How to Repair a Worn Headlight Cover?
2 Answers
The headlight cover is made of plastic and is generally difficult to repair. You can try applying wax, but if that doesn't work, it's best to replace the entire headlight cover. After replacement, it's advisable to apply a protective film to the new cover for added protection. Below is some relevant information: 1. Glass Cover: Authentic vehicle headlight and taillight covers are made from high-grade polycarbonate (also known as PC, the same material used for resin eyeglass lenses) through injection molding. Polycarbonate is known for its high hardness, strength, toughness, UV resistance, and excellent light transmission. Therefore, genuine covers maintain their color and clarity even after prolonged use. 2. Car Headlights: Car headlights, also referred to as front headlamps or LED daytime running lights, serve as the 'eyes' of the vehicle. They not only contribute to the owner's external image but are also crucial for safe driving at night or in poor weather conditions. The use and maintenance of headlights should not be overlooked.
When I DIY repaired the worn-out headlight cover, I first thoroughly cleaned the surface dirt with warm water and detergent. Then I used sandpaper starting with coarse 800-grit for wet sanding, gradually switching to 2000-grit fine sanding to ensure smoothness. Next, I polished it to transparency using a polishing machine with professional polishing compound, and finally applied a layer of UV protective coating to prevent sun damage and future wear. The whole process took about an hour, and the tools can be cheaply purchased as a set online. Regular maintenance like this can extend the headlight cover's lifespan by several years while maintaining lighting brightness for safety. Remember to wear gloves during sanding to protect your hands, and avoid dry sanding to prevent new scratches.
