue, use isopropyl alcohol to clean the surface, leaving only bare plastic. If you are using a primer, apply it before the paint. Carefully apply the paint, ensuring you do not stay in one place too long, as you could end up warping the plastic.
After painting, seal the trim with a clear coat for a glossy finish. You can also use a product like Solution Finish Over The Top Plastic Sealer, which protects the trim from harmful UV rays and prevents fading. This can be used as a standalone treatment on new or good-condition plastics, or as a topper on plastics that have been restored with Solution Finish Trim Restorer.

Using a UV protectant
The sun's UV rays can cause plastic to fade, crack, and dry out. Plastic contains oils, and when UV rays are absorbed by plastic, the UV energy excites electrons, creating free radicals that cause the polymer structure to break down. This results in the plastic losing its deep black finish. To prevent this, you can use a UV protectant.
UV protectants are products that are applied to the trim to prevent sun damage. CarPro PERL is a water-based silicone-oxide all-purpose dressing that can be used on plastic, engine, rubber, and leather surfaces. It provides UV protection and can be applied quickly and easily. However, it is not a permanent solution and will need to be reapplied.
Meguiar's Ultimate Black Plastic Restorer is another popular option that can be used on exterior plastic, vinyl, and rubber trim. It uses advanced hybrid polymer technology to seal non-porous surfaces with UV protection. The formula dries almost instantly, is non-greasy, and will not streak if it gets wet. Meguiar's recommends applying the product monthly for the best results.
Another option is to use a heat gun to draw out the oils already present in the plastic and bring them to the surface to restore its appearance. However, this is not a permanent solution as the natural oils will eventually deplete again. After using a heat gun, you can apply a UV protectant to maintain the results.
When choosing a UV protectant, look for a product that offers long-term durability and protection against UV rays and external contaminants. It is also important to keep your car protected against the elements and to shield it from direct sunlight by using a car cover or parking in a shaded area.
