A couple years back, I attended a Chicago Region PCA Concours school put on by several of our region's national concours champions (and judges). Pat, our top guru, showed how to polish a Boxster plastic window using a mixture of 3M Hand Glaze with a dab of Blue Magic polish mixed in...the results were amazing. I use this mixture, not only on my rear window (which looks new for nine years old), but also on all types of plastics around the house.

It really works!
