What You'll Learn

Use a premium protectant
Plastic trim pieces are susceptible to damage from harsh sunlight, rain, environmental contaminants, and harsh weather conditions. To prevent this, you can use a premium protectant to treat the plastic areas of your vehicle while they are still undamaged and unfaded.
A premium protectant will shield your plastic trim from UV damage, weathering, and chemicals, providing a long-lasting, professional-grade finish. It is important to note that not all protectants are created equal, and some may contain harsh chemicals that can damage your trim. Look for a product that is water-based and free of harsh ingredients.
When applying a premium protectant, start by washing your car as you normally would to remove any built-up dust, dirt, and debris. Then, using a clean foam applicator pad, massage the protectant into the pores and texture of the plastic trim surface. Ensure that you are treating all areas of the trim and allowing the product to fully penetrate the surface.
Once the protectant has been applied, let it set and dry for a few minutes. Finally, use a clean microfiber towel to wipe away any excess product. This will help ensure an even and streak-free finish.
By regularly applying a premium protectant to your vehicle's plastic trim, you can maintain a like-new appearance and protect it from the elements.

Apply a glossy polymer coating
To protect your car's interior plastic trim, you can apply a glossy polymer coating. This type of coating prevents cracks and fading by repelling harmful UV rays, which is essential as plastic trim pieces are susceptible to damage from sunlight exposure.
Glossy polymer coatings are designed to be quick and easy to apply, with a non-greasy, streak-free formula. They are typically sprayed onto the plastic surface and then wiped down, ensuring an even application. This simple process can be done on the go and will leave your car with a showroom-quality finish.
When applying a glossy polymer coating, it is important to ensure the surface is clean and free of any dirt, dust, or stains. You can use a product like Turtle Wax's All Surface Interior Detailer to remove any light stains and fingerprints from the plastic trim before applying the coating.
It is also recommended to regularly apply a protectant or dressing to your car's interior plastic trim to prevent future oxidation and fading. This can be done with a premium protectant or a quality trim dressing, which will restore the shine to your trim.
By following these steps and using the right products, you can effectively protect your car's interior plastic trim with a glossy polymer coating, maintaining its appearance and enhancing its longevity.

Use a trim restoration product
Using a trim restoration product is an effective way to protect your car's interior plastic trim. These products are designed to shield your vehicle from harsh sunlight, rain, environmental contaminants, and other damaging elements. Here are some tips on how to use trim restoration products for optimal results:
First, it is important to select a suitable trim restoration product. Look for products that are specifically designed for interior plastic trim. Some recommended products include Trim Kote, Turtle Wax Inside and Out Protectant, 303 Aerospace Protectant, Gyeon Preserve, and Dressle. These products offer UV protection and help prevent fading, cracking, and oxidation.
Before applying any trim restoration product, ensure that the plastic trim surface is clean and free from dust, dirt, and debris. You can use a microfiber cloth or a foam applicator pad to wipe down the surface and prepare it for treatment. It is crucial to follow the instructions provided by the product manufacturer for optimal results.
When applying the trim restoration product, wear disposable gloves to protect your hands. Work in small sections and apply the product evenly to the plastic trim. Massage the product into the pores and texture of the plastic surface, ensuring thorough coverage. Allow the product to dry completely before moving on to the next step or exposing the treated surfaces to any elements.
Some trim restoration products may require multiple coats or applications for optimal results. Always follow the specific instructions provided by the manufacturer. Once the trim is restored and protected, maintain its condition by regularly cleaning the plastic surfaces and reapplying the product as recommended.
By using trim restoration products, you can effectively protect your car's interior plastic trim, maintaining its like-new appearance and enhancing the overall aesthetics of your vehicle. Remember to follow the instructions and take your time during the application process for the best outcomes.

Apply a long-lasting dye
To protect your interior plastic trim, you can use a long-lasting dye to restore its colour and finish. This is a great way to enhance the appearance of your vehicle and boost its resale value.
One popular product is Trim Kote, a semi-permanent dye that works on unpainted plastic and vinyl trim. It bonds with the plastic, providing long-lasting colour restoration. It is recommended for black or grey plastic/vinyl surfaces and can be used on bumpers, mirrors, door handles, and more. Before applying Trim Kote, ensure the surface is clean and free of any dirt, dressings, waxes, or polishes. Use a shop towel or applicator to apply the dye evenly in small sections, allowing it to dry completely before moving on.
Another option is to use RIT Dye, which can be effective for smaller parts that can fit in a pan on the stove. You can mix this dye with acetone, which helps the dye seep into the pores of the material. However, be cautious as acetone has a low boiling point and can be dangerous if not handled properly.
Additionally, some automotive paint supply stores can mix paint to match your interior colour code. You can also use adhesion promoters to ensure the dye adheres well and does not chip off easily.
Remember to always work in a well-ventilated area when using dyes and wear disposable gloves to protect your hands.

Use a wax or ceramic application
Plastic trim pieces are exposed to harsh sunlight, rain, and environmental contaminants, which cause them to fade, crack, and dry out. To prevent this, you can use a wax or ceramic application to protect your car's interior plastic trim.
Waxes and ceramic coatings are designed to shield your car from the sun's harsh UV rays, road salts, bugs, and other oxidizing contaminants. These products can restore and protect plastic, rubber, and vinyl trim, leaving a protective coating. When choosing a wax, ensure it does not contain any polishing agents, as these can scratch soft plastics and trim.
Turtle Wax offers a range of products that can be used on interior plastic trim, including their Hybrid Solutions Pro Graphene Flex Wax and Hybrid Solutions Ceramic Spray Coating. Their Inside and Out Protectant is another option if you prefer less gloss on your plastic and trim. These products can be used on both the interior and exterior plastics of your car.
To apply wax or ceramic coating to your interior plastic trim, start by washing your car to remove any built-up dust, dirt, and debris. Use a high-quality wash mitt and a pH-balanced car wash soap. After washing, you can apply the wax or ceramic coating of your choice. Follow the product instructions for proper application and drying times.
In addition to waxes and ceramic coatings, there are other premium protectants and dressings available on the market specifically designed for plastic, rubber, and vinyl trim.
