What You'll Learn
Using Rit Dye
Rit Dye is a cheap option for customising your car's plastic parts without the need for paint or custom parts. Rit Dye is typically used for fabric but it also works well for dyeing plastic. It is available in powder or liquid form and can be found in the laundry aisle of your local supermarket or department store.
Before dyeing, ensure that your plastic parts are clean. Any dirt, grime or oil can cause discolouration. You can use a product like Simple Green to degrease the parts and then use light sandpaper to scuff the surface for better paint adhesion.
For the dye bath, you can follow the instructions on the bottle of Rit Dye for mixing the powder or liquid dye. Alternatively, you can pour the dye directly into your plastic dyeing container for deeper colours. If you are using a stove-top method, pour the dye into a saucepan and bring it to a rolling boil. Reduce to a simmer and carefully submerge the plastic parts into the dye bath, stirring constantly. Check the parts regularly for their desired coloration.
Once the desired colour is reached, carefully remove the parts from the dye bath and let them cool before rinsing them under cold water. After rinsing, set the parts aside to dry. The dyeing process typically takes 15-60 minutes, depending on the type of plastic. Some colours or kinds of plastic may take longer. If the pieces are not as dark as desired, you can put them back into the dye bath for a few more minutes.

Prepping the plastic
Cleaning the Plastic
Start by thoroughly cleaning the plastic surface to remove any dirt, grease, or residue. You can use a dedicated plastic cleaner or a degreaser like Simple Green. For a more intensive clean, use a grey scuff pad along with the cleaner, paying close attention to textured or recessed areas. Rinse with water or wipe away any residue with a damp cloth, and let the surface dry completely.
Scuffing the Surface
Once the plastic is clean, use light sandpaper to scuff the surface lightly. This step helps create a rougher surface for the dye to adhere to. It also helps remove any remaining residue that may hinder the dyeing process. Make sure to scuff evenly and not apply too much pressure to avoid creating deep scratches.
Applying Adhesion Promoters
To promote better adhesion of the dye, use an adhesion promoter specifically designed for plastics. SEM offers products like Sand Free and Adhesion Promoter that soften the surface and enhance dye adhesion. Apply the adhesion promoter according to the manufacturer's instructions, usually as a light coat, and allow it to flash for the recommended amount of time before proceeding.
Testing Plastic Type (Optional)
If you are unsure about the type of plastic you are working with, you can perform a simple test. Place a drop of acetone on the back of the plastic and rub it with your finger. If the plastic smears and melts, it is likely a type of plastic that requires the use of Sand Free. If acetone has no effect, opt for Plastic Adhesion Promoter or XXX Adhesion Promoter.
Warming the Environment
Before proceeding with the dyeing process, ensure that the environment is fairly warm. This helps with the adhesion and application of the dye. If necessary, use a heat gun to slowly warm the panels you will be dyeing. Alternatively, work in a warm garage or workshop to maintain a stable temperature during the process.
By following these steps, you will effectively prepare the plastic car parts for the dyeing process, ensuring a more durable and aesthetically pleasing outcome. Remember to wear the appropriate protective gear, including gloves and eye protection, during the prepping and dyeing process.

Applying adhesion promoters
To ensure that the dye adheres to the plastic surface and does not chip off easily, it is essential to apply an adhesion promoter before spraying the dye. Adhesion promoters, such as SEM Sand Free or Dupli-Color Plastic Adhesion Promoter, soften the surface and improve the adhesion of the dye to the plastic.
Before applying the adhesion promoter, it is crucial to clean the plastic surface thoroughly. Start by removing any loose paint, dirt, rust, grease, or wax from the surface using a grease and wax remover or a specialised cleaner like SEM Plastic Prep or Dupli-Color Multipurpose Foaming Prep Cleaner. This step ensures that the surface is free of any contaminants that may interfere with the adhesion process.
Once the surface is clean and dry, you can apply the adhesion promoter. Hold the can of the adhesion promoter 8-10 inches from the surface and spray in an even, sweeping motion. Apply 2-3 light coats of the adhesion promoter, allowing 3 minutes between each coat. This allows for adequate coverage and promotes better adhesion.
After applying the adhesion promoter, it is important to allow sufficient time for it to flash or cure before proceeding with the next step. For Dupli-Color Plastic Adhesion Promoter, the topcoat should be applied within 10 minutes of the last adhesion promoter coat. Following this timeframe ensures optimal adhesion between the adhesion promoter and the subsequent coating.
When working with plastics such as ABS, PVC, or similar materials, a specific technique should be followed. Apply a medium wet coat of SEM Sand Free as the adhesion promoter. While it is still wet, apply a light coat of SEM Color Coat. As the Sand Free evaporates, the Color Coat is drawn into the surface, resulting in excellent adhesion.
By following these steps and applying an adhesion promoter, you can ensure that the dye adheres properly to the plastic car parts, creating a durable and long-lasting finish.

Using SEM Color Coat
SEM Color Coat is a specialty flexible coating formulated to restore or change the colour of vinyl surfaces, flexible and rigid plastics, carpets, and velour. It is not a dye, but a fade-resistant, flexible, and permanent coating. It is available in 50 popular aerosol colours or any custom colour with the SEM Color Coat Mixing System.
To use SEM Color Coat, start by cleaning the area with SEM Soap and a grey scuff pad. Scrub thoroughly, focusing on textured or recessed areas. Rinse with water or wipe away residue with a damp cloth and let dry. Next, clean the surface with SEM Plastic & Leather Prep or Zero VOC Surface Cleaner, using a clean, lint-free towel and wiping in one direction.
To promote adhesion, apply a medium wet coat of SEM Sand Free. While it is still wet, apply a light coat of Color Coat. Avoid applying the first coat of Color Coat too heavily, as sagging may occur. As the Sand Free evaporates, the Color Coat will be drawn into the surface, resulting in excellent adhesion. Wait 15 minutes between coats and apply up to four coats.
Finally, allow the coated surface to dry. Let it bake in the sun for at least 30 minutes, and then let it sit in a garage or covered area for several days or weeks before handling the pieces.

Cleaning the plastic
Vacuum the interior
Use a vacuum to remove any debris, dirt, and dust from the car's interior. This will help prevent scratches on the plastic surfaces during the cleaning process. Remove the floor mats before vacuuming, and be extra careful around vents, knobs, and accessories as these can be easily damaged.
Dust the plastic surfaces
Use a soft, damp cloth (water only) or a soft handheld dust mop to wipe away dust from the plastic surfaces. Some people use a vinegar solution for this step, but be cautious as vinegar may leave a residue on certain types of plastic. Therefore, using water is recommended to avoid potential residue issues.
Degrease the plastic
Apply a degreaser to the plastic surfaces to remove any grease or grime. SEM offers a product called "Plastic Prep" that is specifically designed for this purpose and helps promote absorption before dying or painting. Simple Green is another product mentioned as being effective for degreasing.
Lightly sand the plastic (optional)
After degreasing, you can use light sandpaper to scuff the plastic surface, especially if you plan to paint it. This step may not be necessary for the dying process but can help prepare the surface for better paint adhesion.
Wipe with a cleaner
Use a specialized plastic cleaner, such as SEM's Soap, to thoroughly scrub the plastic surfaces. Pay close attention to textured or recessed areas. Rinse with water or wipe away residue with a damp cloth and let the surfaces dry completely.
Apply a protectant (optional)
Once the plastic is cleaned and dried, you can apply a protectant to shield the surface. Always apply sprays or chemicals to a cloth or rag first, rather than directly onto the plastic, to avoid spots and over-treated areas.
Polish the plastic (optional)
To add shine to the plastic, use a plastic polish or natural products like olive oil or boiled linseed oil. Rub the product into the plastic with a soft cloth, then use a clean, soft cloth to remove any excess.
Remember to choose the right cleaning products and methods for the specific type of plastic in your car, as some plastics may require different care. Additionally, if you plan to dye or paint the plastic after cleaning, ensure that the surface is free of any residue that may interfere with the adhesion of the dye or paint.
