What to Do When Headlight Coating Peels Off?
2 Answers
To address headlight issues, it is essential to regularly apply a protective coating to the headlights to prevent premature aging and the formation of cracks. When reapplying the coating, it is necessary to remove any residual film from the headlight cover and smooth the surface to ensure the effectiveness of the new coating.
Having driven for decades, I've seen headlight coating peeling quite often, usually caused by prolonged sun exposure or using harsh chemicals during cleaning that degrade the plastic. Once the coating peels, the headlights turn yellow and hazy, making night driving dangerously unclear. The solution is to first thoroughly clean the lens with mild soapy water to remove grime without leaving oil residue. Then, gently wet-sand the surface smooth with 2000-grit sandpaper, applying even pressure to avoid damaging the housing. After sanding, apply a specialized polishing compound to restore shine, followed by a UV-protective sealant spray to prevent future peeling. For daily care, park in shaded areas when possible and use pH-neutral car wash soap to preserve the coating. If DIY seems daunting or damage is severe, professional auto shops or dealerships can respray the coating with specialized equipment for longer-lasting results—costing a few hundred bucks, which is far more economical than full headlight replacement. Prevention is key; regular inspection and maintenance can spare you this hassle altogether.
