So i was waxing my car the other day, and I was working on the roof and noticed that one side of my sunroof is lower than the molding, leaving about a 1 centimeter "ledge." The problem is on the passenger side, and the difference is only towards the rear of the vehicle.

So all around is flush, besides the rear passenger side corner of the sunroof is about 1 cm lower than the molding. I should have gotten pictures, I'll try and shoot some after work today.

Any suggestions on how to fix this? Could I need a new gasket?
