Painting dirt bike plastics can be a challenging task due to the flexibility of the plastic parts, which makes them prone to scratching and chipping. However, with proper preparation and the right materials, it is possible to achieve a professional-looking finish. The process typically involves sanding, cleaning, priming, painting, and applying a clear coat to protect the paint job. Some riders choose to apply decals on top of the paint for added protection against scratches and scuffs. The cost of painting dirt bike plastics can vary, with professional services charging several hundred dollars, while DIY methods can be more affordable but may require more time and effort.

What You'll Learn
Sanding and priming dirt bike plastics before painting
When it comes to painting dirt bike plastics, preparation is key. Before you begin the painting process, it's important to thoroughly clean and sand the plastic surfaces. This will ensure that the paint adheres properly and creates a smooth and even finish.
To start, use a cloth and water to scrub the dirt bike plastics. Once the surfaces are clean, you can begin the sanding process. It's recommended to use 400-grit sandpaper and sand the plastic in a circular motion. Be careful not to sand too hard, as this could damage the plastic. You can also slightly dampen the sandpaper to prevent sanding particles from scratching the plastic. After sanding, use a damp cloth to wipe away any dust and let the plastics dry completely.
Once the cleaning and sanding are complete, it's time to prime the plastics. Priming is a crucial step that should not be overlooked. The primer acts as a base coat, helping the paint adhere better and creating a smooth surface. It's recommended to use a plastic primer specifically formulated for this purpose. Apply the primer liberally to all the areas you want to paint, following the manufacturer's instructions. Allow the primer to dry completely before moving on to the next step.
For added protection and a smoother finish, consider applying a thin layer of base coat over the primer. This will provide a uniform colour and finish for your final paint colour. Again, allow the base coat to dry completely before proceeding.
Now, you can finally begin the painting process. Choose a high-quality paint designed specifically for use on plastics, such as acrylic or enamel. Spray painting is a commonly used technique for painting dirt bike plastics, as it provides an efficient and even finish. However, you can also use brush painting for a more controlled and precise application. Regardless of the technique you choose, be sure to apply light and even coats of paint, allowing each coat to dry completely before applying the next. For optimal results, two to three coats of paint are usually recommended.

Painting dirt bike plastics for a photoshoot vs. a riding season
Painting dirt bike plastics can be a great way to refresh the look of your bike, whether it's for a photoshoot or for the riding season ahead. There are a few things to consider when deciding on the best approach for painting your dirt bike plastics.
If you're preparing for a photoshoot, the main priority is often achieving a flawless and consistent finish that will look great in front of the camera. To achieve this, it's important to start with a thorough cleaning of the plastic surfaces to ensure that the paint adheres properly. Sanding is also a crucial step in creating a smooth base for the paint. Wet sanding with 400-grit sandpaper can help achieve the desired smoothness. It is recommended to perform two rounds of sanding and painting to get a better finish. After sanding, a primer should be applied, with some recommending a metal primer, such as Krylon, for a smooth and shiny finish. It's important to sand the primer to ensure a smooth surface before applying the paint. When it comes to the paint itself, a spray paint designed for plastic, such as Krylon or a product from Orchards Supply Hardware (OSH), can be a good choice. It is important to follow the manufacturer's instructions and apply multiple thin coats rather than a single thick coat.
For a riding season, the focus may be more on durability and long-lasting results. While the steps mentioned above, such as cleaning, sanding, priming, and using spray paint designed for plastic, still apply, there are a few additional considerations. Firstly, it's worth investing in a flex agent or plastic primer as a base coat. This will help the paint job withstand the rigors of riding. Additionally, a clear coat can be applied on top of the paint to provide extra protection and a glossy finish. It's important to keep in mind that a full paint job, including all the necessary materials, can cost around $150 or more, depending on the chosen paint.
In both scenarios, it's important to plan and test your painting process. Testing on a small, inconspicuous area of the bike or on a spare part can help you perfect your technique and ensure the desired results. Additionally, it's worth noting that painting dirt bike plastics is a highly customizable process, and you can choose to add custom graphics or unique color combinations to make your bike stand out.
Whether you're preparing for a photoshoot or the riding season, painting your dirt bike plastics can be a rewarding project that gives your bike a fresh and personalized look. By following the steps outlined above and considering the specific requirements of your situation, you can achieve a high-quality finish that suits your needs.

Using decals and stickers on painted dirt bike plastics
Applying decals and stickers to painted dirt bike plastics is a precise task that requires a steady hand and patience. The first step is to ensure the plastic surface is absolutely clean. If you are applying a decal to old plastic, you must remove the old decal and clean off any residual glue, dirt, or debris. A brake cleaner can be used for this step. For new plastic, it is important to remove all plasticizers or mould release agents from the surface. A solvent or brake cleaner is required to effectively clean new plastic – soap and alcohol will not be sufficient.
Once the plastic surface is clean, you can begin the process of applying the decal. It is recommended to perform a few dry runs to understand how the decal will line up and which edges and holes match up. Some people prefer to take the plastics off the bike before applying the decal, while others find it easier to apply the decal while the plastic is still on the bike to prevent any movement during the process.
When you are ready to apply the decal, use a mix of Windex and water, or a water and baby shampoo mix, to wet the plastic surface. Alternatively, a mix of soap and water can be sprayed onto the plastic. This will prevent the decal from sticking immediately, giving you some time to manoeuvre it into place. Start by lining up the ends of the decal, placing it down across the centre, and then use a squeegee to smooth it out from the centre outward, removing any bubbles.
A hair dryer or heat gun can be used to heat up the decal as you apply it, making it more pliable and easier to work with. However, be cautious not to overheat the vinyl, as it can melt or deform if it gets too hot. Once the decal is in place, use a low heat setting and a squeegee to work out any remaining bubbles and smooth the edges.

The cost of painting dirt bike plastics
For a short-term solution, such as for a single race, a simple spray paint from a hardware store can be used. This is a low-cost option, with some people reporting spending less than $10 for a basic spray paint job. However, this method may not produce long-lasting results and may require additional materials such as sandpaper and cleaning products, which could increase the cost to around $150.
For a more professional and durable finish, the cost can be significantly higher. One person reported being quoted around $600 for a professional paint job on their dirt bike plastics. This option may be suitable for those seeking a high-quality, long-lasting finish or those looking to change the colour of their bike permanently.
It is important to note that the type of plastic used on different parts of the dirt bike may also affect the cost. For example, tanks are made of a different kind of plastic, and special considerations may need to be made for the paint to adhere properly, which could increase the cost.
Additionally, the design and colour of the paint job can also impact the price. More complex designs, multiple colours, or custom graphics will likely increase the cost of painting dirt bike plastics, as they may require more materials, labour, and expertise.

Frequently asked questions
Painting dirt bike plastics can be a challenge due to the constant flexing and bending of the plastic, which can cause chipping and cracking. To achieve a professional finish, you will need to prepare the surface by sanding and cleaning the plastic, applying a suitable primer, and then painting and clear coating. Some recommend using a bath of "RIT" fabric dye to colour the plastics, but this will only work if you are dying them a darker colour.
It is important to use a paint that is specifically designed for use on plastic. Spray paint, for example, will not damage the plastic, but it will chip and peel very easily. Orchards Supply Hardware (OSH) sells spray paint for plastic that seems to work well and is as tough as the plastic itself. You can also use a paint designed for PET plastic, such as Rust Oleum.
Yes, priming is an important step in preparing the surface of the plastic for painting. There are a few different primers that can be used, such as a flex agent/plastic primer or a metal primer. It is also recommended to use an adhesion promoter on the plastics before priming to help the paint adhere better.
To make the paint stick better, you can try scuffing the surface with sandpaper before painting to create a rougher surface for the paint to adhere to. You should also make sure to clean the surface with a degreaser to remove any dirt or grease. Applying a clear coat over the paint can also help protect it and make it last longer.
