I have used this tape indoors outdoors where it will not get wet or be in direct sunlight but will be exposed to heat and cold. Installed and pressed in firmly on a 65F day in September. Now in December from 15F night it flakes off. Very disappointed considering what was said. Just updated in March with a few photos: I used masking tape to trim the fiberglass screen. So part of it was taped to duct tape and part was on a fiberglass screen (and it would have to be sticking to itself through the little holes in the screen if it wasn't attached to the screen). As you can see in the photo, it just falls off due to the very poor adhesion. It's a waste of money, at least for cold-weather applications.
