How Long Does Headlight Restoration Fluid Last?
2 Answers
Headlight restoration fluid can last for about a month after application. Here are common methods for using headlight restoration fluid: 1. Polishing-style restoration: This is a common method, which basically involves sanding the headlight with sandpaper and then polishing it with specialized wax. This method shows obvious results, but it also has clear drawbacks—not every area can be polished, and the protective film will be worn off after polishing. 2. Fumigation-style restoration: This actually involves reapplying a protective film. Sealing tape is applied to the edges of the headlight, followed by sanding with sandpaper, and finally, the protective film is applied using professional tools.
I've used headlight restoration fluid several times, and the duration of the effect really depends on the situation. If you're a DIY enthusiast like me and usually park your car in an indoor garage, using a high-quality product with UV protection can last one and a half to two years. However, if your car is constantly exposed to the sun or frequently driven in rainy conditions, the problem may recur in less than six months. I recommend applying a protective spray after the restoration to significantly extend its lifespan. Additionally, the material of the headlight matters—older plastic tends to yellow more quickly. Overall, don't expect a permanent solution; it's best to inspect and maintain the headlights about once a year to prevent the lenses from becoming cloudy and affecting aesthetics.
