I went over mine the other week with Maguiar's PlastiX or whatever it's called. Helped some, but not all that much. More like a good cleaning than a refinishing. I'd like to try Crystal View. Not at Wal-Marts around here, though, either in Ontario or Northern NY (I'm right on the border). I'll have to check it at Advance, but the one we've got here in Ogdensburg, NY pretty much sucks. They don't carry much of anything.
