I saw this product demonstrated in a YouTube car care video for cleaning the haze form clear headlights. It worked fantastic and they raved about the product. I must say after trying it IT ACTUALLY WORKS!! Cleaned my headlights back to new. Not sure how often I may need to reapply but they have been clean for a couple months now. Even if I have to reapply a month or two later the product went on effortlessly and wiped off easy. I highly recommend.
