I have a recently purchased 1994 Excella and when it rains I have leaks on both panoramic windows. I have received some advice but I'm not sure what the best solution is. I've been told to have an auto windshield repairman pull out the windows and seal them since they are like auto windows. I've also been told just to buy some silicone for windshield repair/sealer to solve the problem. While both options sound reasonable, my concern is the source of the leak. The way the windows are installed makes me think the source of the leak is not at the window but could be above or where the hinges for the rockguard are attached. Any suggestions would be greatly appreciated.
