How to Get Scratches out Of Headlights: Sanding the Headlights
The sanding process must be approached carefully and methodically to achieve optimal results when removing scratches from your headlights.
This multi-stage process involves starting with coarser grits of sandpaper and progressing to finer grits to ensure a smooth finish. Proper technique and tools are essential for restoring your headlights to their original clarity.
Choosing the Right Sandpaper Grit
Selecting the appropriate grit of sandpaper is crucial for effective scratch removal. If the scratches are deep, begin with a coarse grit (800-1000), as this will help to remove the larger imperfections quickly.
Once the deeper scratches have been addressed, transition to finer grits (1500-3000) to achieve a smoother finish. The progression from coarser to finer grits ensures that each subsequent sanding stage refines the surface, preparing it for polishing.
Wet Sanding Process
Wet sanding is essential to prevent excess heat build-up and reduce the risk of introducing new scratches while sanding your headlights. Begin by soaking the sandpaper in water for a few minutes before use. This helps to soften the paper and make it more pliable.
Next, spray the headlight surface with water to keep it lubricated during sanding. The water acts as a lubricant, reducing friction and carrying away debris, which helps to prevent scratching.
Using circular motions, sand the headlight’s surface lightly and consistently, applying gentle pressure. Keeping the sandpaper and headlight surface wet is crucial, so spraying water as needed to maintain lubrication.
Regularly wipe away the residue with a clean microfiber cloth to check your progress. It’s essential to assess the headlight surface frequently to ensure even sanding and prevent over-sanding any particular area.
Sanding in Stages
As the scratches become less visible, switch to a finer-grit sandpaper. This progression helps to remove the sanding marks left by the previous grit and further smoothens the headlight surface.
Ensure that each sanding stage completely erases the marks from the previous grit before moving on to the next one. This methodical approach guarantees that the final surface is uniformly smooth and scratch-free.
Final Sanding
Use the finest grit sandpaper (2500-3000) for the final sanding stage to achieve an exceptionally smooth, even finish. Be thorough yet gentle to avoid creating new scratches. After completing the final sanding, clean the headlights with a microfiber cloth and let them dry completely, readying them for the polishing phase.
How to Get Scratches out Of Headlights: Polishing the Headlights
After sanding your headlights to a smooth finish, the next step is polishing. Polishing helps to restore clarity and shine to the headlight lenses, removing any remaining fine scratches and creating a brilliant, clear surface.
Applying Polishing Compound
Apply a small amount of polishing compound to the headlight surface using a microfiber cloth or a polishing pad. Work in small sections, rubbing the compound in a circular motion. This technique ensures that the entire surface is covered evenly.
The circular motion helps to effectively distribute the compound while minimizing the risk of creating new scratches. Continue to polish the headlight until you achieve a noticeably clearer and smoother finish.
Frequently check your progress and add more polishing compounds as needed to ensure that the entire headlight is treated uniformly.
Using an Electric Drill
Attaching a polishing pad to an electric drill can expedite polishing and provide more even results. Set the electric drill to a low speed to prevent overheating or damaging the headlight. With the polishing pad attached, gently buff the headlight surface, maintaining consistent pressure.
Move the drill in overlapping circles to evenly polish the headlight without concentrating heat in any one area. This method enhances efficiency and helps achieve a smoother, more consistent finish. Reapply the polishing compound as necessary to ensure full coverage and optimal clarity.
Buffing to a Shine
To achieve a high shine, continuously move the polishing pad or microfiber cloth across the headlight surface in circular motions. This consistent movement prevents any single area from overheating, which could potentially damage the headlight.
Once the polishing is complete, use a clean microfiber cloth to remove any excess compound. Inspect the headlights to identify any remaining scratches or dull spots. Repeat the polishing process on those areas to ensure a uniformly clear and bright finish.
