The sunroof my friend has on his celica is yellow and foggy. is the panel hollow and moisture got in? Its yellow so I thought maybe the sun stained it but glass doesnt stain from sun does it? Any body else have this problem? Also does anybody know if waxing the glass on a car will damage it overtime? Some idiots been waxing his glass as well as the rest of car.

you may want to check if there is a layer of old tint that is causing the cloudiness and discoloration

that would be my guess....old tint =/
