The only tape I'm using is around the back glass for that very reason. I'm probably being overly cautious, but I've always been a big believer in spending a bit more prep time and have an easy cleanup. We shall see how this FROGTAPE with seep-proof technology does. I was able to run the edge of the tape to the SIDE EDGE of the rear glass trim, so as long as I don't really soak it, I'm hoping it will pose no problem.
