You know on most neons the headlights look old, crappy, and real foggy, it's on the outside. I've never heard of em' peeling or anything but I got that fog off with about $30 bucks of supplies, but it's def. worth it and you can sell the leftovers to a friend, hehe. Here's the supplies: 600, 800, 1500, and 2000 grit sandpaper, 3M rubbing compound (fine cut), and some Turtle Wax plastic polish, I forgot what it was exactly called but it's in a white and green thing. You wet sand em' with the 600, then the 800, then 1500, then the 2000. After that you put the rubbing compound on, it gets all the scratches off. Then with a damp rag put on the polish. Make sure you have a steady flow of water the whole time your sanding or you'll have to do it agian.
