I've been using Plexus to clean the plastic rear window on my Boxster. It does a pretty good job of cleaning. However, since my top is down most of the time, I was starting to get a haze in the window where it folds on itself when the top is down. Plexus was not helping to remove the haze so I ordered some Renovo Plastic Window Cleaner from CMA.
I just tried it for the first time and the result is stunning, the window looks better than when I drove it off the lot the first day. All the haze is removed and the window is completely clear.
It also worked extremely well on the Lexan windbreak between the rollbars (you can kind of see it behind the plastic window).
Great product! :xyxthumbs
