Painting dirt bike plastics is a challenging task due to the flexing and bending of the plastic surfaces, which often causes the paint to chip and peel. However, with the right tools and techniques, it is possible to achieve a satisfactory finish. This includes preparing the plastic surface by sanding and cleaning, using a flexible surface primer or a paint specifically designed for plastic, and applying multiple coats of paint and clear coat. Removing paint from dirt bike plastics can be done using chemical paint strippers, pressure washing, or non-abrasive tools and solutions like plastic scrapers and goo gone.

What You'll Learn
Using a pressure washer
Firstly, you should set your pressure washer to a thin stream setting, such as the red nozzle, which has enough force to strip paint from a car. Be cautious not to set the pressure too high, as this could damage the plastic. A setting of 0 degrees is recommended, which will produce a thin stream of water.
If the paint has already started to chip or lift, it will likely come off easily with the pressure washer. You can begin by targeting these areas to get an edge started, and then work your way across the surface. If the paint is particularly stubborn, you can try using a paint stripper or aircraft stripper beforehand to loosen it. However, be cautious when using chemical strippers, as they can be aggressive and may damage the finish of the plastic. An alternative to chemical strippers is to use brake fluid, which can be poured over the paint and left in the sun for a few minutes before washing.
Once you have treated the paint with either a stripper or brake fluid, you can use the pressure washer to blast the remaining paint off. This should be done with a good stream of water, and the force of the water will do the work for you. It is important to be careful not to direct the stream in one area for too long, as this could damage the plastic.

Paint stripper from an auto parts store
Using a paint stripper from an auto parts store is one way to remove paint from dirt bike plastics. However, it's important to note that not all paint strippers are created equal, and some can be too aggressive, damaging the plastic. It is recommended to opt for a paint stripper specifically designed for plastic parts, such as the one offered by PPG. These strippers can be found at any auto parts store or ordered through them.
Before using a chemical paint stripper, it is advisable to test it on a small, inconspicuous area first, such as the underside of the dirt bike plastic. This way, if the stripper causes damage, it will be less noticeable. It is also important to work in a well-ventilated area when using chemical strippers, as they can produce strong-smelling fumes.
The process of using a paint stripper is relatively straightforward. First, apply the stripper to the desired area. Allow it to sit for a few minutes—the exact time may vary depending on the product, so be sure to follow the manufacturer's instructions. Then, use a soft bristle brush or a non-marring plastic tool to help lift the paint off. Finally, wipe away the stripper and paint residue with a clean cloth.
It is worth noting that some paint strippers may not be able to remove all the paint, especially if it is particularly stubborn. In these cases, a pressure washer may be needed to finish the job. However, be cautious when using a pressure washer, as too much pressure can also damage the plastic.
After removing the paint, it is important to clean the plastic thoroughly to remove any residual stripper or paint. Use hot water and soap, and consider running the parts through a dishwasher cycle to ensure they are completely clean. Proper cleaning will help ensure that the new paint adheres properly and does not lift.

Sanding and spraying a thick coat of primer
- Set up a suitable work area: Choose a well-ventilated area that is protected from other surfaces, as spray paint tends to carry and smear. Work on a surface like old cardboard instead of sheet plastic, as paint soaks into cardboard and doesn't smear.
- Clean the plastic surface: Use mineral spirits or isopropyl/rubbing alcohol to wipe down the plastic. This cleans the surface and helps remove any sealants. Then, wash the piece with a wet rag and let it air dry.
- Sand the plastic: Use a fine-grit sanding block and gentle pressure to sand down the plastic. The goal is to remove the glossy finish and create a texture for the primer and paint to adhere to. Sand until you achieve a matte or dull finish.
- Remove sanding dust: After sanding, use a dry brush (a large paintbrush works well) to dust off the surface and remove debris. Then, wipe the surface with a damp cloth to ensure all dust is gone.
- Allow the plastic to dry completely: Before proceeding to the next step, ensure that the plastic is entirely dry.
- Spray a thick coat of primer: Select a primer specifically designed to work with plastic aerosol spray paints. Hold the can between 8 and 12 inches away from the plastic, tilted at a 45-degree angle. Spray lightly across the surface, avoiding heavy coats or multiple coats. Follow the directions on the primer can for best results.
- Allow the primer to dry: Give the primer sufficient time to dry completely before handling or proceeding to the next step. This could take several hours or even overnight.
Remember to take your time and follow the recommended safety precautions when working with chemicals and spray paint.

Using a non-marring plastic tool
If you are looking to remove paint from your dirt bike's plastics, one method is to use a non-marring plastic tool. This is a safe option to consider as it will not damage the original paint. You can use a plastic kitchen scraper, which can be more effective than using your fingernail.
First, you will need to soften the paint. One option is to use a spray paint thinner, which can be sprayed onto the paint and left to sit for around 10 minutes. You can also try using paste wax with carnauba, which will dissolve fresh spray paint. After letting the softening agent sit for a while, you can then use the plastic scraper to gently lift the paint off.
Another option is to use a product called "Goo Gone", which will not damage the plastics. Apply this to the paint and then use a soft scrub pad to scrub it. This method is recommended for when the plastic is solid underneath.
If you are looking to remove paint from the tank of your dirt bike, it may be more difficult to avoid damaging the original finish. In this case, it is recommended to use a chemical paint stripper, but be aware that this may damage the finish of the plastic. Always try it on an inconspicuous area first, such as the underside, to test whether it will damage the parts.

Spraying goo gone
Firstly, clean the surface of the dirt bike plastics before applying Goo Gone. This ensures that any dirt or debris doesn't interfere with the paint removal process and helps prevent scratches. Use a microfiber cloth or towel to gently wipe down the surface, ensuring a clean base to work with.
Once the surface is prepared, it's time to apply the Goo Gone. Spray the product generously onto the painted areas of the dirt bike plastics. Make sure to cover all the desired areas evenly to ensure consistent results. After spraying, let the Goo Gone sit and soak into the paint for a few minutes. This will allow the product to penetrate and loosen the paint's adhesion.
While waiting, it's important to note that Goo Gone is not recommended for extended exposure to the surface. Keep an eye on the product and don't let it sit for too long, as it could potentially affect the underlying plastic. The recommended duration may vary depending on the paint type and thickness, so it's always a good idea to test on a small, inconspicuous area first to gauge the necessary time.
After the Goo Gone has had sufficient time to work, use a non-marring plastic tool or a plastic kitchen scraper to gently lift and remove the paint. These tools are effective and less likely to damage the plastic surface compared to metal alternatives. Work carefully and methodically to avoid scratching the plastic. If needed, repeat the process for any stubborn areas or remaining paint residue.
Finally, once all the paint has been removed, thoroughly clean the surface with water and a mild soap solution to remove any remaining Goo Gone residue. Rinse and dry the plastics, and if desired, apply wax to restore shine and protect the surface.
