Cleaning the plastic interior

Firstly, it is crucial to select an appropriate cleaner. There are various options available, including all-purpose cleaners, car-specific cleaners, and interior detailing cleaners. Some popular choices include Simple Green, Meguiars, Mothers, Turtle Wax, and Chemical Guys. These products are easily available at auto stores and can effectively remove dirt and grime from plastic surfaces.

Before you begin the cleaning process, ensure you have the right tools. You will need a lint-free cloth or a brush, depending on the texture of the plastic surface. It is also recommended to use a car-safe window cleaner for gloss areas. If you plan to clean fabric seats or carpets, have some liquid laundry soap on hand as well.

Now, let's move on to the cleaning process. Start by diluting your chosen cleaner with water, following the product's instructions or recommendations from other users with similar cars. Be cautious when applying the cleaner to electronic components, and avoid drenching them. Use your cloth or brush to gently scrub the plastic surfaces, paying extra attention to areas with wrinkles or textures that tend to collect dirt.

For a deeper clean, consider using a generic tap water and dish soap mixture. A few drops of palmolive or a similar product can effectively cut through finger grease and grime. Finish the process by using a lint-free cloth and a car-safe window cleaner on gloss areas to ensure a streak-free shine.

Finally, remember that a thorough cleaning process is essential when preparing to change the colour of your car's plastic interior. Ensure that you remove all previous treatments, such as Armor All, to create a surface that allows the new colour to adhere properly.

Choosing the right primer and paint

Painting the plastic fixtures on a car is a great way to revitalise its appearance. It can be a cost-effective way to customise your car's interior and give it a fresh, new look.

When it comes to choosing the right primer and paint, there are a few things to consider. Firstly, it's important to select a primer that is suitable for the surface you are working on. In this case, you will need a primer that is specifically designed for automotive plastics. These primers are formulated to improve the adhesion of the paint to the plastic surface, resulting in a longer-lasting finish. Look for a high-build primer or a primer that is high-filling and sandable, as these will help fill in any minor scratches or imperfections on the plastic surface. You will also want to choose a primer that lays down as a thin, smooth coat, allowing you to apply paint on top in a relatively short time.

Another factor to consider is whether you are repairing or refinishing the plastic surface. If you are repairing, you will need a primer that can conceal any minor scratches, halos, or other imperfections. For small spot jobs, an aerosol primer is a good option as it is cost-effective and quick-drying. For larger repairs, a catalysed primer is a better choice as it offers higher quality and better gloss retention.

When choosing the paint, it is important to select a type that is specifically formulated for automotive applications and plastic parts. Automotive-grade paints have good adhesion properties and are resistant to chemicals and UV radiation, preventing the painted plastic parts from cracking, fading, or deteriorating. You can choose from a variety of colours and finishes to achieve the desired look, such as gloss or matte. Additionally, consider using a clear coat over the paint to add extra protection and enhance the gloss.

It is also important to follow the manufacturer's instructions for both the primer and paint. This includes properly preparing the surface, allowing adequate drying and curing times, and maintaining the recommended spraying distances and techniques. By taking the time to choose the right primer and paint, and following the necessary application steps, you can achieve a professional and long-lasting finish for your car's plastic interior.

Removing interior panels

First, it is important to gather the necessary tools. The specific tools required may vary depending on the make and model of your car. For example, if you have an older vehicle with hand-crank windows, you will need a special tool to reach the ring behind the crank. Other common tools needed include screwdrivers, pliers, and plastic panel tools such as a pull-type remover, a narrow-edge remover, and an upholstery clip remover.

Before removing any panels, it is crucial to consult the proper repair manual to understand the technical aspects of the process and be aware of any electrical components or connections behind the panels. This step will help you avoid creating any unnecessary problems. Additionally, always ensure that you have adequate ventilation when working with your car's interior, and wear appropriate safety gear like gloves and a mask.

Now, let's begin the removal process. If you are working with a door panel, use the appropriate plastic panel tool to separate the panel from the clips. Then, simply lift the panel up and out. For dashboard panels, the process is a bit more involved. First, disconnect the negative battery cable to prevent any electrical damage. Open the glove box and unhook any clips or fasteners, then set the glove box aside. Locate the screws on the lower panel of the dashboard and undo each one, causing the panel to separate. Finally, disconnect the faceplate for the audio system using a screwdriver and the appropriate remover tool.

When removing panels with windows, the process may vary depending on whether you have power windows or hand-crank windows. For power windows, use a Phillips-head screwdriver to remove the screws holding the panel in place. Set the screws and protective covers aside, then remove the remaining screws, except for the plastic ones, which can be pulled out with pliers. Once all screws and covers are removed, hold the panel on both sides and pull it free. For hand-crank windows, use the special tool to reach behind the crank and remove the ring. Separate the crank from the panel before proceeding with screw removal.

Remember, always take your time and work carefully to avoid damaging your car's interior panels during the removal process. With the right tools and precautions, you can successfully remove the panels and proceed with your colour-changing project.

Using vinyl wraps

Vinyl wraps are a great way to change the colour of your car's plastic interior. They are adhesive-backed plastic sheets that can be applied to most smooth surfaces, including plastic, metal, and glass. Vinyl wraps offer a wide range of colours, patterns, and finishes, allowing car owners to achieve a personalised look for their vehicle's interior.

When selecting a vinyl wrap, it is important to consider the material type, texture, finish, durability, thickness, and colour or design. Vinyl wraps come in various materials, such as carbon fibre, leather, matte, gloss, and more. You can choose a texture and finish that complement the car's overall style and your personal preferences. It is also important to select a durable and thick vinyl that can withstand daily use and potential wear and tear.

Before applying the vinyl wrap, it is recommended to start with small, less complex areas to get a feel for the process. You will need a drop cloth or plastic sheeting to protect the surrounding area from adhesive residue or accidental cuts. A spray bottle with soapy water can be used to create a solution that allows you to slide and adjust the vinyl before it fully adheres. Some installers also use a lubricant or gel to help position the vinyl without it sticking prematurely. It is important to wear a respirator or mask when cutting or heating the vinyl to protect yourself from fumes or particles.

Vinyl wraps are easy to clean and maintain. Regular cleaning can be done with mild soap and water, making it a hassle-free option for busy car owners. Vinyl wraps are also resistant to stains and spills. However, it is important to avoid using harsh chemicals or solvents, as they can damage the vinyl.

Eventually, your vinyl wrap will degrade, but removing it is a simple task. You can use a heat gun and adhesive remover to loosen the adhesive and pull it off. Vinyl wraps can typically be removed without causing damage to the underlying surface, but it is important to follow proper removal techniques and use the right tools.

Applying a clear coat

Clean the Surface

Start by cleaning the plastic surface thoroughly. Use a suitable cleaner, such as PRE Paint Prep, and a lint-free rag to wipe down the surface. This will help remove any contaminants, such as oils, dirt, or road debris, that could ruin your clear coat.

Heat the Surface (Optional)

If desired, you can use a heat gun to warm the surface of the plastic. This helps to "cook out" any contaminants that may be trapped in the pores. Be sure to maintain a medium heat and keep the gun moving to avoid damaging the surface.

Abrade the Surface

Lightly abrade the surface using a scuff pad or fine-grit sandpaper. This creates a rough texture that helps the clear coat adhere better. If you don't want to risk scratching the surface, opt for a non-woven scuff pad. You can also use a woven pad along with your paint prep cleaner to both clean and abrade the surface simultaneously.

Apply an Adhesion Promoter (Optional)

If the plastic surface is flexible or subject to a lot of movement or abuse, it's recommended to apply an adhesion promoter before the clear coat. This will help the clear coat bond better and prevent flaking or peeling during normal use. Bulldog Adhesion Promoter is a popular choice for plastic surfaces.

Apply Light to Medium Coats First

When applying the clear coat, start with light to medium coats first. Gradually build up the thickness with subsequent coats, staying within the recoat window. This helps ensure a smooth and even finish.

Add a Flex Agent for Flexible Plastics

If you're working with extremely flexible plastics, consider adding a small amount of flex agent to the final coats of your clear coat. Mix the flex agent according to the manufacturer's specifications, and be sure to test spray before starting for better results.

By following these steps and choosing the right products, you can successfully apply a clear coat to your car's plastic interior, protecting the surface and enhancing its appearance.
