It offers superior adhesion to various surfaces, including plastic, metal, rubber, and chrome. While some users have reported uneven results with Dupli-Color's vinyl/fabric paint, their Trim & Bumper Paint is a reliable option for those seeking a tough protective coating.

Application methods: spray paint, dyes with microfiber towels, and vinyl wrap

Spray paint is a common method for restoring black plastic trim. It is important to prepare the plastic surface before painting. The plastic should be scuffed and cleaned, and any cleaners, oils, or silicones should be removed with IPA (isopropyl alcohol). After preparation, the spray paint can be applied in thin, even coats. It is important to use a paint that is suitable for outdoor use and that works on plastics. Some users have reported success with products such as Rust-Oleum Trim and Bumper Paint, which has a rubberized texture when sprayed.

An alternative to spray paint is the use of dyes, which can be applied with microfiber towels or sponges. This method eliminates the need to worry about overspray. One such product is "That Black Stuff," which has received positive reviews for its effectiveness when the instructions are followed correctly.

Another option for restoring black plastic trim is to use a vinyl wrap. This method involves wrapping the plastic trim in a thin layer of vinyl, which can be purchased in rolls from hardware, automotive, or craft stores. It is important to ensure that the vinyl is of good quality and is thick enough to hide the texture of the plastic. Before applying the vinyl wrap, the plastic surface must be free of any wax, armor, or other substances that may prevent the vinyl from adhering properly. Some professionals have expressed concern about the long-term adhesion of vinyl wraps to plastic surfaces, so it is important to test the adhesion before proceeding.

A plastic trim restoration kit is another option that is typically easier than wrapping in vinyl and can make the trim look brand new. These kits often contain a trim restorer, such as Solution Finish Trim Restorer, which can be applied with a microfiber or foam applicator. After application, it is important to wipe off any excess product and allow the plastic to dry for at least six hours. A second application can provide even longer-lasting results.

Cleaning and preparation: wash with dish soap, wipe down with alcohol, and use prep soap

To prepare plastic for painting, it is important to ensure the surface is clean and free of any residue. This can be achieved by following a few simple steps:

Firstly, wash the plastic trim with dish soap and water. Fill a bucket with warm water and add a few pumps of dish soap to create a soapy mixture. For larger items, use a sponge to wipe down the surface. Ensure you squeeze out any excess water from the sponge if the item is electronic. Repeat this process until the dirt or old paint is removed. For smaller items, fully submerge them in the soapy water and use your fingers or a sponge to rub off any dirt or old paint.

Next, wipe down the plastic trim with alcohol. This step is especially important if you are dealing with water-based latex or acrylic paint. Apply the alcohol to a cotton ball and rub the surface until the paint is removed. This will ensure that any remaining paint residue is eliminated.

Finally, use a prep soap to clean the surface. This step will ensure the plastic trim is free of any remaining dirt or residue. For this step, you can use a non-abrasive, all-purpose cleaner. If you are dealing with tough stains, you can create a paste with baking soda and water, applying it to the surface and gently rubbing it with a damp sponge.

By following these steps, you will effectively clean and prepare your plastic trim for painting, ensuring a smooth and even surface for the best possible results.

Longevity: some products last longer than others, and some are more resistant to UV damage

Painting black plastic trim can be challenging due to the material's smooth surface and temperature responsiveness, making it prone to cracking and flaking. To ensure longevity, it is essential to select suitable products and follow the proper application techniques.

Firstly, when choosing a paint for black plastic trim, opt for those specifically formulated for plastics. These paints are designed to adhere well to the smooth surface of plastic and can withstand the expansion and contraction caused by temperature changes. Examples of popular paint brands for plastic include Krylon Fusion, Rust-Oleum Universal, and Rust-Oleum Painter's Touch 2X Ultra Cover. Additionally, look for paints with UV-resistant additives, especially if the trim will be exposed to direct sunlight, as this will help prevent discolouration and fading over time.

Applying a primer before painting is crucial for enhancing paint adhesion and longevity. Choose a plastic-specific primer and apply it evenly in light coats after the trim surface has been roughened with sandpaper and thoroughly cleaned. This extra step will help the paint adhere better and result in a more durable finish.

When selecting a paint finish, consider opting for a matte or satin finish, as glossy finishes are more susceptible to showing signs of UV damage over time. Additionally, avoid painting PVC trim darker than its original colour, as dark colours absorb more heat, which can lead to potential warping from heat expansion.

Finally, the application technique plays a vital role in the longevity of the paint job. Always follow the manufacturer's instructions for drying times and application techniques. Apply multiple light coats of paint, allowing each coat to dry completely before applying the next. This method helps prevent drips and ensures a smooth and even finish. Additionally, when applying the second coat of paint, spray in the opposite direction of the first coat to maximize coverage and minimize the visibility of the plastic underneath.

Fixing mistakes: Plasti-dip can be peeled off and redone

Plasti-dip can be a great way to paint your black plastic trim, but mistakes can happen. The good news is that if you're not happy with the result, or if you need to make corrections, Plasti-dip can be peeled off and redone. Here are some tips to help you fix any mistakes:

Identify the Issue:

First, identify the problem areas that need to be corrected. This could be uneven coverage, drips, or errors in the sprayed area.

Prepare the Surface:

Before reapplying Plasti-dip, it's important to ensure the surface is clean and free of any residue. Use a microfiber towel to wipe down the area and remove any dust or contaminants.

Peel and Smooth:

If the Plasti-dip is still fresh, you can try peeling it off carefully. Use a nitrile glove and coat your finger in xylene or naphtha to smooth out the edges of the peeled area. This will help create a more even surface for your next attempt.

Reapply Plasti-dip:

When you're ready to reapply the Plasti-dip, take your time and focus on maintaining an even distance from the surface and achieving consistent coverage. Ensure you have enough Plasti-dip product to create a thick enough coat that will be peelable in the future.

Alternative Methods:

If the Plasti-dip is stubborn and won't peel off easily, there are some alternative methods you can try. These include using products like WD-40, Goo Gone, or a dedicated spray from websites like dipyourcar.com. You can also try using a pressure washer, nylon brush, or brake cleaner to remove the Plasti-dip. However, always exercise caution when using these methods to avoid damaging the surface underneath.

Remember, practice makes perfect. Don't be discouraged if your first attempt at Plasti-dipping your black plastic trim doesn't go as planned. Learning from your mistakes and refining your technique will lead to better results the next time around.
