Not too often I endorse a product but I found a product by Pro Form out of Toronto that works great sealing window leaks. It's call PF 218. It's a butyl rubber that comes in a caulking tube. It's the same colour as the original window rubber. Never really hardens so it will move with the body and windshield..very happy with the results I've gotten with this. Can be cleaned off farily easy if you want to ...unlike silicone. Hope this info helps somebody...
