Preparing your workspace and motorcycle

Choose a Suitable Workspace

Select a spacious area with even flooring, such as a garage or storage area. This space should be well-ventilated to prevent the inhalation of fumes and odours. Set up a pedestal fan to improve airflow and ensure additional lighting to enhance visibility during the painting process.

Prepare the Workspace

Cover the walls of your workspace with plastic sheets or other material sheets. Secure the sheets with nails and tape to prevent them from piling over each other. This will create a paint booth, providing a clean and safe environment for your work.

Prepare the Motorcycle

Place your motorcycle on a platform at a convenient angle. Remove the fairings safely using an application tool, and store the bolts in marked plastic bags. Move the motorcycle outside the painting area to protect other parts from paint stains. Thoroughly clean the fairings with a mild detergent or a mixture of hot water and dish soap to remove any dirt, oil, residue, grease, or grime. This step ensures that the paint adheres properly to the surface.

Inspect and Repair

Inspect the cleaned fairing parts for any cracks or damages. Use a quality plastic filler or plastic weld to repair any cracks, ensuring the surface is flush and smooth. Sand the repaired areas with 320 or 600-grit sandpaper, applying moderate pressure in circular motions to achieve an even finish. Remove any residual sand particles and use body fillers to smooth out bumps.

By following these steps, you will have a well-prepared workspace and motorcycle, ready for the painting process. Remember, proper preparation is key to achieving a professional and long-lasting finish.

Removing old paint and cleaning the fairings

Removing old paint from motorcycle fairings can be done in several ways. One option is to use sandpaper, starting with a higher grit and working your way down. For example, you could start with 320-grit or 600-grit sandpaper and sand in circular motions, applying moderate pressure. Then, you can move down to 400-grit and finally 80-120 grit for more precise removal around cracks. This process can be time-consuming and labour-intensive, so it is recommended to take breaks as needed. An alternative to manual sanding is to use a dual-action (DA) sander with 80-grit sandpaper, although this method may risk damaging the plastic.

Another option for removing paint is to use chemical paint removers. One product mentioned is Aircraft Paint Remover for Flexible Plastic, which effectively removes paint but may also strip it down to the bare plastic. A less aggressive option is to use paste wax with carnauba, which can dissolve fresh spray paint. Goo Gone is another product that can be applied and then scrubbed with a soft scrub pad or plastic kitchen scraper. Mineral spirits are also mentioned as an effective but toxic method of paint removal.

Once the old paint has been removed, the fairings should be thoroughly cleaned to ensure the paint adheres properly. This can be done by rinsing or wiping down the fairings with hot, soapy water and a microfiber cloth to remove any dust or dirt. It is important to allow the fairings to dry completely before proceeding with the next steps of priming and painting.

Sanding the fairings

Firstly, remove the fairings from the motorcycle by unscrewing the bolts and placing them in an open workspace. This will make it easier to work on the fairings without damaging the rest of the bike. Cover the motorcycle with a tarp to protect it from dust and debris.

Before you start sanding, it is crucial to clean the fairings thoroughly. Use a mild detergent, hot soapy water, or an alcohol-based cleaner to remove all traces of dirt, oil, and residue. This step ensures that the sanding process is effective and that the paint will adhere properly later on.

Now, you can begin the sanding process. Start by using sandpaper with a grit of around 300-600 to sand the surface of the fairings. Sand in circular motions, applying moderate pressure, until you have removed any old paint, clear coat, or scratches. You can use a dual-action sander for more efficient and even sanding. If you are working with bare plastic, be careful not to sand all the way through to the plastic itself, as this can affect the adhesion of the paint.

Once you have finished sanding, use a microfiber cloth or towel to wipe down the fairings and remove any residual dust. Rinse the fairings with water to ensure that all the dust is removed. Allow the fairings to dry completely before moving on to the next step.

After sanding, you may need to apply a plastic filler to any noticeable bumps or rough textures. This will create an even surface for the primer and paint to adhere to. Once the filler is dry, you may need to sand it again, following the same process as before.

Finally, inspect the sanded fairings for any cracks or damages. Use a quality plastic weld to repair any cracks and ensure that the surface is flush and consistent. This step is crucial in ensuring that your final paint job is smooth and even.

Remember to take breaks during the sanding process, as it can be time-consuming and tiring. Always wear protective gear, such as a mask and goggles, to safeguard against any dust or debris.

Applying primer

Painting motorcycle fairings can be a great way to add some style to your bike. The process is pretty easy, but it is important to take the time and energy to ensure a consistent and smooth finish.

Firstly, you need to prepare your work area. It is best to work in a spacious area with good lighting and even flooring. Cover the walls with plastic sheets and secure them with nails and tape. Set up a pedestal fan to blow away fumes and ensure there is plenty of ventilation.

Next, remove the fairings from the motorcycle and place them in an open workspace. Cover the rest of the motorcycle with a tarp. Clean the fairings with hot, soapy water to remove any dirt, oil, and residue. This step is crucial as it ensures the primer and paint will adhere properly.

Now, you are ready to begin sanding. Use 400-grit sandpaper to sand the surface of the fairings in a circular motion, applying moderate pressure. This step is important to ensure a smooth finish. Once you have finished sanding, rinse off the fairings and wipe them down with a microfiber cloth to remove any dust. Allow the fairings to dry completely.

Now, you can begin applying the primer. Be sure to use a plastic primer specifically designed for fairings. You can buy aerosol primer at any paint supply store. Mix the primer with the correct proportion of hardener and pour it into a spray gun. Start spraying the primer onto the fairings in even strokes, ensuring a smooth and consistent layer without any patches. Apply two coats of primer, allowing each coat to dry completely before applying the next.

After the primer has dried, you can begin sanding it with 2000-grit sandpaper using the wet-and-dry method. This will help to create a perfectly smooth and shiny texture. Be sure to remove any excess water and plastic particles after sanding.
