Painting car trim can be a great way to improve the appearance of your vehicle, especially if the trim has been damaged or discoloured. While it is possible to paint chrome trim, it is not recommended as the paint may not adhere well and will likely peel off over time. However, if you are set on painting your chrome trim, there are a few things you should know. First, you will need to decide whether to use spray paint or a paint spray gun. Next, you will need to prepare the surface by cleaning it with a powerful cleaner, such as KBS Klean, to remove any dirt, grease, or grime. After the surface is clean, you will need to sand it, prime it, and then paint it. It is important to note that you may need multiple coats of paint to achieve the desired colour and finish. Finally, once the paint is dry, you will need to seal it with a clear coat to protect it.

Sanding the trim
Before you begin sanding, it is important to clean the trim to remove any dirt, grease, or other contaminants. You can use a powerful, concentrated cleaner like KBS Klean, or mineral spirits and a clean, lint-free cloth. Once the trim is clean, you can begin sanding by hand with 180-grit sandpaper. If you are working with a large piece of trim, you can use a dual-action sander with the same grit of sandpaper. Be sure to sand the trim thoroughly and create an even, rough surface.
After sanding, you will need to prime the trim. Some sources suggest using a spray can of high-quality urethane primer, like Krylon, and applying a light dusting followed by two to four heavy coats. Others recommend using a self-etching primer like Fusion SEP, which can improve adhesion. If you use a primer, be sure to let it dry sufficiently before moving on to the next step.
In some cases, you may need to wet-sand the trim between coats of primer. This can help create a smooth finish. Use 220-grit sandpaper followed by 400-grit sandpaper for this step, and be sure the primer is dry before sanding. After priming and any necessary wet-sanding, you can move on to the painting stage.

Using a primer
Painting your car's plastic chrome trim can be a great way to refresh the look of your vehicle, but it's important to follow the proper steps to ensure a durable finish. One of the most critical steps in this process is using a primer.
Before you begin priming, it's essential to prepare the surface of the trim. This involves sanding down the chrome to create a dull and flat surface. Use sandpaper with a grit of around 180 to 300 to sand the trim by hand, ensuring you cover the entire chrome area. For larger pieces, you may want to use a dual-action sander. Finish the sanding process with finer grit sandpaper, such as 400-grit or even 1000-grit for an exceptionally smooth finish. This will help remove any small scratches left by the initial sanding.
Once the surface is adequately prepared, it's time to apply the primer. Choose a high-quality urethane primer, such as Krylon, or a self-etching primer specifically designed to adhere to chrome, like Duplicolor Adhesion Promoter. Spray the primer onto the sanded surface, ensuring you follow the manufacturer's instructions for the best results. Apply two to three thin coats of primer, allowing each coat to dry completely before applying the next. This step is crucial, as it will help the paint adhere to the trim and create a long-lasting finish.
After priming, you can move on to the painting stage. Select a paint designed for automotive use and apply two to four heavy, consistent coats. Again, allow each coat to dry completely before handling or reattaching the trim to the car.

Painting the trim
There are several methods you can use to paint the trim of your car. One popular method is to use a spray paint designed specifically for car trim, such as Duplicolor Adhesion Promoter (Primer), Duplicolor High-Performance Wheel Coating (Paint Layer), or BlackTop. These products are designed to adhere well to chrome and plastic surfaces and provide a durable and long-lasting finish. Before painting, it is important to clean the surface with a product like KBS Klean or rubbing alcohol to remove any dirt, grease, or other contaminants that may affect the adhesion of the paint.
If you are using a spray paint, it is recommended to apply a light coat of primer first to improve adhesion and then apply thin coats of the paint, layering up to achieve the desired darkness. You can also use a clear coat on top of the paint for added protection and shine. Sanding the trim before painting can also help improve adhesion, but it is important to use the correct grit sandpaper and not to over-sand the surface.
Another method for painting car trim is to use a product like Plastidip, which is a removable, durable, and easy-to-apply coating that can be peeled off without damaging the underlying surface. This can be a good option if you are not looking for a permanent solution or if you want to experiment with different colours.
Some people also choose to wrap their car trim in vinyl, which can be a more precise and finished-looking option than painting. However, this method can be more difficult to execute well, and it may be necessary to pay a professional to do it.
Finally, it is important to note that painting chrome trim may not always be recommended, as the paint may not bond well and could peel off over time. It is always a good idea to consult a professional or seek advice from experienced car enthusiasts before attempting any paint job on your car.

Sealing the trim
Start by applying a couple of coats of primer sealer from a spray can. Allow each coat of the sealer to dry before moving on to the next step. Once the sealer is completely dry, you can begin the wet sanding process. Wet-sand the sealed trim with 220-grit sandpaper, followed by 400-grit sandpaper. This will help to create a smooth finish on the trim.
After sanding, you may want to consider applying a clear coat to further protect the paint. Some sources suggest using a clear coat, especially if the trim is rented or will be sold in the future, as it can be easily removed. If you choose to apply a clear coat, be sure to follow the manufacturer's instructions and allow it to dry completely before handling the trim.
It is important to note that even with proper sealing and clear coating, the paint on the chrome trim may still chip or peel over time, especially if it is hit by rocks or other debris. Additionally, some body shops may not recommend painting chrome trim due to the potential for the paint to peel off in the long run.
Overall, sealing the trim is a crucial step in the painting process, and by following the above steps, you can help ensure the durability and longevity of your paint job.

Using vinyl wrap
Vinyl wrapping is a great option for transforming the look of your car trim without the permanence and expense of a paint job. It is a DIY-friendly method that can be applied to chrome car parts such as bumpers, window trims, door handles, and grilles. The process is straightforward and can be done at a low cost, with the vinyl wrap simply applied over the existing chrome surface.
There are several benefits to using vinyl wrap over painting. Firstly, it is a budget-friendly and time-efficient option, costing between $300 and $700, depending on the size of the area covered and the labour costs in your area. Secondly, vinyl wrap is easy to apply and remove, allowing for customization and experimentation without causing damage to the original chrome surface. This means that you can always revert to the chrome finish if desired or re-wrap if the vinyl gets chipped or damaged.
There are different types of vinyl wraps available, including glossy, carbon fibre, and metallic finishes. Glossy vinyl wrap provides a smooth, shiny finish that closely resembles the original paint of the vehicle and comes in a variety of colours. Carbon fibre vinyl wrap has a textured design that mimics the look of real carbon fibre, giving your car a sporty appearance. Metallic vinyl wrap adds a touch of glamour and can be used to create interesting contrasts or a complete colour transformation.
When deciding between painting and vinyl wrapping your car trim, it is important to consider the potential challenges and benefits of each method. While painting may offer a more permanent solution, it is also more costly and time-consuming. Vinyl wrapping, on the other hand, is a quick, easy, and affordable way to transform the look of your car while protecting the original chrome finish.
