For example, to restore the chrome on a car, you can use a spray chrome kit, or a special combination of non-aggressive cleaning products.

Vacuum metalizing: A base coat is applied to plastic, then exposed to an aluminium vapour cloud, leaving a chrome-like finish
Vacuum metalizing is a process that physically plates a metal material onto a plastic part in a vacuum chamber. It was first used in the 1930s to make reflective films for lenses. The process involves applying a base coat to the plastic, which serves as an adhesion promoter and provides a smooth surface for the metal layer to adhere well and reflect light effectively. This base coat is typically a primer that is specially formulated to promote adhesion and offer a smooth finish.
After the base coat is applied, the plastic part is placed in a vacuum chamber. A current is then transmitted to an evaporation source, typically a tungsten filament loaded with aluminium alloy. The current heats up the filament, causing the alloy to evaporate and form a vapour cloud, which bonds to the plastic components. This results in a thin, uniform coating of aluminium on the plastic surface, creating a chrome-like finish.
The vacuum metalizing process allows for an even coating without excessive buildup, and it is customizable, making it popular for restoration projects. It is also more environmentally friendly than other coating techniques, as the metal vapour is contained within the vacuum chamber and not released into the air.
To complete the process, a top coat can be applied to enhance the appearance and improve the chemical, moisture, and wear resistance of the coated part. This final coat also helps protect the thin, shiny layer from oxidization and wear.

Chrome spray paint: A cheap, DIY option, but may appear more like silver spray paint than true chrome
Chrome spray paint is a cheap and easily accessible option for restoring chrome-painted plastic. It can be purchased from local hardware stores and craft shops and is a good choice for remote-control hobbyists who want to add a chrome finish to their cars and planes.
However, it is important to note that chrome spray paint is not true chrome. It is simply a silver spray paint that may appear more like silver than chrome. The layer it adds is thin and prone to quick wear and tear, possibly fading, peeling, or flaking. The finish it provides will not match the shine and gloss of traditional chrome plating or even other chrome spray options like PChrome spray.
Additionally, the application process for chrome spray paint may not be as straightforward as other options. While traditional chrome plating requires toxic acid baths and sending parts to a specialized business, chrome spray paint can be applied on-site. However, it may require multiple coats and a clear protective top coat to achieve the desired finish and ensure longevity.
For those seeking a more durable and authentic chrome finish, other options like PChrome spray or professional chroming services are available but may come at a higher cost. These options provide a more mirror-like finish and are less likely to wear or fade over time.
Overall, while chrome spray paint is a cost-effective and readily available option for restoring chrome-painted plastic, it may not provide the desired chrome appearance and longevity compared to other chrome plating alternatives.

Chrome foil: Apply foil to a clean, dry plastic surface, burnishing with a cloth
To restore chrome-painted plastic, you can use a product like Bare-Metal Foil, which can be applied to a clean, dry plastic surface. Before applying the foil, wipe the area with a cloth dipped in soapy water to remove any oils and allow the foil to adhere better. Then, apply the foil, using tweezers or small needle-nose pliers to help you get a smooth finish. Trim any excess foil with an X-ACTO knife, being careful not to scratch the surface. Finally, burnish the foil with a cloth to create a shiny finish.
This method can be used to restore chrome finishes on various items, such as car trim, radios, and plastic toys. It is important to note that real chrome plating requires the use of toxic chromic acid, which can be dangerous and is not recommended for amateurs. Instead, products like Bare-Metal Foil provide a convincing chrome appearance without the need for electrolysis or dipping.
For car owners looking to restore chrome-plated plastic, there are a few options. Some choose to strip the old chrome and apply a new coat of chrome spray.

Chrome spray: Strip old chrome, paint gloss black, then chrome spray
Restoring chrome-painted plastic can be a challenging task, but with the right tools and techniques, it is achievable. Here is a step-by-step guide to the process of "Chrome spray: Strip old chrome, paint gloss black, then chrome spray".
Strip the Old Chrome:
Begin by removing any unwanted bends or dents using a body hammer. This step is crucial to ensure a smooth surface before proceeding with the painting process. Make sure to hammer out the dents from the interior side, placing a hard material against the exterior surface to provide support.
Next, use a media blaster or a blasting gun to strip the old chrome paint from the plastic surface. This method utilizes pressurized air and small particles to effectively remove the paint without damaging the base material.
Prepare the Surface:
Once the old chrome is removed, it is essential to prepare the surface properly to ensure that the new paint adheres well. Start by sanding the surface to create a rough texture that will allow the paint to grip. After sanding, wipe down the surface with a wax and grease remover to ensure it is clean and free of any residue.
Apply Primer:
Before painting, it is crucial to apply a primer to the sanded and cleaned surface. Use a two-part epoxy primer and apply two coats, allowing each coat to dry completely before proceeding. This primer will provide a good base for the paint to adhere to and help create a smooth and even finish.
Paint Gloss Black:
Choose a high-quality gloss black paint designed for automotive use, such as the Rust-Oleum Automotive Gloss Black Custom Chrome Spray Paint. Maintain a distance of about 6 inches between the spray gun or paint canister and the surface, and use a sweeping side-to-side motion during application. Allow each coat to dry completely before applying the next, following the specific instructions on your chosen paint product.
Chrome Spray:
After the gloss black paint has dried, it's time to apply the chrome spray. Use a specialized chrome spray paint, such as Molotow Liquid Chrome, which can be sprayed through an airbrush or purchased in a bottle. Follow the same spraying technique as with the gloss black paint, ensuring an even and consistent coat. Allow the chrome spray to dry completely before handling or adding any additional coatings.
Finally, consider adding a clear coat finish to protect the newly painted surface and add a polished appearance. You can use an automotive clear coat paint, following the same spraying techniques, to complete the restoration process.
