Mothers PowerBall Mini with Plastic Polish -- if they're really hazy, use the PowerMetal polish first to do a good cut.
Now you might want to carefully mask the surrounding painted areas with light painter's tape, but do a test area first to make sure the 11-year-old paint won't lift. If you're careful, you might be able to get by without masking, but expect to keep after a little bit of sling.
Here is a link to the Honda S2k sight, ( wife has a s2000) anyways this guy used Plastic 210 I'm pretty sure you can buy the stuff at your local marine shop, i guess alot of boat people use it.. he also used a buffing wheel but ended up with good results.. also look around on the finish section while your there, they have a bunch of good tips......http://www.s2ki.com/forums/index.php?showtopic=296109
I bought the powerball but ended up doing it all by hand after some testing and seeing good results......
And NO...the after picture is not a new tail light or a different car, just the right hand side as opposed to
the before picture which is obviously the left hand side!! (i used the right side for the after because the light
was better for a decent picture, which is probably why it looks whiter)
