Motorcycle fairings, which are plastic or fibreglass shells that cover and protect a motorcycle's engine, frame, and rider from wind and debris, can become scratched, cracked, or broken due to accidents, collisions, or daily wear and tear. A broken fairing can compromise the safety and performance of the motorcycle and rider, leading to structural problems and instability, especially at high speeds. To prevent this, it is important to repair or seal broken plastic fairings. This can be done using a variety of methods and materials, including methyl ethyl ketone, ABS cement, PlastiFix, epoxy, fiberglass, and welding.

What You'll Learn
Clean the damaged area with a plastic cleaner
To seal a broken plastic fairing, you must first clean the damaged area. This step is crucial as it ensures that the repair process is effective and long-lasting. Here is a detailed guide on how to clean the damaged area with a plastic cleaner:
Firstly, choose an appropriate plastic cleaner. A Polyvance plastic cleaner is specifically designed to remove contaminants like tar, grease, or sticker adhesive without damaging the plastic surface. It is important to use a product that is suitable for plastic to avoid further complications.
Next, prepare the cleaning solution. For the Polyvance plastic cleaner, follow the instructions on the product and mix the solution accordingly. If you opt for a home remedy, a mixture of vinegar and water is a popular choice. Mix equal parts vinegar and water in a clean spray bottle and shake well to combine. You can also create a paste by combining baking soda and water. The paste should have a similar consistency to toothpaste.
Now, it's time to apply the cleaner. Using a clean cloth or sponge, wipe the plastic cleaner or vinegar solution onto the damaged area. Ensure you wipe in one direction to avoid recontaminating the surface. For stubborn grime or sticky residues, spray or apply more of the solution onto the area and scrub gently with a sponge or an old toothbrush. You can also use isopropyl alcohol on a cloth to tackle particularly sticky spots, but be sure to rinse the area with water afterward to remove any alcohol residue.
After thoroughly cleaning the damaged area, rinse the plastic with clean water to remove any remaining cleaner or grime. Smaller items can be rinsed in the sink, while larger items may require a garden hose. Finally, dry the area with a soft towel or cloth. Ensure the surface is completely dry to prevent water marks and inhibit bacterial or mould growth.
By following these steps, you will effectively clean the damaged area of your plastic fairing, preparing it for the next steps of the repair process. Remember to wear protective gloves and ensure good ventilation during the cleaning process.

Grind away plastic and paint with a rotary tool
To repair a broken plastic fairing, you can use a rotary tool to grind away plastic and paint. This method is useful when you want to recreate a missing piece of the fairing.
First, clean the damaged area. Use a plastic cleaner to remove contaminants like tar, grease, or sticker adhesive. Then, use a clean cloth or paper towel to wipe in one direction and avoid recontaminating the surface.
Next, use a rotary tool with a teardrop-shaped cutting bit to remove the paint from the area where the adhesive will be applied. Grind away some of the plastic so that the surface will be flush with the surrounding plastic after the adhesive is applied. Make sure to wear safety goggles or glasses to protect your eyes from debris.
You can use a variety of rotary tools for this purpose, such as the Eastwood Pneumatic Rotary Removal Tool, which operates at a maximum of 3500 RPM at 90 psi. This tool is designed to remove rust, paint, decals, and more. It features a wheel guard enclosure and an adjustable handle for maximum safety and accessibility.
After grinding away the excess plastic and paint, you can apply an adhesive like PlastiFix to create a strong and durable repair on the rigid plastic fairing.

Apply a chemical solvent to bind broken pieces
Repairing a broken plastic motorcycle fairing can be done by applying a chemical solvent to bind the broken pieces together. This method can also be used to repair cracks in the fairing. Before applying the solvent, clean the damaged area with soap and water, or a plastic cleaner for contaminants like tar, grease, or sticker adhesive.
Methyl Ethyl Ketone (MEK) is a widely available solvent that can be used to bind broken plastic fairings. To use this method, start by taping the broken plastic along the exterior to keep the fairing together. Then, pour the solvent into a container and dip a brush into it. Apply the solvent onto the interior of the broken plastic pieces, making sure to work it into the whole length of the crack. You can also apply it to any scratched areas. Press the pieces together and leave them to dry. Within half an hour, the plastic parts will be stuck together, although there may be a small seam where the pieces were joined.
Black ABS cement is another chemical solvent specifically designed for binding ABS plastic. This can be applied in the same way as Methyl Ethyl Ketone. There are also general-purpose plastic solvents called plastic weld or solvent cement that can be used for this purpose.
An alternative to chemical solvents is a non-solvent glue called JB Weld, which is a 2-part epoxy putty made for plastic repairs. Mix the two parts together and apply a small amount to the inside edges of the cracked pieces with a small brush, then press the pieces together.

Use a filler and sandpaper to smooth the surface
To seal a broken plastic fairing, you can use a filler and sandpaper to smooth the surface. This method can be used to repair cracks, fill gaps, and fix holes in plastic.
First, ensure that the plastic is clean and dry. If there is any paint on the area, use a rotary tool with a teardrop-shaped cutting bit to remove it. If there is any residue or contaminants like tar, grease, or sticker adhesive, use a plastic cleaner and a clean cloth or paper towel to wipe the surface.
Next, apply the filler to the damaged area. You can use a two-part automotive body filler, an epoxy filler, or a revolutionary thermoset methacrylate monomer adhesive system like PlastiFix. Mix the filler according to the manufacturer's instructions, and apply it to the damaged area until it follows the contour of the surface. Allow the filler to cure fully.
Once the filler is cured, use sandpaper to sand the filler smooth. You can use 320-grit sandpaper and sand in short back-and-forth strokes with constant pressure to remove any excess material and create a smooth surface. If necessary, use a high-speed die grinder with a cutting burr or a rotary tool to remove any remaining excess repair material.
After sanding, you may need to apply a primer or paint to match the colour of the plastic. Make sure to wear proper personal protective equipment (PPE), such as a face mask, respirator, gloves, and eye protection, when working with fillers and sandpaper.

Reinforce with fiberglass or carbon fibre
Reinforcing a broken plastic fairing with fibreglass or carbon fibre is a great way to repair cracks and strengthen the fairing. Fibreglass-reinforced plastic (FRP) is a composite material made of a plastic matrix and glass fibres. This combination results in a lightweight yet robust material with high mechanical strength, resistance to chemicals, corrosion, and UV radiation.
To repair a broken plastic fairing with fibreglass or carbon fibre, you will need to first clean the damaged area. Use a plastic cleaner to remove any contaminants such as tar, grease, or sticker adhesive. Then, use a rotary tool with a teardrop-shaped cutting bit to remove the paint from the area to be repaired. You may also need to grind away some of the plastic to ensure a flush surface after the repair.
Next, you will need to cut the fibreglass or carbon fibre sheet to the required size and shape. If using carbon fibre, you will also need to purchase a hardener and resin, unless you opt for a pre-made sheet. However, a pre-made sheet may not conform to the required shape. Before applying the fibreglass or carbon fibre, you may need to sand the area to be repaired with coarse sandpaper and clean it with a solvent.
Finally, apply the fibreglass or carbon fibre to the damaged area, following the instructions for the specific product you are using. Ensure that the epoxy or resin used with the carbon fibre bonds well with the fairing plastic. You may need to apply multiple layers of fibreglass or carbon fibre to achieve the desired thickness.
It is important to note that repairing a plastic fairing is slightly more difficult than repairing a fibreglass fairing. Additionally, the choice of matrix system and the design of the glass fibres can impact the properties and applications of the repaired fairing.
