A friend told me he found some stuff at Wal-Mart and did the lenses on his Voyager. Worked well, but took a LONG time. He said he pulled the light off and spent a whole night of TV just rubbing away. But they came out pretty darn good.
Anyway, I found this stuff called PlastX at Wal-Mart and I'm going to give it a try. Probably on the Intrepid first, since that's the worst of the two cars. In reading the bottle it says there's an 'oil' in the stuff that soaks in as well as a polishing agent.
