Hi all,
Another week, another problem, driving along at 60mph with the back window open, look in the rear view mirror to find the headlining has come unstuck and half come away from the roof!!

Apart from being an eyesore, I can't see out of my back window.
How would should i go about sticking this back on?? Are any glues that are better for this than others, are there any i should avoid??
Thanks
