Removing dried spray paint from tail lights
Prepare the Necessary Materials
Before you begin, gather the required supplies. You will need a bucket of water, a hose or damp cloths, and either a commercial paint remover or alternative solutions like lacquer thinner, acetone, or nail polish remover. It is important to test these products on a small area first to ensure they do not damage the plastic. Additionally, you will need sandpaper, preferably 1500/2000 grit wet sandpaper, and a water sprayer or hose for wet sanding.
Act Quickly to Prevent Drying
If you notice spray paint on your tail lights, it is best to act immediately. Use a damp cloth or hose to wipe away the paint before it dries. This will be much easier than removing dried paint.
Apply a Suitable Paint Remover
If the paint has already dried, start by applying a small amount of your chosen paint remover to the affected area. Allow it to sit for a few minutes to give it time to dissolve the paint. Then, use a cloth to wipe away the dissolved paint. You can also try using denatured alcohol, which will take some time to weaken the paint before it can be wiped off.
Wet Sanding for a Smooth Finish
Once you have removed the majority of the paint, it's time to wet sand the tail lights. Soak your sandpaper in water for about 20 minutes before use. Constantly spray water on the tail lights during the sanding process to ensure a smooth and even finish. Sand until you feel the sandpaper moving smoothly across the surface.
Final Steps: Buffing and Polishing
After wet sanding, the tail lights may appear cloudy, but they should look clear if sprayed with water. At this point, you can wash the tail lights to remove any remaining paint or sandpaper particles. As an optional step, apply wax to the tail lights and let it dry for a few minutes. Finally, buff and polish the lights by hand or with a buffer if you have one. You can also use a clear vinyl sealant to protect them.
Remember, always work in a well-ventilated area and wear appropriate protective gear when handling chemicals.

Wet sanding
Preparation:
Before you begin, it is important to gather the necessary materials and prepare the surface. Ensure you have sandpaper with grits ranging from 800 to 2000. Soak the sandpaper in water for about 20 minutes to achieve the best results. Start by cleaning the tail lights with shop towels and a non-acetone solvent to remove any dirt or grease. It is crucial to protect the surrounding areas, especially the grey plastic parts, as they are vulnerable to thinner and can melt.
- Start Sanding: Using the soaked sandpaper, begin sanding the tail lights gently. Start with a lower grit sandpaper, such as 800, and work your way up to finer grits like 1000 and 2000. Sand until you notice that most of the paint has been removed, and the surface becomes evenly non-glossy. Remember to sand lightly to avoid damaging the clear coat and the plastic.
- Keep the Surface Wet: During the sanding process, constantly spray water on the tail lights to keep the surface wet. This will prevent the sandpaper from sticking to the surface and help achieve a smoother finish.
- Check for Remaining Paint: Once you've sanded off most of the paint, use paper towels and thinner to scrub away any remaining paint. Pay close attention to the edges, as they can be easily overlooked. Continue this process until only tiny dots of paint remain.
- Wipe and Spray: After sanding, wipe the tail lights with a soaked rug or use a water hose to remove any residual paint.
Finishing Touches:
- Wash and Dry: Wash the tail lights to remove any remaining sandpaper particles and loose paint. Allow the tail lights to dry thoroughly.
- Apply Wax: Once the tail lights are dry, apply a coat of wax and let it dry for a few minutes.
- Buffing: Use a buffer or your hands to buff the tail lights. If desired, you can use lamin-x or clear vinyl to seal and protect the surface.
- Inspect the Results: After completing the process, inspect the tail lights. If they still appear cloudy or uneven, you may need to repeat the wet sanding process until you achieve the desired clarity.

Using lacquer thinner
Lacquer thinner is a potent solvent that can be used to remove spray paint from plastic tail lights. It is important to note that not all paint thinners are the same, and lacquer thinner specifically is required for this task. While it is effective, it should be handled with caution as it is a harsh chemical that can melt some plastics.
Before using lacquer thinner, it is recommended to test it on a small area of the plastic tail light to ensure it does not cause any damage. If the test is successful, proceed by soaking a paper towel or shop towel with the thinner and applying it to the tail light. This process may require some elbow grease, especially when working on the edges and crevices.
It is important to protect the surrounding areas, as lacquer thinner can damage other components. Ensure you are working in a well-ventilated space to avoid inhaling the fumes. Additionally, consider wearing gloves and eye protection for safety.
Once the paint has been removed, it is crucial to clean the tail light thoroughly to eliminate any remaining thinner. After cleaning, inspect the tail light for any remaining paint residue. If there are still tiny dots of paint, repeat the process until the tail light is completely free of paint.
As an optional final step, consider applying a clear vinyl or lamin-x coating to seal and protect the tail light. This will help maintain its clarity and prevent future paint adhesion.

Removing paint with acetone
Acetone is a strong chemical that can be used to remove paint from plastic tail lights. It is important to note that acetone is a harsh chemical and can damage certain plastics, so it should be used with caution. Before using acetone, it is recommended to test it on a small, inconspicuous area of the plastic to ensure it does not cause any damage.
To use acetone for paint removal, start by dipping a rag or paper towel in acetone. Then, rub the rag or paper towel on the painted surface of the tail light. You may need to apply some pressure and rub vigorously to remove the paint effectively. It is important to work in a well-ventilated area when using acetone, as the fumes can be strong.
It is also crucial to protect your skin and eyes when working with acetone. Wear gloves to avoid skin irritation and protect your eyes with goggles or safety glasses. Ensure the area you are working in is free of any sparks or open flames, as acetone is highly flammable.
After removing the paint with acetone, it is important to clean the tail light with soap and water to remove any remaining residue. Once the tail light is clean and dry, you may want to apply a clear coat or sealant to protect the plastic and maintain its clarity.
While acetone can be effective in removing paint from plastic tail lights, it may not work for all types of paint. Some paints may be more resistant and require multiple applications of acetone or a combination of different methods, such as wet sanding, to completely remove the paint.

Buffing and polishing tail lights
Preparation:
Before you begin, gather the necessary supplies, which can be purchased from stores like Sears or Home Depot. You will need a buffing wheel, preferably a loose-style fluffy wheel, plastic polishing compound (specifically the blue compound from Eastwood Co.), and something to mount the buffing wheel on, such as a bench grinder or a high-RPM drill (1250+). Additionally, you'll require sandpaper, water, shop towels, paper towels, and a water sprayer or hose.
Sanding:
Start by removing the tail lights from your vehicle. If there are raised DOT numbers or letters on the lenses, use 400-grit sandpaper on a sanding block and apply water to sand them down until they are flush with the surface. This process will also help remove any blemishes or scratches on the tail lights. Remember to wet the sandpaper before use for the best results. Once you've completed the sanding, wash the lenses with soap and water to eliminate any remaining dirt or plastic particles.
Buffing and Polishing:
Now, it's time to buff and polish. Attach the buffing wheel to your chosen tool (bench grinder or drill) and apply the plastic polishing compound sparingly. You'll know you have enough compound on the wheel when it starts to change colour. When buffing, you have two choices: go slow and make a single pass over the surface, or go faster and make multiple passes. Going slow may result in more heat build-up, so exercise caution. Ensure you take your time, pay attention to what you're doing, and be mindful of heat build-up, as it can cause the plastic to melt or discolour. It is crucial to wear safety glasses and avoid loose clothing during this process.
Finishing Touches:
After buffing, you can apply a sealant or coating to protect the tail lights from oxidation. You can also use wax and allow it to dry before buffing again for an even smoother finish. Finally, consider using lamin-x/clear vinyl to seal and protect the tail lights, ensuring a nice and clean finish.
Remember, buffing and polishing tail lights is a project that requires time and patience. Rushing through the process may compromise the quality of the results. Always let the buffing compound do the work, and don't apply too much pressure.
