It's meant for patching holes in a tent.
It works. My tent was full of tiny holes made on a windy day. The oak pallet fire would pop a good one and the tent took it.
Took a while to patch every little hole but my tent is dry and it's raining. The tape is clear and you can't see where I patched via a picture. There are lots of them. Hard to believe the camera can't see them.
