There are several ways to re-chrome plastic trim. One way is to use a chrome spray paint, which can be done at home but may not give the desired chrome finish. Another method is vacuum metalizing, where a base coat is applied to the plastic parts, followed by exposure to an aluminium vapour cloud. Chrome plating is also an option, where a company will coat the plastic part in layers of nickel and copper before applying chrome. This process can be expensive and is only suitable for rigid plastics.

What You'll Learn
Vacuum metalizing
To enhance the adhesion and protect the chrome finish, a top coat is applied over the metalized layer. This protective layer guards against scratching, marring, oxidation, and degradation from ultraviolet light. The entire process is known as Physical Vapor Deposition (PVD) and results in a bright chrome finish on the plastic substrate.
However, it is important to note that vacuum metalizing is typically applied only to rigid plastic parts. Flexible plastics may not be suitable due to the potential for stress fractures during the process. Additionally, the process can be time-consuming and expensive, as it often requires sending the parts off to a specialized company. Nevertheless, it is a commonly used technique, particularly in the manufacture of flashlight reflectors, where the chrome-like finish is desirable.

Chrome spray paint
There are also specialised chrome spray kits available, such as PChrome, that can provide a high-quality chrome finish on plastic surfaces. These kits are designed for DIY enthusiasts and professionals, offering different sizes to cater to various projects. The PChrome spray-on chrome for plastic claims to provide the same look and strength as traditional chrome plating, with a high-gleam polish and the ability to bond well to almost any surface. It offers versatility in terms of application and is available in multiple shades, including blue, red, gold, and silver.
Another method to achieve a chrome-like finish on plastic is vacuum metalizing. This process involves applying a base coat to the plastic part and then exposing it to a vapour cloud made of aluminium. The vapour bonds to the plastic's surface, resulting in a shine similar to chrome. However, this method can be time-consuming and expensive as it typically requires sending the parts off for treatment.
Additionally, some companies offer professional chrome plating services for plastic parts. This process involves coating the plastic in layers of nickel and copper before applying the chrome finish. While it can be costly, it may be preferred by those seeking a more durable and long-lasting solution.

Chrome plating
One popular method is chrome spray paint, which is a cheap and easy option for DIY enthusiasts. However, it may not produce a true chrome finish, and the base coat may show through if not carefully applied. For a more professional finish, you can send your plastic parts to a plating company, which will coat them in layers of nickel and copper before applying the chrome. This process is similar to metal chrome plating and is suitable for rigid plastics.
Another method is vacuum metalizing, commonly used for flashlight reflectors. This involves applying a base coat to the plastic parts and then exposing them to an aluminium vapour cloud. The vapour bonds to the surface, leaving behind a chrome-like shine. However, this method can be time-consuming and expensive.
If you're looking for a more unique finish, you can consider "Killer Chrome", which involves applying a clear coat over the chrome plating. However, some people have found that this can result in a less-than-desirable appearance.
Before undertaking any chrome plating project, it's important to clean the plastic surface thoroughly. This can be done using mild car wash soap mixed with warm water, gently applied with a microfiber cloth. For stubborn dirt, a soft-bristled brush or toothbrush can be used, being careful not to scratch the surface. Finally, the surface should be rinsed with clean water and dried thoroughly to prevent water spots and streaks.

Copper and nickel coating
To prepare the plastic for electroplating, several preliminary steps are necessary. Firstly, molding is required to ensure the plastic part is of the right shape and quality for effective plating. This involves converting plastic pellets into a suitable form. The plastic part must then be cleaned using a mild alkaline solution or a chromic acid solution to ensure thorough wetting prior to etching.
Once the plastic has been prepared, it is ready for the electroplating process. This typically involves setting up a plating station with a rectifier to provide a DC current, an anode (a solid piece of copper), a cathode (negatively charged electrode), a plating solution, and a plating tank or barrel. The negative lead of the rectifier is attached to the immersed substrate, while the positive lead is placed in the plating solution with the copper anode.
Copper is a popular choice for automotive parts due to its resistance to blistering. It is also used when electrical conductivity is required. Nickel, on the other hand, is often used as an initial coating to make the plastic surface conductive before further electroplating. Nickel baths provide uniform plating results and are easy to control.
The choice between copper and nickel depends on the specific application and the desired outcome. In some cases, multiple layers of different metals may be applied for added benefits, such as enhanced corrosion resistance or improved strength.

Cleaning with mild car wash soap
When cleaning your car with mild car wash soap, it is important to remember that not all soaps are created equal. Some soaps are designed to be used with specific tools, such as foam guns or cannons, while others are meant to be applied by hand. Additionally, if you plan to add a wax or ceramic coating after washing your car, consider using a regular car soap to ensure your car is thoroughly cleaned before applying additional products.
Before you begin washing, it is important to rinse all surfaces thoroughly with water to remove loose dirt and debris that could cause scratching. When using mild car wash soap, it is crucial to follow the instructions on the product and use it in conjunction with other car care products, such as wax or ceramic coatings, as intended.
When washing your car, concentrate on one section at a time, washing and rinsing each area completely before moving on to the next. This ensures that the soap does not dry on the surface and helps prevent scratching. It is also recommended to start at the top of the car and work your way down. Using a hose without a nozzle can create a sheeting action that aids in rinsing soap from the body and reduces water pooling, making it easier to dry the vehicle.
While washing your car, it is important to work the car wash solution into a lather with plenty of suds to provide lubrication on the paint surface. Rinse your sponge frequently to avoid transferring dirt back onto the car's surface.
Although automated car washes are convenient, they can be expensive and may damage your car due to the grinding of grime from other vehicles or catching on loose parts. If you choose to use an automated wash, touchless options are best to protect your car from potential harm.
