Sanding: Use sandpaper or a dual-action sanding machine to smooth the surface, making it easier for paint to stick
Sanding is an essential step in preparing plastic motorcycle fairings for painting. It helps create a smooth and consistent surface for the paint to adhere to properly. You can use sandpaper or a dual-action sanding machine for this process.
If you opt for sandpaper, choose a fine-grit sandpaper, ideally with 400-grit or 600-grit. Wet the sandpaper and gently sand the entire surface of the fairings, creating a textured surface for the paint to grip onto. Sand evenly and consistently to avoid uneven paint application later on. Pay extra attention to the edges and corners, and use a sanding block to help identify the high and low points of the plastic surface. This will ensure a glossy finish.
For your convenience, a dual-action sanding machine can save you significant time and effort. However, if you choose to manually sand the fairings, the process will be more labour-intensive but equally effective if done correctly.
After sanding, it is crucial to remove all dust and debris from the plastic surface using a tack cloth or a microfiber cloth. This step ensures that no particles interfere with the paint quality or adhesion.
Additionally, consider using a plastic filler or putty to address any scratches, dents, or imperfections on the fairings. This will create an even smoother surface and enhance the final paint job's uniformity.

Primer: Apply a suitable primer, like Montana MTN PRO Plastic Primer, to the sanded plastic surface
Before applying a primer, it is important to prepare the plastic surface. This can be done by sanding the surface with sandpaper or a dual-action sanding machine. Sanding creates a smooth finish, making it easier for the primer and paint to adhere. It is important to sand all the edges and corners, and a second round of sanding should be done with sandpaper wrapped around a sanding block to help identify and smooth out any high and low points on the plastic surface. Once sanding is complete, remove all dust from the plastic using a tack cloth.
Now, you can apply the primer. Montana MTN PRO Plastic Primer is a suitable option for plastic surfaces and is available in a 400ml spray can. It is a transparent, colourless primer that can be used as a base coat for subsequent painting on plastic surfaces. The primer has special additives that give it strong adhesion to PP (Polypropylene) and other plastics. Before applying, shake the spray can vigorously until you hear the sound of the mixing ball. Then, spray the primer onto the previously cleaned plastic surface. To avoid clogging, turn the can upside down and spray until no more paint is released. This will also allow you to reuse the spray can.
The MTN PRO Plastic Primer has a touch dry time of 10 minutes and a total dry time of 20 minutes. It can withstand temperatures up to 100°C. After 10 minutes, you can apply another coat of primer if needed. Ensure that you remove any dust and clean the plastic surface between coats using a tack cloth or microfiber cloth.
Once the primer is dry, you can move on to the next step of painting. It is important to choose a paint that is compatible with the plastic surface and to follow the specific instructions for the paint you have chosen.

Painting: Use spray paint cans or a spray gun to apply paint. Ensure even coverage and follow instructions for drying times
Painting plastic fairings can be done using spray paint cans or a spray gun. Before painting, ensure that the plastic surface is clean and free of any dust or debris. It is recommended to use a gunk remover and a microfiber cloth to clean the surface. Additionally, sanding the plastic surface with sandpaper or a dual-action sanding machine can create a smooth finish, making it easier for the paint to adhere.
When using spray paint cans, it is important to follow the instructions on the can for proper application and drying times. Shake the can well before use and test the spray on a small, inconspicuous area to ensure that the paint is working and the desired colour. Hold the can about 10-15 inches away from the surface and spray in a steady, back-and-forth motion, overlapping each stroke slightly to ensure even coverage. Allow the first coat to dry before applying another coat of paint.
If using a spray gun, ensure that the paint is thinned correctly and strained into the paint cup. Test the spray pattern on a piece of cardboard or scrap material to ensure the gun is working properly and the spray pattern is uniform. Hold the gun about 6-8 inches away from the surface and use a similar technique as with spray paint cans, moving the gun uniformly in one direction to ensure even coverage. Allow each coat to dry before applying the next.
It is important to follow the specific instructions for the paint you are using, including drying times between coats and the total curing time after the final coat. These instructions can usually be found on the paint can or product information sheet. Applying a clear coat after the paint has dried can add a glossy finish and protect the paint job.

Clear coat: Apply two coats of clear enamel for a glossy finish and improved durability
Painting plastic fairings can be a great way to give your motorcycle a new look and improved aesthetics. The process involves sanding, applying primer, and paint, and finally, a clear coat. The clear coat is essential as it not only enhances the appearance of your motorcycle but also provides protection.
When applying a clear coat, it is crucial to choose the right type of clear coat and ensure that the underlying paint is completely dry to avoid any issues. The optimum temperature for painting is around 72°F, and it is recommended to avoid painting on hot or rainy days to prevent the clear coat from turning foggy due to excessive humidity.
Before applying the clear coat, make sure the plastic surface is clean and free of dust. Use a tack cloth or microfiber cloth to remove any dust or debris. You can also use an air blower to ensure the surface is spotless.
For a glossy finish, select a clear coat with a gloss level of more than 90 units. This will give your motorcycle a shiny and glamorous look. It is also important to consider scratch resistance, as cars are prone to scratches.
Apply the clear coat using a spray can or a spray gun. Hold the sprayer 6 to 8 inches away from the surface and spray in a long, smooth, and even pattern. Move the spray can or gun uniformly in one direction to ensure the clear coat is spread evenly. Allow the first coat to dry before applying the second coat. Two coats of clear enamel are typically sufficient to ensure a better finish.
By following these steps and allowing adequate drying time between coats, you will achieve a glossy and durable finish on your plastic fairings, enhancing the appearance and protecting your motorcycle.

Dust removal: Use a tack cloth or microfiber cloth to remove dust and clean the plastic surface before painting
Painting plastic motorcycle parts can give your bike a new look and improve its aesthetics. However, it is important to ensure that the plastic surface is clean and free of dust before painting to achieve the best results. Dust and dirt particles can settle on the plastic surface and cause an uneven or bumpy finish. Therefore, dust removal is a crucial step in the painting process.
One effective way to remove dust from plastic surfaces is to use a tack cloth. A tack cloth is a sticky, cheesecloth-like material that can adhere to and remove dust particles. It is designed to be gentle on the surface while effectively lifting away dust and debris. To use a tack cloth, gently wipe the surface of the plastic fairing with the cloth, ensuring that you cover the entire area. The tack cloth will pick up the dust, leaving a clean surface ready for painting.
Alternatively, a microfiber cloth can also be used for dust removal. Microfiber cloths are made of fine fibres that effectively trap and remove dust and grime. When using a microfiber cloth, you may need more than one, depending on the size of the plastic part. Spray a gunk remover or adhesive remover onto the plastic surface and start rubbing it with the microfiber cloth. The gunk remover will soften the paint and make it easier to remove. Continue spraying and rubbing until the entire surface is clean and free of dust.
It is important to be thorough during the dust removal process, as any remaining dust particles can cause imperfections in the final paint job. Take your time and ensure that all dust and debris are removed before proceeding to the next steps of painting your plastic fairings. A well-prepared surface will ensure a smooth and even finish, enhancing the overall appearance of your motorcycle.
By following these dust removal tips and choosing the right tools, you can effectively clean the plastic surface and create a smooth base for painting. Remember, taking the time to properly prepare the surface will make a significant difference in the final outcome of your painting project.
