At the above link is an article (two pages) from the "Hemmings Sports & Exotic Car magazine, March 2009 issue. In order to clean and polish the headlights of the Lexan plastic covers for headlights, they follow much the same approach as has been on this forum before, however, the big difference is the use of Meguiars mag and aluminum wheel polish vs a "polishing compound". The wheel polish is apparently a bit more abrasive than most of the plastic polishes on the market.
I haven't tried it yet, but I think I will ......
