Alltrax, are you Dutch or just use imported stuff? :) The little I can read, it says "special glue".
Could you unfold that tube a bit more? There's some Uhu stuff to be found at specialty stores but it would be helpful if I can get the exact type to ask for. I've tried both CA and 5min epoxy and to my amazement the plastic just wouldn't stick to aluminum. And epoxy usually sticks anything to anything. :)
Maybe I need to sand the enclosure for it to stick, I'll try but I have a lot of cleaning up to do as is with all my failed attempts.
Do you get glue squeezeout? ? Cause I can't see any on your pictures and there's no lifting to be seen so I'm assuming some squeezeout and wiping?
I'll definitely try other plastics as well, I just need to find some around town.
