Painting a chrome plastic bezel can be a challenging task. While some opt for a simple approach of brushing and painting, this method often results in the paint wearing off quickly as it does not bind well to the plastic surface. To achieve a longer-lasting paint job, the chrome finish must be removed by sanding, creating a rough surface for the paint to adhere to. Additionally, using a plastic bonding paint specifically designed for this purpose is crucial. For those seeking a more realistic chrome finish, modelers' chrome foil, a thin, self-adhesive, and highly reflective material, can be applied with patience and precision. Alternatively, one may consider specialty shops that offer chrome plating services for plastic parts, ensuring a professional and durable result.

What You'll Learn
Removing the chrome finish
One method is to use an abrasive blaster, a machine that sprays fine-grain powder or tiny pellets to abrade the chrome material. Sandblasting is a type of abrasive blasting that can be used to remove chrome from plastic. However, this method can be challenging to access for some people. Another option is to use a pressure washer and scraping to remove the chrome finish. While this method may be effective, it can be a slow process.
Chemical solutions can also be used to remove chrome from plastic, but it is important to note that these solutions can be highly corrosive and may damage the plastic if not used properly. One such chemical solution is hydrochloric acid (muriatic acid), which can be purchased as a pre-mixed solution or mixed at home by combining one part hydrochloric acid with two parts water in a heavy-duty plastic bucket. The chrome-plated object is then submerged in the solution until the chrome strips off. It is important not to leave the object in the solution for longer than necessary to avoid damage. After removing the object from the solution, it should be thoroughly washed with soap and water, rinsed, and dried.
Alternatively, a strong detergent or floor cleaner can be used to remove chrome from plastic. Products such as Mr Muscle Professional Floor Cleaner or ordinary washing-up liquid can be effective in removing chrome without harming the plastic. Another option is to use an oven cleaner that contains caustic soda. The oven cleaner can be sprayed on and left overnight, and the chrome plating should be removed by morning.
For thin or weak chrome plating, a homemade abrasive can be used. This method involves mixing baking soda or a solid household cleanser with water to form a paste that can be rubbed onto the chrome with a soft cloth until it begins to come off. This method may require some elbow grease, but it is a beginner-friendly option.

Preparing the surface
Painting a chrome plastic bezel requires a lot of preparation. Firstly, it is important to protect yourself. Wear a respirator that conforms to OSHA standards to filter out any particles in your paint or primer that could lead to lung infections. Also, wear ear protection to avoid hearing damage.
Next, you need to prepare the chrome plastic bezel. Wash the chrome piece with basic soap and water and dry it thoroughly. Then, sand the entire piece with 220- to 320-grit paper, and use 120- or even 60-grit for any deeper scars, rust, or pits. Be sure to sand down any runs from the primer, as chips or flaws will be more visible once paint is applied. Spend time on this step to obtain a smooth surface.
After sanding, wipe down the piece with a clean cloth or tack rag to remove all sanding dust. Then, wipe down the piece with either lacquer thinner or wax remover. You can also use a wax and grease remover to spray down the parts.
Finally, cover your workspace and surrounding surfaces, such as trim, windows, and floors, with a drop cloth. This will protect these surfaces from any paint splatters and spills.

Choosing the right paint
Painting a chrome plastic bezel can be a challenging task, as the chrome finish is often smooth and slippery, making it difficult for paint to adhere. To ensure a successful paint job, it is crucial to select the right type of paint and prepare the surface properly.
When choosing paint for a chrome plastic bezel, it is essential to opt for a product specifically designed for plastic adhesion. Regular paint will not bind well to the chrome surface, and it may wear off quickly. Look for paints labelled as "plastic adhesion" or "plastic bonding" to ensure a strong and long-lasting finish. Some recommended products include adhesion promoter spray paint for plastic and plastic adhesion primer.
It is also important to consider the desired colour and finish. Chrome has a distinctive shiny, reflective appearance, and achieving an exact match with paint can be challenging. Many users have reported that paint products marketed as "chrome" actually appear as flat silver or silver paint, rather than a true chrome finish. If a close match to the original chrome finish is important, it may be necessary to explore specialty shops that offer chrome plating services. However, if a slight variation in colour is acceptable, a shiny silver paint or a "dull aluminum" spray paint by Krylon can be a good alternative.
Additionally, the type of paint finish should be considered. A satin or flat black paint can provide a sleek and modern appearance, while clear coats can add a glossy shine to the final product. It is also recommended to use the same brand of paint throughout the project to avoid compatibility issues and ensure a consistent finish.
In conclusion, when choosing the right paint for a chrome plastic bezel, it is crucial to select a product specifically designed for plastic adhesion and to consider the desired colour, finish, and brand compatibility. Proper surface preparation, such as sanding and priming, is also essential for a successful and long-lasting paint job.

Application techniques
Painting a chrome plastic bezel requires a lot of preparation and the right tools. The process is not as simple as just painting over the chrome finish, as the paint will not bind to the plastic and will wear off quickly.
Firstly, you need to disassemble the bezel and remove the chrome finish. This can be done by sanding it down with fine-grit sandpaper to create a rough surface for the paint to adhere to. It is important to note that this process may require the use of a heat gun to remove the bezel, especially if it is glued to the screen. Once the bezel is removed, use a clean rag dampened with a bit of thinner to wipe down the surface, removing any dust or residue.
Next, you need to choose the right paint. It is recommended to use a plastic bonding paint designed for use on plastic surfaces. If you are looking for a chrome finish, you can use an enamel chrome modelling paint in aerosol form, or try applying modellers' chrome foil, which is a thin, self-adhesive, highly reflective foil that looks like chrome. This will require a steady hand and patience.
Before painting, it is important to clean the surface with a degreaser and ensure that it is free of any dust or residue. It is also recommended to use a primer to help the paint adhere better and create a smoother finish.
When painting, use light, even coats and allow each coat to dry completely before applying the next. It may be necessary to apply multiple thin coats to achieve the desired finish.
Finally, once the paint is dry, you can reassemble the bezel and admire your handiwork!

Finishing and maintenance
When it comes to finishing and maintaining a painted chrome plastic bezel, there are several important considerations to keep in mind. Firstly, it is crucial to understand that chrome is not a paint but a finish that is baked on. Therefore, any touch-up paint is likely to look noticeably different. While it is possible to polish the chrome, one must be cautious as the heat generated can damage the plastic.
For a more durable and long-lasting solution, consider using a paint designed for plastic adhesion. Before painting, ensure that the surface is thoroughly cleaned and degreased, and lightly sanded to create a rough surface for the paint to adhere to. It is recommended to use a plastic bonding paint or a spray paint specifically formulated for plastic surfaces. Additionally, using a primer before applying the paint can enhance adhesion and improve the final result.
To achieve a chrome-like finish, there are a few options available. One method is to use a high-end, proprietary 3-step system that includes a primer, silver nitrate, and a clear coat. This combination can create a more realistic chrome appearance. Another option is to use a chrome modelling paint or enamel chrome modelling paint, which can provide a more realistic chrome effect. Additionally, modelers chrome foil, a thin, self-adhesive, and highly reflective foil, can be applied to create a chrome finish. However, this requires patience and a keen eye for detail.
For maintenance, it is important to handle the painted surface with care to prevent scratches or chipping. Regular cleaning with mild soap and water can help maintain the finish. Additionally, using a clear coat or sealant specifically designed for painted plastic surfaces can provide added protection and prolong the life of the paint job.
If the chrome-painted bezel shows signs of wear or damage, it may be necessary to strip the old paint and start the painting process again. This involves carefully removing the paint without damaging the underlying plastic surface. It is recommended to use a paint stripper or a heat gun to remove the paint effectively. Once the surface is prepared, the new paint can be applied following the same steps as mentioned earlier.
