I've always let my headlights get too far where I've had to use wet sandpaper of various grades, 1500, 2000, 3000, to get them clear. Last week after using the 2000, I couldn't find my 3000 sandpaper, I used Meguiars #18 plastic polish, used on convertible windows and such, on the headlights using my cheapee $50 buffer. Wow, I was shocked how well it worked. Cleared them right up. That got me thinking. Instead of using fine wet sandpaper, how would using rubbing and or polishing compound on the headlights followed with the Meguiars Plastic Polish? The Turtle Wax rubbing and polishing compound I have says clear coat safe.
