How to Repair Scratches on Car Headlight Covers?
2 Answers
You can use fine-grit sandpaper for sanding and polishing wax for polishing. Utilize a heater and alcohol as a volatilizing agent to attach specially processed materials onto the headlight surface via steam to fill in the scratches before sanding.
Recently, a shallow scratch appeared on one of my car's headlight covers from a tree branch. I tried a simple method I found online that turned out to be quite effective. First, clean the headlight cover thoroughly with a soft cloth to remove any grease or dust. Then, apply some regular toothpaste to a damp cloth and gently rub the scratched area in circular motions, like cleaning glass, for a few minutes before rinsing it off. For light scratches, this can usually make them disappear. For deeper scratches, you can buy a specialized headlight restoration paste, similar to a polishing compound, apply it, and then buff the area. Remember not to use hard objects or strong acidic cleaners to avoid damaging the plastic coating. Parking in shaded areas or using a protective cover can help prevent scratches. After the repair, just check that the headlight brightness remains normal. After doing this, my headlight's performance didn’t degrade, and I saved money on a new cover—usually costing just a few tens of yuan. If the scratch is still noticeable after trying this, it means it's deeper and requires professional repair—don’t push it, as it could affect driving safety.
