Removing paint from plastic tail lights can be done in several ways. One option is to use a solvent such as Goof Off, which can be purchased for a low price at Walmart, or Klean-Strip, which is a stronger alternative. Another option is to use sandpaper, either by hand or with a machine, to sand down the paint. This method is more labour-intensive but can be effective in removing paint without damaging the plastic. When using sandpaper, it is recommended to start with a lower grit paper and progress to a higher grit, such as 1500 to 3000, for a smooth finish. It is also important to keep the tail lights wet during the process and to polish the lights after the paint has been removed.

What You'll Learn
Wet sanding with fine-grade sandpaper
Wet sanding is an effective way to remove paint from plastic tail lights. It is a messy and time-consuming process, but it yields good results. Before you begin, ensure you have the right tools, including fine-grade sandpaper, a soft cloth, water, and vinegar.
First, clean the surface of the tail light with a mixture of water and vinegar, using a soft cloth. Next, soak the fine-grade sandpaper in water for about 20 minutes. The sandpaper grit will depend on the cloudiness of your tail lights. For heavily clouded lights, start with a lower grit, such as 400 or 600, and then move up to 1000 or 1500. For lightly clouded lights, you can start with a higher grit, such as 1000 or 1500, and then move up to 2000 or 3000.
When sanding, use a cross-hatching technique, making diagonal passes and alternating directions. This will help remove scratches and improve the clarity of the lens. Work evenly across the surface, applying only light pressure, and allowing the sandpaper to glide over the surface. Rinse the area and sandpaper as needed, and keep the surface well-lubricated.
Once you have finished wet sanding, the tail lights will likely appear cloudy but will look clear when wet. At this stage, you can wash the tail light to remove any remaining sandpaper or loose paint. Finally, apply wax to the tail light and allow it to dry. You can then use a buffer for a smooth, polished finish.

Using paint thinner
Removing paint from plastic tail lights can be a tricky process, as some methods may damage the plastic. One option is to use a paint thinner, but it's important to exercise caution as thinner can melt some types of plastic.
If you decide to use a paint thinner, the first step is to test it on a small, inconspicuous area of the tail light to ensure it doesn't damage the plastic. Put a very small amount of thinner on a rag and apply it to a small section of the light. If the test area looks good after drying, you can proceed with the next steps.
Before you begin, gather your materials. You'll need safety gear, including gloves and eye protection, as well as a well-ventilated workspace. You'll also need rags or paper towels, soap, and water. It's recommended to have a headlight restoration kit on hand, in case you need to buff out any haze or cloudiness that the thinner may cause.
Now, you can start the paint removal process. Soak a rag or paper towel with paint thinner and apply it to the tail light, rubbing gently. You may need to do this multiple times, depending on how much paint is on the light. Be careful not to get the thinner on any other parts of your vehicle, as it can damage paint, clear coat, and some plastics.
Once you've removed most of the paint, use paper towels to scrub away any remaining paint. Pay attention to the edges and corners of the tail light, as paint can build up in these areas. Finally, wash the tail light with soap and water to remove any residual thinner and paint.

Goof Off
Start by preparing the surface. Ensure that the tail lights are clean and free of any dirt or debris. It is recommended to use shop towels or paper towels to wipe down the surface and remove any residue.
Next, apply Goof Off to the surface. Carefully read and follow the instructions on the product label for proper usage. Allow the product to sit for the recommended amount of time, which may vary depending on the paint thickness and type.
After applying Goof Off, use a rag or paper towel to rub the surface gently. This will help to remove the paint that has been loosened by the product. Be cautious and gentle during this step to avoid damaging the plastic.
Once the paint has been removed, it is important to clean the surface thoroughly. Use a different set of towels or a soft cloth to remove any remaining Goof Off residue. Ensure that the surface is completely dry before moving on to the next step.
Finally, polish the tail lights to restore their original shine. You can use a polishing compound or buffing pad to achieve the desired finish. This step may require some elbow grease, but it will help improve the overall appearance of the tail lights.
It is important to note that Goof Off is a chemical product, and proper ventilation is crucial during its application and removal. Always wear protective gear, such as gloves and eye protection, when working with paint removal products. Additionally, be cautious when using Goof Off on plastic surfaces, as it can damage certain types of plastics. Testing on a small, inconspicuous area first is recommended to ensure the product's compatibility with the plastic tail lights.

Non-acetone nail polish remover
To use non-acetone nail polish remover, start by soaking a shop towel or cotton ball with the remover. Then, gently rub it onto the tail light. You may need to apply a little bit of pressure and work the remover into the paint. Let it sit for a few minutes to allow the paint to loosen. Finally, use a clean cloth or paper towel to wipe away the paint. You may need to repeat this process a few times to remove all the paint.
After removing the paint, it is important to wash the tail light to remove any residue. Use soap and water, and a scrub brush to gently loosen any remaining paint. Rinse the tail light thoroughly and dry it completely.
Once the tail light is clean and dry, you may notice some cloudiness or haze. This is normal and can be removed by buffing the lens with a plastic polish or rubbing compound specifically made for automotive use. You can also use a product like Meguire's PlastX, which is a fine rubbing compound made for headlights and tail lights. If you don't have access to a buffer, you can also polish the lens by hand.
As non-acetone nail polish remover may not be as effective as other methods, you may need to repeat the process multiple times to completely remove the paint. It is always a good idea to test it on a small area first to ensure it does not damage the surface of the tail light.

Buffing and polishing
Sanding:
Before buffing, it is essential to sand the surface to remove the paint. Start by removing the tail lights from your vehicle. Use fine-grit sandpaper, preferably 1500 to 2000-grit sandpaper, and constantly spray water on the tail lights while sanding. You can also soak the sandpaper in water for about 20 minutes before use to get the best results. Sand until the surface feels smooth and the paint is mostly removed. This process will leave the tail lights cloudy, but they will appear clear when wet, which is normal.
Washing:
After sanding, wash the tail lights with soap and water to remove any remaining paint, sandpaper particles, and plastic residue. Ensure you thoroughly clean the tail lights to avoid scratching during the buffing process.
Buffing:
The buffing process will smooth out the surface of the tail lights and remove any remaining paint or sanding marks. You will need a buffing wheel, a plastic polishing compound, and a tool to mount the buffing wheel, such as a drill or a bench grinder. Mount the buffing wheel securely, apply the polishing compound sparingly, and ensure you are working in a well-lit area.
When buffing, take your time and be cautious of heat build-up, which can occur quickly. Apply medium pressure and let the buffing compound do the work. Wear safety gear, including safety glasses, and avoid loose clothing. You may need to go over the surface several times to achieve the desired results.
Polishing:
After buffing, you can polish the tail lights to restore their original glossy finish. Choose a polish suitable for plastic surfaces, such as PlastX, and apply it using a microfiber pad. You can also use a polish designed for headlights, such as Griots PC or Menzerna SF3500. If necessary, you can use a compound like Griots FCC or Menzerna HC400 for more effective results.
Protection:
Finally, consider applying a sealant or coating to protect the tail lights from re-oxidation. You can use a product specifically designed for this purpose, such as a clear vinyl sealant or a sealer used on paint. Regular maintenance will help prevent oxidation and keep your tail lights looking their best.
