What You'll Learn
Using a heat gun
To use a heat gun effectively and safely, it is important to follow these steps:
Clean the Fender
Before applying heat, make sure the plastic fender is thoroughly cleaned and free of any dirt or contaminants. You can use a small handheld microfiber applicator for this step.
Prepare the Work Area
Keep the work area well-ventilated to dissipate any fumes released during the heating process. It is also important to protect surrounding areas from potential heat damage. Cover or remove any flammable materials nearby, and ensure that the motorcycle's painted surfaces are protected or taped off, as direct heat can damage paintwork.
Apply Heat with Caution
When using a heat gun on plastic, it is crucial to maintain a consistent and moderate heat level. Hold the heat gun four to six inches away from the surface to prevent overheating, burning, or melting the plastic. Keep the gun moving during the process to avoid concentrating heat in one area for too long.
Monitor the Process
As you apply heat, you will notice the plastic's molecular composition breaking down. The pigment will start to move towards the surface, and the surface may begin to melt slightly. This process eliminates sanding scratches and restores the colour. However, be cautious not to overheat the plastic, as it can cause permanent damage.
Allow Cooling and Inspect
Once you have applied heat evenly to the entire fender, turn off the heat gun and allow the plastic to cool naturally. After it has cooled, inspect the fender for any signs of damage or uneven heating. If necessary, reapply heat to any areas that require further treatment.

Scraping with a razor blade
Restoring faded plastic on motorcycle fenders can be a challenging task. It can be disheartening to see plastic items fade over time or under the impact of harsh sunlight. Sunlight contains harmful UV rays that damage plastic molecules, breaking their long molecular chains responsible for strength and colour.
One of the methods to restore faded plastic on motorcycle fenders is by scraping with a razor blade. Here is a detailed guide on how to do it:
First, identify the areas of the plastic fender that are oxidized and need to be scraped. The oxidation will appear as a thick, chalky substance that you can mark up with your fingernail. This oxidation needs to be removed to restore the plastic to its original condition.
Next, take a razor blade and hold it perpendicular to the surface of the plastic. Be very careful during this step to avoid adding more gouges or damage to the plastic. Gently scrape away the oxidation using the razor blade. The goal is to create small scratches on the surface, removing only the oxidation and uncovering the fresh, unoxidized plastic underneath. Be mindful not to apply too much pressure or force, as it may cause further damage to the plastic.
After scraping with the razor blade, you will notice that the fresh, unoxidized plastic starts to become visible. Once you have removed the majority of the oxidation, it is time to move on to the next step, which is sanding. Sanding will help smooth out the scratches made by the razor blade and further restore the plastic's shine.
It is important to remember that restoring faded plastic with a razor blade can be time-consuming and may not always produce perfect results. The restored plastic part will likely not exactly match the brand-new version, but it will significantly improve its appearance.
Additionally, always wear proper protective gear, such as gloves and eye protection, when working with sharp tools like razor blades.

Sanding
Start by assessing the condition of your plastic fenders. If they are heavily oxidized, covered in a white crust, or have deep scratches, you will need to begin with a more aggressive approach to remove the majority of the damage. Soak the fenders in soapy water or use a razor blade to carefully scrape away the oxidation, being cautious not to gouge the plastic. This initial step will help create a more even surface for sanding.
When sanding plastic motorcycle fenders, it is essential to use the correct type of sandpaper and technique. Start with a lower grit sandpaper, such as 400-grit, and trim it into small squares of approximately three-inch sizes. Soak these sandpaper squares in water before use to help lubricate the sanding process and prevent excessive scratching. Gently sand the surface of the fender, always stroking in the same direction. The goal is to create uniform scratches that will later be refined.
After the initial sanding with the lower grit sandpaper, progress to finer grits such as 1000, 1500, or 2000. These finer grits will help smooth out the scratches made by the previous grit and create a finer finish. Again, soak the sandpaper in water and work gently, following the same direction as the initial sanding. The more you refine the scratches, the better the final finish will be.
Once you have completed the sanding process, it is crucial to remove any remaining dust or residue from the surface of the fender. Use a clean, damp cloth to wipe down the fender, ensuring no dust particles are left behind. This step is essential to prepare the surface for the next step, which is typically buffing or polishing.
Finally, inspect the fender for any remaining deep scratches or imperfections. If necessary, use a razor blade to carefully remove any remaining scratches, holding it perpendicular to the surface and scraping lightly. This final touch will ensure that the plastic is ready for the final buffing or polishing stage, where you will transform the sanded fender into a shiny and restored masterpiece.
