Painting your bike panels is a fun and satisfying project that can help you personalize your bike and express your style. It is also a cost-effective way to freshen up the look of your bike and make it stand out. Whether you are painting plastic fairings or body panels, the process is pretty straightforward and can be done at home with some basic supplies and preparation.
How to Paint Plastic Bike Panels
| Characteristics | Values |
|---|---|
| Preparation | Choose a spacious area with even flooring, such as a garage, and cover the space with plastic sheets to prevent paint spills. |
| Supplies | Sandpaper, primer, spray paint, gloves, respirator or air-purifying mask, long-sleeved clothes, mild detergent, plastic filler, plastic bonder, wax and grease remover, clear coat, paint thinner or industrial solvent, cardboard, paper towels, xylene paint remover or adhesive gunk remover, microfiber cloth, paintbrush, paint roller |
| Cleaning | Remove fairings and clean them with hot, soapy water or a mild detergent to eliminate dirt, oil, and residue. Rinse and allow to dry. |
| Sanding | Use 400-grit sandpaper to sand the surface of the fairings, creating a dull matte finish and smoothing over abrasions. Ensure all glossy surfaces are sanded. |
| Priming | Apply a layer of primer, specifically plastic primer, to the fairings. Allow it to dry for 3-6 hours. |
| Painting | Spray a thin layer of your base colour onto the fairings and let it dry. Add three more layers of paint, wet-sanding in between each coat. |
| Clear Coat | Once the final colour coat is dry, apply a clear coat to seal the paint. Finish-sanding and respraying the clear coat can create a glossy look. |
| Drying | Allow sufficient drying time between each step, and ensure the painted fairings are completely dry before reassembling. |
| Personalization | Experiment with unique colours, designs, and techniques to customize the appearance of your bike and reflect your personal style. |
| Maintenance | Regular painting and touch-ups help protect the panels and maintain the bike's appearance. |

What You'll Learn

Preparing the area and materials
Choose a Suitable Work Area:
Select a spacious area, preferably a garage or storage space with even flooring. Cover the surrounding walls and the floor with plastic sheets to create a paint booth. This will prevent paint from spilling onto unwanted surfaces and make cleanup easier. Secure the sheets to the walls using nails or tape to ensure they remain in place.
Prepare the Bike Panels:
Before starting, remove the fairing panels from your motorcycle that you intend to paint. It is recommended to take photographs of your bike and organize the panels from small to large to help with reassembly. Place the panels on a flat surface covered with cardboard to protect them. If there are any decals or warning stickers, make sure to remove them before proceeding.
Clean the Panels:
Thoroughly clean the panels with a mild detergent, hot soapy water, or an industrial solvent to remove dirt, oil, and residue. This step is crucial as it ensures the paint will adhere properly. Rinse the panels with water and wipe them down with a microfiber cloth to remove any dust or residue left behind. Allow the panels to dry completely before moving on to the next step.
Repair and Sanding:
Inspect the cleaned panels for any cracks or damages. If necessary, use a quality plastic filler or plastic weld to repair any cracks, ensuring the surface is smooth and flush. Once the filler is cured, sand the area with sandpaper to create a smooth base for the paint. The recommended grit for sandpaper varies, with suggestions ranging from 320-grit to 500-grit. This process will help remove the glossy finish and prepare the surface for painting.
Gather Painting Materials:
Before you begin painting, gather all the necessary materials, including primer, spray paint in your chosen colour, gloves, a respirator or air-purifying mask, long-sleeved clothes, and eye protection. Ensure you have adequate ventilation in your workspace to maintain safety while spraying paint.
By following these steps, you will have prepared the area and materials effectively, setting yourself up for a successful and smooth painting process. Remember to take your time and work in a well-ventilated area to achieve the best results.

Removing old paint
One method to remove old paint is to use a chemical paint remover, such as Xylene. Soak a paper towel in the remover, then spread it over the plastic panel. Leave it for 15-30 minutes, then check if the paint has started to come off by removing the paper towel. You should see wrinkles forming in the paint. Start rubbing the paint with the paper towel, and continue until all the paint is removed.
Alternatively, you can use a heat gun to soften the paint and then scrape it off with a flat-edged tool, such as a paint scraper or putty knife. Make sure the edges of your scraper are rounded and not sharp to avoid damaging the plastic. You can even use old cutlery, such as spoons or table knives. Avoid using razor blades, as these are more likely to cut into the plastic.
If you want to avoid using harsh chemicals, you can try using a kitchen scouring pad designed for cleaning anti-adherent coated cookware. This is less abrasive than a regular scouring pad and can be used together with a solvent to speed up the process. You can also try progressively harsher solvents, such as white spirit, acetone, cellulose thinners, and paint stripper. However, be aware that these solvents may damage the sheen of the paint.

Cleaning and repairing
To clean plastic bike panels, you can either use a product designed for cleaning dirt bikes or a simple soapy solution. Dip a sponge or soft cloth into the soapy water and rub it over the plastic in circular motions to loosen the dirt and grime. Rinse the plastic with water to remove the soap, and then dry it with a soft cloth.
If your bike plastic is scratched, you can try to buff out the scratches with a soft cloth. You can also use sandpaper to sand down the scratches and reveal a new layer of plastic underneath. Start with a coarse grit sandpaper, such as 400-grit, and then move to a finer grit, such as 800 or 1000-grit, to polish the plastic and give it a shine. If you are repairing a plastic fairing, make sure that the cracked area is level to ensure an even finish after painting.
If you want to remove paint from plastic panels, you can use a paint remover such as xylene or adhesive gunk remover. Wear rubber gloves for protection and place the plastic part on a cardboard strip. Soak a paper towel in the paint remover and spread it on the plastic part. Wait at least 15-30 minutes, and then start rubbing the paint with the paper towel to remove it.
If the plastic is deeply scratched or damaged, you may need to fill and repair it before painting. Remove any unnecessary trim or decals from the panel. Use heat to remove any factory decals, then apply a filler to the clean surface. Rub down the area with sandpaper to remove any scratches and create a smooth surface for the filler to adhere to. You can use a hairdryer or heat gun to help shape the filler and remove any large scratches.

Applying primer
Before applying primer, it is essential to clean the plastic panels thoroughly. Use a mild detergent or plastic cleaner to remove any dirt, grease, or debris from the surface. Once the panels are clean, dry them off with a microfiber cloth to ensure that all dust is removed.
When choosing a primer, select one specifically formulated for plastics and follow the manufacturer's instructions for application. You can buy aerosol primer at any paint supply store. Make sure to wear gloves, a respirator, and long-sleeved clothes that leave no skin exposed during the priming process.
To apply the primer, spray it in even strokes without stopping in a particular spot to avoid leaving patches. Ensure you spray from the recommended distance of about 6 to 10 inches away from the surface. A single coat of primer will usually suffice, but you may need to apply more than one coat for full coverage. Allow the primer to dry completely before moving on to the next step, which typically takes about 3-6 hours.

Painting and sealing
Before you start painting, make sure you set aside space in your garage or another large, spacious area with even flooring. Cover the space with plastic sheets from the ceiling to the ground to prevent paint from spilling. It's also important to wear protective clothing, such as gloves, a respirator, and long-sleeved clothes that leave no skin exposed.
First, remove the plastic panels from your motorcycle and place them on cardboard. Clean the plastic with hot, soapy water and a microfiber cloth to remove any dust, dirt, oil, or residue. Once the panels are clean and dry, sand the surface with 400-grit sandpaper to create a dull matte finish. This step is important to ensure the paint adheres properly.
Next, apply a layer of primer to the panels. The primer will help the paint stick to the plastic and provide a smooth base. You can use a spray primer or an epoxy primer, following the instructions on the packaging. Allow the primer to dry completely before moving on to the next step.
Now it's time to start painting! Spray a thin layer of your chosen base colour onto the panels, letting it dry before applying additional coats. It's recommended to add three more layers of paint, wet-sanding in between each coat with 1000-grit sandpaper to smooth the surface.
Once you're happy with the colour, add two coats of clear lacquer to seal and protect your paint job. This will give your panels a glossy, finished look. Allow the lacquer to dry completely before reassembling your motorcycle.
Remember, it's best to paint all the plastic parts on the same day, as weather differences between two days can affect how your paint dries and the final colour. Take your time, don't rush the process, and enjoy the satisfaction of a job well done!
