Thanks Fluffy, for bringing up the subject, it was on my list too. About 4 years ago I did the 3M treatment on my headlights. Got them good as new, even clearer, and used the sealer too. But now I'm as foggy as I was back then. Currently,.. my lights show where I am, instead of where I'm going. I'll buff em' again, that's no problem, but I really need more. KStromberg answered my questions on HID, but I'm curious as to why you specified "low beams" instead of high? Since I had this car, high beams are all I use. Trust me,.. no chance of blinding anybody. I'm just wishing to see the darn road.
