When I decided the headlights on my 96 marquis needed to be cleaned up, I used the sandpaper and polish trick. It did a great job, but took forever. Well, this time I decided to try Meguiers Plastix.... and the results were great!!!! I spent 6 bucks on the cleaner, and 20 minutes on the project.... my lights are crystal clear again and I still have plenty of polish for my brother's lights and more.... yay!!!
