Q:Where to buy Glue to wrap headliner?

I wrapped my headliner with the 3m super77 and it's mega crap! Every time i parc the car and it sits in the sun for 3-4 hours the material starts to peel of the headliner and sag. It's driving me nuts! So i ask where can i buy good glue in a spray so that i can rewrap it properly so it won't sag anymore.

Any help is greatly appreciated
Cheers

I used 3M super 77. I have it for 3 years with 0 sagging. It's probably your technique.

Are you sure you installed it right after reading the instructions? Spray both the fabric and the headliner, wait an hour or so then put them on?
