I tried Meguiar's PlastX on my wife's 1999 RX 300's headlights. They had some scratches, fogginess, and bug stains.
I used the PC 7424 with 4" foam spot pads. I taped off all surfaces that I wasn't polishing with PlastX. The first pass or two helped, but it was clear that it needed more. Since it was so easy, I did 5 passes on each headlight -- 3 with a coarser pad and 2 with a finish pad. Buffed with a microfiber towel. Tons of static now. Very happy with PlastX. I will probably give the tail lights a pass next time.
