Revamping Car Plastic: Diy Guide For Owners

how to renovate plastic on my car

Plastic is a common material in modern cars, used for everything from headlights to bumpers. However, it is susceptible to damage from the sun and harsh weather conditions, which can cause it to crack, fade, or discolour over time. Luckily, there are several ways to restore your car's plastic trim and prevent long-term damage. Some methods include using a plastic restorer product, applying heat with a heat gun, or treating the surface with olive oil, linseed oil, or WD-40. It's important to clean and dry the plastic surface before applying any treatment and to use a separate, soft cloth or towel to prevent scratching and residue buildup.

Using a plastic restorer

Plastic restoration products, such as Turtle Wax Black in a Flash Trim & Tyre Dressing, contain conditioning agents that reverse ageing and keep rubber and plastic trim soft and flexible. A good plastic restorer is also infused with powerful UV inhibitors that prevent damage from prolonged exposure to the sun.

To restore faded plastic trim to its original colour, you will need a trim restorer and a microfiber towel to massage the product into your car's interior. It is recommended to use an edgeless detailing cloth with a 300 GSM microfiber blend. This weight is ideal for a multi-purpose detailing cloth as it is durable enough to withstand countless restorations, yet plush enough for your vehicle's plastic trim.

Before applying the restorer, ensure the surface is clean and free of contaminants. Keep the towel used for restoration separate from other towels and tools to avoid damage from heavier soils.

After applying the restorer, allow the plastic to dry for 6 hours. Following the first application, your trim will stay black and looking new for approximately 8 months or more.

For a more straightforward approach, Car Throttle recommends using a heat gun to heat the plastic and draw out the oils within the material. However, this method can cause the plastic to warp, so it should be done with caution. After heating, treat the surface with olive oil, WD-40, or a trim restoration product.

Heat guns and olive oil

Using a heat gun on plastic car parts can restore their colour and shine. The heat from the gun draws out the natural oils in the plastic, bringing them to the surface and restoring the plastic's colour and shine. However, this method can weaken the plastic over time, as the oils oxidise. It is also a temporary solution, as the plastic will eventually fade again with use, and the treatment will become ineffective after several applications.

Before using a heat gun, it is important to clean the plastic surface to avoid burning contaminants into the plastic. It is also recommended to cover nearby non-plastic surfaces with a flame-resistant tarp, as the heat gun can warp or discolour them. When using the heat gun, only heat one area at a time to prevent damage.

Olive oil can also be used to restore the colour and shine of plastic car parts. It is most effective when applied to a clean surface, as it will absorb better. To apply, pour a coin-sized amount of olive oil onto a cloth or paper towel and rub it into the plastic. After a few minutes, buff the surface with a dry cloth to remove any excess oil.

For best results, you can combine the heat gun and olive oil methods. First, use the heat gun to draw out the natural oils in the plastic. Then, treat the surface with olive oil to enhance its colour and shine. This will also provide some protection against sun and rain.

It is worth noting that, while these methods can be effective, they are not long-lasting solutions. The colour and shine of the plastic will eventually fade again, and repeated treatments can further damage the plastic. For a more permanent solution, you may need to replace the plastic trim with a new piece.

Cleaning and protecting

When it comes to cleaning and protecting the plastic on your car, there are several methods and products you can use to restore its appearance and prevent future damage.

Firstly, it is important to clean the plastic surface thoroughly before applying any restoration products. Use a microfiber cloth or towel to wipe down the plastic, removing any dirt, stains, or other abrasive contaminants. Be sure to pay attention to intricate spaces such as air vents and dashboard crevices. It is recommended to use an interior detailer or a multipurpose cleaner and disinfectant for this step.

To restore the colour and elasticity of faded plastic trim, you can use a plastic restorer product. These products contain conditioning agents that reverse ageing and keep the plastic soft and flexible. Look for a restorer infused with UV inhibitors to protect against sun exposure and prevent future damage. Apply the restorer with a microfiber cloth or towel, massaging it into the plastic surface.

For black plastic trim, you can use a heat gun to draw out the natural oils and restore its lustre. However, this method is temporary, and repeated use may damage the plastic. Always start with a clean surface to avoid burning contaminants into the plastic, and be careful not to heat any area for too long. After using a heat gun, you can treat the surface with olive oil, WD-40, or a trim restoration product for added protection.

Another option for restoring black plastic trim is to use a plastic dye, such as Sem colour coat, which soaks into the plastic. Simply spray thin coats, allowing it to sit for about 10 minutes between intervals. You can also use black spray paint, but be sure to use a primer first to ensure the paint adheres properly.

To protect your plastic trim from future damage, consider using a UV protectant product, such as Solution Finish Over The Top Plastic Sealer. These products can be applied as a topper over trim restorers to enhance and extend their life. Be sure to follow the manufacturer's instructions for application and drying times.

By following these cleaning and protection tips, you can effectively restore and maintain the plastic on your car, keeping it looking like new.

Painting plastic

Preparation:

Before starting, it is essential to gather the necessary materials, including automotive paint suitable for plastics, a mask, primer, masking tape, clear lacquer, and microfibre cloths. It is also recommended to wear protective gear, such as gloves and eye protection, as some products can stain your skin and clothing.

Cleaning and Sanding:

Begin by thoroughly cleaning the plastic surface with a suitable cleaner, such as isopropyl alcohol, to remove any contaminants. If the plastic part can be removed from the vehicle, it is advisable to do so to ensure a more accessible and controlled painting process. Once the surface is clean, use sandpaper to smooth out any imperfections or "bobbles" on the plastic. Start with a lower grit, such as 150-grit, and gradually increase to finer grits like 800-grit and 1200-grit, to achieve a smooth finish. This process is crucial for textured plastics to ensure the paint adheres properly.

Priming:

Apply a suitable primer specifically designed for plastic surfaces. Ensure the primer is compatible with the type of paint you intend to use. You may need to use a flex primer for parts that are expected to flex, such as bumpers. Apply an extra coat of primer and allow it to dry.

Painting:

Select an automotive paint that is suitable for use on plastics. Spray paint is commonly used for painting plastic car parts. Before painting, mask off the surrounding areas of the car to prevent overspray. Use masking tape specifically designed for curved or straight edges, depending on the shape of the plastic part. Ensure there are no gaps for paint to seep through. Spray paint the plastic surface with slow and controlled movements, following the directions provided by the paint manufacturer. Allow the paint to dry according to the manufacturer's instructions.

Lacquering and Polishing:

Apply clear lacquer over the painted surface to protect the paint and enhance the shine. Apply four to five coats of lacquer, allowing each layer to dry for around 15 minutes before adding the next. Once satisfied with the finish, leave it to dry for a few hours before removing the masking tape. Finally, use a clean microfibre cloth to polish the plastic part. This will remove any loose debris and bring out a perfectly smooth and shiny surface.

Maintenance:

Remember that painted plastic car parts will require regular maintenance to maintain their appearance. Reapply paint or a protective coating as needed to prevent fading, cracking, or deterioration due to sun exposure and harsh weather conditions.

Professional detailing

Plastic restoration is a great way to improve the appearance of your car and protect it from further damage. Professional detailing can ensure the job is done to a high standard, preserving the longevity of your vehicle's plastic trim.

Professional detailers will often use plastic restorers, which are formulated to bring plastic, rubber, and vinyl back to life. These products are often water-based polymer formulas that contain special polymer additives to enhance performance and extend the longevity of the trim. They are designed to restore the colour and elasticity of the trim, while also protecting it from the elements.

Detailers may use products such as Turtle Wax Black in a Flash Trim & Tyre Dressing, which contains conditioning agents that reverse ageing and UV inhibitors to prevent sun damage. Other popular products include CAR GUYS Plastic Restorer, which is user-friendly and safe for auto detailing, and Torque Detail's Plastic Restore, which has a pleasant smell, is safe for fabrics, and achieves solid results.

The process of professional detailing involves preparing the surface by cleaning and removing any old dressings, oils, or dirt. This is followed by the application of the plastic restorer with a microfiber towel or foam applicator. The product is massaged or wiped onto the trim, and any excess is wiped off. The plastic is then left to dry for around 6 hours, restoring its colour and providing protection.
