The headlights on my wife's 1991 5.0 LX Mustang were really bad from so many years in the Arizona Sun, so I bought one of those headlight polish kits on the Internet not expecting too much. It worked beautifully! You can see the before and after results. The lenses were returned to almost new condition. The "kit" contains a foam rubber polishing cup type wheel, and the polishing compound. There is enough to do the headlights and tail lights on at least 4 vehicles. I would recommend this to anyone who has plastic lenses that look a little faded. Bill T.
