I read a post a while back and someone had actually talked with a rep or someone like that at ge and they said " not outright because they coulden't " that Ge1 is the exact same silicone they make for all glass. one line gets an all glass sticker one gets the other. I myself and MANY others have used it for years with zero problems....It is not a bad link. And yes it is about 3 dollars a tube.
