Has anyone found an adhesive that permanently stick polytunnel material?

Have you tried polytunnel repair tape?   I know from experience it works brilliantly on the solid plastic cover and if the mesh type cover is made of the same material, it should adhere..... shouldn't it?

Short of that, something like Gorilla Glue would be worth a try on a test patch.

Clear silicone?

Clear silicone?

I have some tape it works fine, but I've tried silicon, super glue, UHU and some plastic adhesive George had in his shed, but to no avail!

UHU and others are mostly indoor stationary glues. I'd go with Gorilla glue - really sticks to anything.

For whatever reason, my OH put a bottle of it in the fridge on a door shelf, it somehow fell over, leaked, and now I have a bottle of it permanently stuck inside the fridge door
