Black Plastic Trim: Detailing For A Fresh Look

how to detail black plastic trim

Keeping your car's black plastic trim looking new is a challenge, as over time, the trim will inevitably lose its deep black colour and fade to grey or white. This is caused by the sun's UV rays, which dehydrate and degrade the plastic, and contaminants from the road, which speed up the degradation process. Luckily, there are several ways to restore black plastic trim and keep your car looking its best.

Using a heat gun

When using a heat gun, it is recommended to set it to a low or medium setting to avoid warping the plastic. Hold the heat gun about 3 inches away from the surface of the plastic and move it in slow, sweeping motions, ensuring even heat distribution. It is important to work slowly and use an even pattern to avoid spotty or splotchy results. Power washing the plastic trim before applying heat can also help prevent blotchy results caused by years of cleaning products.

It is also crucial to keep the heat gun constantly moving and avoid stopping or slowing down too much. This method should only be used a few times, as each application can make the plastic more brittle and prone to cracking and breaking. Additionally, be cautious when working near the gas cap, as heat guns can pose a safety risk in certain areas.

While the heat gun method can be effective in restoring the appearance of black plastic trim, it is not a long-term solution. The results may last from a few weeks to a year or more, depending on the specific plastic's chemical makeup and the environment and exposure. For a more permanent solution, it is recommended to use a high-quality trim restorer or rejuvenation product that penetrates the plastic's surface and provides UV protection.

Overall, using a heat gun to detail black plastic trim can be a quick and budget-friendly fix, but it is important to understand its limitations and potential drawbacks to make an informed decision.

Cleaning with isopropyl alcohol

To detail black plastic trim, cleaning with isopropyl alcohol is a recommended method to remove any residue, cleaners, oils, or silicones from the plastic. It is important to note that isopropyl alcohol should not be used on painted or glass surfaces. If isopropyl alcohol is accidentally applied to these areas, wipe it off immediately with a clean towel.

Before using isopropyl alcohol, ensure you are working in a well-ventilated area and are wearing protective gloves and eyewear. To begin the cleaning process, shake the bottle of isopropyl alcohol well. Apply a small amount of the liquid to a microfiber sponge or applicator pad. Spread a thin, even coat of the isopropyl alcohol over the plastic trim, ensuring complete coverage. Allow the isopropyl alcohol to penetrate the surface for 3 to 4 minutes.

After the waiting period, use a clean microfiber towel to buff off any excess isopropyl alcohol. Ensure you also wipe off any nearby glass or painted surfaces to avoid accidental damage. Once the isopropyl alcohol has been applied and buffed, the trim is ready for the next steps in the detailing process, such as applying a trim restorer or sealant.

It is important to note that while isopropyl alcohol is effective for cleaning and preparing the surface, it should be used with caution. In some cases, it may remove the protective coating on plastic trim, resulting in a chalky or ashy appearance. Therefore, always test on a small area first and exercise caution when working with this substance.

Applying a trim restorer

To apply a trim restorer, it is important to first clean the trim thoroughly with isopropyl alcohol to remove any residue or cleaners, oils or silicones from the plastic. Use a microfiber applicator or foam applicator to apply the restorer evenly. Wipe off excess product with a clean towel and allow the plastic to dry for 6 hours. For best results, apply to a clean, cool surface in the shade.

There are many different products that can be used to restore black plastic trim. Some popular products include Solution Finish Trim Restorer, Torque Detail Plastic Restore, and Black Wow. Solution Finish Trim Restorer is a trim dye that will last months after application. Torque Detail Plastic Restore penetrates the plastic's surface, replenishing lost oils and providing UV protection. Black Wow is a small but effective bottle that will make you say "wow."

Another option is to use a finishing product such as Torque Detail Ceramic Spray, which builds an invisible and durable ceramic layer on top of your car's finish. It provides an ultra-premium shine that lasts for up to 12 months and forms a barrier against road contaminants and UV rays that cause plastics to fade.

If you are looking for a more natural solution, peanut butter can be applied to the trim as a polish and then wiped away with a clean cloth. The high fat content in peanut butter helps to restore oils to the plastic's surface. However, it is important to note that the oils in peanut butter are different from the oils in plastics, so it will not restore them on a molecular level. Additionally, it can be messy and leave a strong scent.

For a more permanent solution, you can use a heat gun to gently heat the plastic and bring out the oils within the material, restoring the colour. However, this method can warp the plastic if you are not careful, and the trim will eventually turn grey and dull again.

Using a paint thinner

Paint thinner can be used to detail black plastic trim on cars. Over time, the oils near the surface of plastic trim pieces degrade and dry out, leading to discolouration. Plastic trim pieces do not have a protective clear coat, so they are susceptible to damage from the elements, such as UV rays from sunlight, harsh weather, and road debris. This damage can cause black plastic trim to fade to a dull grey colour, making your car look older than it is.

Paint thinner can be used to remove oxidation buildup and strip away old, crusty polish, leaving a clean surface underneath. However, it should be used cautiously as it may damage the plastic if over-applied and it is not guaranteed to be safe for plastics. To use paint thinner, dampen a microfiber cloth with a small amount of the substance. Gently wipe the affected areas in small sections, immediately wiping off any excess with a clean, dry towel.

After using paint thinner, it is important to apply a UV protectant to prevent further fading. While paint thinner can be effective for removing oxidation buildup, it does not restore the colour of the plastic itself. For a more permanent solution, a high-quality trim restorer can provide effective and lasting results. These products penetrate the plastic's surface, replenishing lost oils and providing UV protection.

Before applying a trim restorer, clean the trim thoroughly with isopropyl alcohol to remove any residue. Use a microfiber applicator to apply the product evenly and allow it to absorb for a few minutes before buffing off any excess residue. Let the trim restorer cure for at least six hours before exposing the trim to moisture. With proper maintenance, this method can keep plastic trim looking new for up to a year.

Applying a ceramic spray

To detail black plastic trim, you can use a ceramic coating spray. This method is a cost-effective, long-term solution that restores the pigment to plastic trim and provides protection from UV rays.

Adam's Ceramic Black Trim Restorer is a popular product that can be used to achieve this. The product is a ceramic coating infused with black dye that penetrates plastics to leave a rich, dark finish. It is also a semi-permanent dye that colours faded black trim back to a like-new appearance. The application process involves the following steps:

  • Thoroughly clean the plastic trim with a trim cleaner, such as Adam's Eco All-Purpose Cleaner, to remove any dirt, grime, or contaminants.
  • Prep the surface with a surface prep solution to remove any films left behind from cleaning.
  • Use a suede applicator pad or a microfiber applicator pad to apply the ceramic coating spray. Ensure that you follow the manufacturer's instructions for the specific product you are using.
  • During the application, cover all trim surfaces thoroughly and follow any directions provided by the manufacturer.
  • Allow the product to dry and cure. The curing process may vary depending on the product, but some products can take up to six hours or more to fully cure.

Another product mentioned in a forum is Gyeon One ceramic coating, which the user applied to black plastic trim without any issues. However, it is important to note that some users have expressed concerns about using ceramic coatings due to potential streaking issues and other negative experiences. Therefore, it is crucial to research and follow the manufacturer's instructions carefully when applying any ceramic coating product.
