Any one can tell me how to clean and maintain panorama roof? is wax on it ok?
thanks.

 

Since the panorama roof is glass it doesn't need wax. If you feel like waxing it, it should be safe, but don't wax your windows/windshield because the wax will deteriorate the rubber wiperblades/smear etc..
One thing you should consider is claybaring. Kragen auto parts sells the mothers kit which will remove any contaminants on the glass.

 

haha. definitely don't wax your windshields. it's not so much the wiper damage but the fact that you create a medium between your window and whatever light source you're dealing w/ (the sun during the day or street lights at night). The light coming in will refract off the medium and possibly blind you or at the very least distort your view of the road. With the sunroom, it's not a safety issue so i can't see why it wouldn't be ok. The only thing again is that your window would probably get a slight haze from the layer of wax. i would just clean with a glass cleaning agent and add rainx if you want the water to bead off.
