Foggy Headlights? [View all]

My wife had a parking lot event not long ago. Broke the passenger side headlight assembly.
So, I bought a new one and installed it. (Grrr; stupid engineers)
Anyway, the new one is crystal clear but the old one looked like a bathroom window in comparison.
So, I bought one of the 3M headlight refurbishing kits.
Yep, they work!!!! Just as advertised.
I did the old headlight on her car & both on my car. Wow!
4 step process, which is basically sequential sanding (dry then wet).
Takes 6 or 7 minutes per light.
Admittedly, the driver side on her car is not as crystal clear as the new one, but darned close, with no scratches.
If you have dim headlights at night, I recommend this product highly. All you need is a cheap drill which most folks already have. And, headlights can easily be done while sitting in a lawn chair.
I figured I'd give it a shot and it worked better than I expected and was easier than I thought.
If I'd known, I'd have done it a couple years ago.
