For those of you who are doubting this tape because Gorilla Glue hasn't worked for you, you might want to notice that in their FAQ section it states that the adhesive used on the tape is NOT Gorilla Glue, but just a different formula they created for tape. It sounds like it is a similar compound to what is used on duct tape, but as they said it is "twice as thick", and it seems like they improved the overall strength of backing so it is more durable, but harder to tear by hand.
