Painting chrome plastic requires a lot of preparation. The surface must be cleaned and sanded to ensure the paint adheres properly. This is because chrome reacts with oxygen to form rust, so it is important to remove any rust or clear coat that has accumulated. The next step is to apply a primer, which should then be sanded again to smooth the surface. Finally, you can apply your paint. There are several types of paint and primer to choose from, such as Krylon Fusion, self-etching primer, or a spray chrome kit.

What You'll Learn
Cleaning the surface
- Begin by washing the chrome surface with soap and water. Use a mild dish soap or automotive soap and warm water. You can use a sponge, soft cloth, or toothbrush to gently clean the surface. Rinse away any soapy residue with plain water and ensure that the surface is thoroughly cleaned.
- If there are any bends or dents on the chrome plastic, use a body hammer to gently hammer out these imperfections. It is important to do this before cleaning and painting to ensure a smooth surface.
- Once the surface is clean and dry, you can start sanding. Sanding helps to create a rough surface for the paint to adhere to. Use rough sandpaper, such as 120-grit, to sand the surface evenly and thoroughly. This step will also help remove any thin, clear rust that may have formed on the chrome.
- After sanding, wipe down the surface with a wax and grease remover or isopropyl alcohol to ensure that any residual dust, dirt, or grease is removed. Use a lint-free microfiber cloth for this step to avoid leaving any fibres on the surface.
- To further prepare the surface for painting, you can apply a primer. A self-etching primer will help the paint adhere better, and a rust-inhibiting primer can be used if necessary. Spray two to three coats of the chosen primer onto the chrome surface and allow it to dry completely.
- Finally, sand the primer using fine sandpaper (400 to 600 grit) to ensure a smooth and even finish. Be careful not to touch the chrome surface with the sandpaper, as you only want to sand the primer. Remove any dust or residue with a microfiber cloth or paper towel.
Now that the chrome plastic surface has been thoroughly cleaned and prepared, you can move on to the painting stage, following the instructions provided by your chosen paint product. Remember to work in a well-ventilated area and wear protective gear, such as a respirator, to safeguard your health during the painting process.

Sanding the surface
Clean the Surface: Before you start sanding, it is essential to clean the chrome plastic surface thoroughly. Use a damp cloth to wipe down the surface and remove any dirt, grime, or residue. This step is crucial because it ensures that you are not sanding over any foreign particles, which could create an uneven surface.
Start with the Right Sandpaper: Choose the appropriate sandpaper grit for the initial sanding. It is recommended to start with a grit between 120 and 220 to remove any clear rust, bubbles, or particles on the chrome surface. This type of sandpaper is considered "rough" and will help strip away the top layer of chrome.
Sand Evenly and Thoroughly: Apply even pressure as you sand the entire surface, including the edges. Make sure to sand in the same direction, following the grain of the chrome, to avoid creating cross-hatch patterns. Take your time and be thorough, ensuring that you remove any rust, bubbles, or imperfections on the surface.
Switch to Finer Sandpaper: Once you have evenly sanded the surface with the initial grit, it's time to refine the sanding. Switch to a finer sandpaper grit, such as 240-grit or 320-grit. This step will help remove any scratches or marks left by the previous sanding. It will also help create a smoother finish, reducing the visibility of sanding marks.
Fill and Level Deep Scratches: If there are any deep scratches, gouges, or low spots on the chrome surface after the initial sanding, fill them appropriately. You can use liquid steel, glazing compound, or a similar product to fill in these areas. Once the filler is dry, sand it level with the surrounding surface using a heavier grit sandpaper, and then progress to finer grits to smooth it out.
Wipe Down the Surface: After sanding, use a clean cloth or tack rag to wipe down the chrome surface. Remove all the sanding dust and residue to ensure that the surface is ready for the next steps, which may include applying a primer and painting.
Remember, when sanding chrome plastic, always wear appropriate personal protective equipment (PPE), including a respirator that conforms to OSHA standards. This will protect you from inhaling chrome dust, which can be harmful to your health.

Applying primer
Painting over chrome plastic can be a tricky process, and it is important to take the necessary precautions to ensure a smooth and seamless finish. Here is a step-by-step guide to applying primer to chrome plastic:
Preparing the Surface:
Before applying primer, it is crucial to prepare the chrome plastic surface. Start by washing the chrome plastic with soapy water to remove any dirt, grease, or debris. You can use a kitchen sink or a bucket to wash the surface thoroughly. Once cleaned, dry the surface with a clean cloth or towel. It is important to ensure that the surface is completely dry before moving on to the next step.
Sanding:
To create a rough surface for the primer to adhere to, you will need to sand the chrome plastic. Use sandpaper with a grit of around 80 to 150 for this initial sanding process. Sand the surface evenly, paying extra attention to any curved areas or crevices. After sanding, use a clean cloth or tack rag to wipe away any dust or residue left behind.
Choosing the Right Primer:
Not all primers are suitable for chrome plastic. It is essential to choose a primer specifically designed for plastic surfaces. Look for primers with the label "plastic adhesion promoter" or "adhesion promoter." These primers will ensure that the paint adheres properly to the chrome plastic surface. You can find these primers at auto parts stores or reputable DIY shops.
Applying the Primer:
Now it's time to apply the primer. If using a spray primer, hold the can or spray gun at least 10 inches away from the surface and continuously move it to avoid excessive paint buildup in one area. Apply light to medium coats, allowing each coat to dry before applying the next. Two to three coats of primer are usually sufficient. If you are using a brush-on primer, use a large, flat paintbrush to apply a thin layer of primer, ensuring even coverage.
Drying and Inspection:
After applying the primer, allow it to dry completely. The drying time may vary depending on the primer used, but it is generally advisable to wait at least 24 hours before proceeding. Once dry, inspect the surface for any flaws or imperfections. Run your hand over the surface slowly, feeling for any bumps or pinholes. If necessary, use glazing spot putty to fill in any imperfections and sand the area again with fine-grit sandpaper.
Safety Precautions:
Throughout the priming process, it is crucial to prioritize your safety. Wear long sleeves and trousers to protect your skin from any corrosive substances in the primer. Additionally, wear safety goggles and a respirator that conforms to OSHA standards to protect your eyes and lungs from harmful particles and vapors. Ensure the work area is well-ventilated to avoid inhaling toxic fumes.
By following these steps and taking the necessary precautions, you can effectively apply primer to chrome plastic, creating a smooth and durable base for your chosen paint. Remember to take your time, work in a well-ventilated area, and always prioritize your safety throughout the process.

Choosing a paint type
Painting chrome plastic requires a lot of surface preparation, including cleaning, sanding, and applying primer. You can also buy a proper plastic that you can paint, which may be more expensive but is a quicker option with better paint adhesion.
There are several ways to paint chrome plastic, and the type of paint you choose will depend on the look you want to achieve and the amount of effort you are willing to put in. Here are some options:
Chrome Spray Paint
Spray paint is a cheap option that can be done at home. However, it may not give a true chrome finish and may require a base coat, which can be difficult to apply evenly. Spray paints like PChrome can be applied on-site and provide a durable, highly reflective, and scuff-resistant finish. They also come in different colours, including blue, red, gold, and silver.
Chrome Film
Chrome film is a laminate with an adhesive backing that can be wrapped around curved areas or applied to flat surfaces. It is easy to tear, gouge, or scratch, and may not have the same strength and feel as true chrome. It is also prone to wrinkling, especially on curved surfaces.
Vacuum Metalizing
This method involves applying a base coat to the plastic and then exposing it to a vapour cloud made out of aluminium. The vapour cloud bonds to the plastic's surface, leaving a chrome-like shine. However, this option may be time-consuming and expensive as it usually requires sending the part off to a professional.
Chrome Plating
Chrome plating is a traditional method that involves coating the plastic in layers of nickel and copper before applying the chrome. This method usually requires sending the plastic parts to a plating company, which can be costly and time-consuming.

Finishing and buffing
Finishing
Once the chrome paint has been applied, it's important to let it dry completely. The drying time may vary depending on the paint type and environmental conditions, so always refer to the manufacturer's instructions. Impatience at this stage can compromise the integrity of your paint job.
After the paint has dried, it's time to apply a clear coat. This step is essential for two reasons. Firstly, it protects the chrome paint from the elements, such as dust and moisture, which can cause rusting and dulling over time. Secondly, it gives your project a polished and glossy appearance, enhancing the shine of the chrome.
Apply at least three coats of automotive clear-coat paint, following the instructions on the product for proper application and drying times. This step ensures a consistent and durable finish.
Buffing
Buffing is the final step in achieving a show-quality chrome finish. It enhances the shine and gloss of the surface, giving it that extra pop. Using a buffing cloth or a high-speed buffer, gently work a buffing compound into the clear coat. This process will smooth out any remaining fine scratches and imperfections, resulting in a mirror-like finish.
It's important to note that buffing requires a gentle touch and practice. Excessive buffing or using too much pressure can damage the clear coat and underlying paint, requiring you to start the process all over again.
Additionally, always wear the appropriate personal protective equipment (PPE) when buffing, as the process can generate heat and dust. This includes eye protection, a respirator, and gloves.
By following these finishing and buffing instructions, you'll be able to achieve a professional-looking chrome paint job that will turn heads and last for years to come.
