Plastic is a common material in modern cars, used for everything from headlights to bumpers. However, age, sun exposure, and other factors can cause plastic trim to fade over time, making your car look older and less appealing. Fortunately, there are several ways to restore faded auto plastic and improve your car's appearance. Some methods include using household items like olive oil or WD-40, while others involve specialised products like plastic restorers, sealants, and ceramic coatings. More complex techniques, such as using a heat gun or sandpaper, can also be employed. With the right techniques and products, you can restore your car's plastic trim to its original shine.

Clean the plastic trim with soapy water and a microfiber towel
To restore faded auto plastic, it is important to start with a clean surface. This will ensure that any products used to restore the plastic can properly bond with the plastic.
First, fill a bucket with soap and water. Then, dip a microfiber towel into the soapy water and wring it out. Next, wipe down the plastic trim with the damp microfiber towel, ensuring that you remove any surface grime, dust, and dirt. Rinse the trim with clean water and wipe it dry with a microfiber towel.
It is important to note that you should not use a heat gun on the plastic trim until it has been cleaned, as burning contaminants into the plastic can cause damage. Additionally, if using sandpaper to restore the plastic, it should also be dipped in soapy water before use.

Use a heat gun to gently heat the plastic, bringing out the oils
Using a heat gun to gently heat the plastic is a popular method to restore the colour of faded auto plastic. This method works by bringing out the oils within the plastic material.
Before using a heat gun, it is important to clean the plastic surface with soap and water to remove any dirt or debris. This step is crucial because heating dirty plastic can burn in any dirt or stains, which may discolour the plastic. Once the plastic is clean, dry it off with a towel.
When using the heat gun, always start with a clean or freshly washed surface to avoid burning contaminants into the plastic. Cover any nearby non-plastic objects or surfaces with a flame-resistant tarp to protect them from the heat, as the heat gun can warp or discolour non-plastic surfaces. Set the heat gun to the lowest heat setting and hold it 6-10 inches away from the plastic surface. Turn on the heat and move the heat gun around the plastic, ensuring you don't hold it too long in any single section to prevent damage. Continue this process for 30-45 seconds, heating the plastic until it turns to a darker, richer colour.
As you heat the plastic, you are essentially melting the surface, which brings out the oils from within the plastic to the surface, making it look new again. This process works because most plastic is made from fossil oil, and these oils can be drawn out to restore the colour and shine of the plastic. However, it is important to note that this method may not work on all types of plastic, and repeated treatments can eventually turn the plastic grey.

Treat the surface with olive oil, WD-40, or a trim restoration product
To correct faded auto plastic, you can treat the surface with olive oil, WD-40, or a trim restoration product. Here is a detailed guide on how to do it:
Olive Oil Treatment:
Firstly, wash the plastic surface thoroughly. Then, apply a small amount of olive oil to a rag, and rub the plastic in a circular motion. Use a dry rag to wipe away any excess oil, ensuring that the surface is not too slick. Olive oil is a simple and straightforward solution, and it will not harm the plastic. However, it may start to smell rancid after a few months. To mitigate this, allow the treated surface to air out for a day.
WD-40 Treatment:
WD-40 is a water-displacing spray that can be used to treat faded auto plastic. While it is not specifically mentioned in the sources provided, it is a common household item often used for various purposes, including automotive maintenance. It is important to follow the instructions on the product label and take the necessary precautions when using any chemical product.
Trim Restoration Products:
There are various trim restoration products available, such as Solution Finish Trim Restorer and Feynlab Plastic V2. These products are designed to restore and protect faded automotive plastic trim. Before applying any product, ensure the surface is clean and free of residue. Some products may require multiple coats and curing time between applications. Always refer to the instructions provided by the manufacturer and take the necessary safety precautions, such as wearing gloves and eye protection.
By following these treatments and using the appropriate products, you can effectively correct faded auto plastic and enhance the appearance of your vehicle.

Seal the plastic trim with a UV protectant to prevent fading
To prevent fading, it is important to seal the plastic trim of your car with a UV protectant. Plastic trim can fade due to repeated washings, weather exposure, age, and sun exposure. UV rays can cause long-term damage to plastic trim, and sealants can help prevent this.
There are several products available to seal and protect plastic trim from UV damage. One option is to use a plastic restorer, such as Solution Finish Trim Restorer, which can restore the plastic's original colour and protect it from future fading. This product can be applied with a microfiber or foam applicator and will last for several months. Another option is to use a heat gun to heat up the plastic and draw out the oils within the material. However, this method can be risky as it can easily warp the plastic. After using a heat gun, it is recommended to treat the surface with olive oil, WD-40, or a trim restoration product for added protection.
Additionally, there are various UV protectant products available that can be applied to the plastic trim. Popular options include 303 Aerospace Protectant, Gyeon Trim, and Turtle Wax Ice with UV Protectant. These products can help protect the plastic trim from the damaging effects of UV rays and keep it looking new. It is important to note that some UV protectants are better suited for interior or exterior use, so choose a product that is appropriate for your needs.
For a more permanent solution, you can use a plastic sealer like Solution Finish Over The Top Plastic Sealer, which can be used as a standalone treatment on new or well-maintained plastic trim. This product fills the void in the detailing product industry as a long-lasting UV protectant for plastic. It does not need to be reapplied after every car wash, making it a convenient and effective option.
By sealing the plastic trim with a UV protectant, you can prevent fading and maintain the appearance of your car's plastic trim. These products offer a range of benefits, from temporary solutions that restore the original colour to permanent sealants that protect against future damage.

Paint the plastic if other methods are ineffective
If other methods are ineffective, you can paint the plastic to restore its colour. There are several paint products available for this purpose, such as ColorBond Pro Tech Trim Color, which is designed to bond with automotive trim and provide a durable and long-lasting finish. It is also economical and easy to use. Before painting, clean the plastic with soap and water, then mask the surrounding areas with tape to protect them from paint. Lightly sand the plastic with wet-dry sandpaper (1200 grit) to prepare the surface for painting.
For the best results, apply a spray-on adhesion promoter, such as ColorBond Clear Adhesion Promoter, before painting. This will enhance the adhesion of the paint to the plastic surface. Then, apply the paint in light mist coats, adding additional coats as necessary. ColorBond Pro Tech Trim Color is available in various colours, including black, silver, charcoal, titanium, and white, so you can choose the one that best matches your car's trim.
Another option for refinishing faded car interior plastic is ColorBond LVP. This paint is designed to bond with leather, vinyl, and plastic, and it remains flexible to adhere to the surface as it flexes, expands, and contracts. This helps prevent cracking and peeling. Before applying ColorBond LVP, clean the interior plastic with ColorBond Prep Cleaner and mask any areas you don't want to paint. Then, apply the paint with light mist coats, adding additional coats as needed.
It is important to note that painting should be a last resort, as it may not always be necessary. There are other methods to restore faded auto plastic, such as using a heat gun, olive oil, or other dressings, which can effectively reduce the appearance of oxidation and restore the colour of plastic trim. However, if these methods do not produce the desired results, painting can provide a more permanent solution.
