The fast-brite is junk!!! i tried it when it first came out. Needless to say; I would have been better off giving my money away to my favorite charity. Sanding the lens is the ultimate repair. Of course, you need to put some type of protectant on them afterwards. Hopefully something that has UV protection. Or just get the headlight covers. I know that Luminex has the clear protective covers for around $45. Good luck with your lights!
