I use Novus #1 and #2 on it. When I bought the car the window had a clouded look and brittle feel. I used Novus #3 to basically sand the scum off, then #2 to get rid of the scratches, then #1 to polish it. The #1 seemed to provide some chemical that restored the suppleness of the window. I polish about once every 6 months.

Now it opens and closes just fine at any temp above maybe 45. The colder it is the slower I open the top, pausing about 3 times to let things settle slowly.
