Black plastic on cars can be restored to its original colour in a number of ways. One method is to use a heat gun on a medium-low setting to heat the plastic, which draws oils to the surface and restores its colour. However, this is not a permanent solution and may damage the paintwork. A more permanent solution is to paint the plastic. This requires the use of a primer spray, paint, and a clear coat spray or sealant. Alternatively, there are products such as 'That Black Stuff' which can be wiped on to restore the black colour.
How to restore black plastic on cars:
| Characteristics | Values |
|---|---|
| Cause of damage | UV rays, road contaminants (e.g. small stones and sticks), and puddles of water mixed with dirt and grime |
| Prevention | Park car in the sun, use a heat gun on a medium-low setting, apply a protective coating, use a sealant, use a clear coat spray |
| Temporary fixes | Trim restorer, Armor All's plastic and vinyl repair product, Torque Detail Plastic Restore, That Black Stuff, Plastidip |

Using a heat gun to restore black plastic
Restoring black plastic trim on cars using a heat gun is a method that has gained some popularity. However, it is important to note that there are conflicting opinions on the effectiveness and potential damage caused by this method. While some people have reported success in restoring the colour of faded plastic trim using a heat gun, others have cautioned that it can lead to long-term damage to the plastic.
If you decide to use a heat gun for restoring black plastic trim on your car, here are some general steps and guidelines to follow:
- Park your car in a sunny area to get the plastic trim as hot as possible. Starting with a higher temperature will make the process faster.
- Set your heat gun to a medium-low setting. The goal is to heat the plastic evenly without melting it, so adjust the setting accordingly.
- Slowly and methodically apply heat to a small area at a time. Work in sections to ensure even heating.
- As the plastic heats up, you may see its natural deep black colour returning. This is due to the oils being drawn to the surface, and the crystal structure of molecules starting to move again.
- Be cautious when directing the heat to avoid excessive heat on paintwork, as it can cause the paint to bubble.
- Some people suggest applying car wax or automatic transmission oil after heating to restore shine and protect the surface.
It is important to note that while the heat gun method may provide temporary results, it can also make the trim look worse in the long term. Some sources suggest that it can accelerate the deterioration of the plastic, making it brittle and prone to further fading. Therefore, it is recommended to proceed with caution and consider alternative methods, such as using plastic trim restorers or paint specifically designed for car trim. These alternatives may provide more durable and long-lasting results without causing potential damage to the plastic.

Painting over the plastic
There are a variety of paints available for car trim, each with its own unique application process and finish. It is important to choose the right paint for your needs. For example, Rust-Oleum and Duplicolor offer spray paints suitable for car trim, with slightly different colours and application times. Most people opt for a flat black spray that is UV-resistant, offering protection from direct sunlight. Bumper/trim paint is another option, which adheres well even without a primer and is suitable for plastic bumpers and trim. If you are looking for a temporary solution, Plastidip is a good choice as it peels off easily, allowing for easy repainting.
Before painting, it is essential to prepare the surface properly. Clean the trim with a towel and cleaning solution to ensure any dirt, grime, or road contaminants are removed. If your trim has been neglected and is turning white due to oxidation, you may need to scrub it by hand or use a machine to remove as much of the oxidation as possible before painting.
When you are ready to paint, always read the instructions on the paint carefully. Some paints may require a primer, while others can be applied directly. Use the correct applicator pad, such as a microfiber or foam applicator, and carefully apply the paint to the car trim, being mindful of any areas you do not want to paint. To avoid bubbling or lifting, apply thin coats of paint, and if multiple layers are needed, follow the directions for the specific paint you are using.
To ensure the paint lasts and maintains its colour, consider using a clear coat spray or sealant after the paint has dried. This will provide additional protection and help maintain the appearance of your freshly painted car trim.

Using a plastic trim restorer
It is important to clean the trim thoroughly before applying a restorer and protectant. Even if the trim looks clean, there may be tiny contaminants that are invisible to the naked eye, causing the original colour to appear dull and faded. A quick wipe-down with a detailer like Hybrid Solutions Streak-Free Interior Mist can make a huge difference in the overall quality of the finish.
After cleaning, you can apply the plastic trim restorer. Some products, like Solution Finish Trim Restorer, require you to use a microfiber applicator or foam applicator to apply the product onto the plastic. After wiping off the excess product with a clean towel, you must allow the plastic to dry for 6 hours. Other products, like Turtle Wax Black in a Flash Trim & Tyre Dressing, can be massaged into the car's interior using a microfiber towel.
In addition to using a plastic trim restorer, you can also use a heat gun to restore black plastic trim. This method involves heating the plastic to draw out the oils within the material. However, it is important to be cautious when using this method, as it is easy for the plastic to warp or melt. It is recommended to start with a clean or freshly-washed surface to avoid burning contaminants into the plastic and to heat one area at a time to prevent damage. After using a heat gun, you can treat the surface with olive oil, WD-40, or a trim restoration product to make the surface darker and protect it from sun and rain.

Removing oxidation
Scrubbing and Cleaning
Before attempting any restoration techniques, it is essential to start with a clean surface. Use a brush, wash mitt, or machine scrubber to remove dirt and grime from the plastic trim. This step is crucial as it prepares the surface for the next steps and ensures that any products applied will be more effective.
Chemical Cleaners and Dressings
There are various chemical cleaners and dressings specifically designed for removing oxidation from plastic trim. Look for products that claim to restore and reverse oxidation, such as Solution Finish, or those that are plastic or carbon-based for more permanent results. Be sure to read the labels and instructions to understand the proper application process and expected results. Some popular products include Koshi covers, Plexus, and Wolfgang car care products.
Polishing and Rubbing Compounds
For black plastic trim with a matte finish, consider using a polishing or rubbing compound. These compounds can help restore the original colour and shine of the plastic. However, compounding can be less successful and more difficult on complex surfaces, so repainting may be a more feasible option.
Heat Gun Method
Park your car in the sun or use a heat gun on a medium-low setting to heat the plastic trim. This method draws the oils to the surface, restoring the natural deep black colour. However, use caution as excessive heat can damage the paintwork, and this method may not provide long-lasting results.
Painting
If all else fails, consider painting the plastic trim. Paint offers a more permanent solution as it does not fade like plastic. Choose a paint that matches the original colour and finish of your trim, such as flat black spray paint. Ensure the paint is UV-resistant to protect the trim from direct sunlight.
It is important to note that preventing oxidation is just as crucial as removing it. Regular cleaning and maintenance of your car's plastic trim can help slow down the oxidation process and maintain the trim's original appearance.
