So the weather stripping around my My sky panels is either sagging, loose, or in a couple places it's fully gone. The dealer is telling me the stripping can't be fixed alone. That I've to get brand new My Sky panels to fix it. And of course it'll cost an arm and a leg and isn't covered in the extended warranty. Has anyone else experienced this? Did you really have to get a whole new roof!? I don't get why a new strip can't be placed. TIA
