I used super glue gel and it is still holding after 5 years. I used medium black binder clips to hold the trim down over the lip overnight to allow the glue to set. Just be careful not to glue the clips to the material and also be careful not to damage the material with the sharp edges of the clips. The medium clips allowed me to clip all along the contours of the pocket. The gel formulation helps to keep the glue where you put it although they do have a new pen applicator that might be even better than the gel. I think I would try the super glue pen applicator with the black binder clips for support, if I ever had to do the same job again. The super glue does seem to make the edges of the material a bit crunchy when it dries, but that is inside the pocket and out of sight. I found that other glues don't stay attached when the heat goes up. They get gooey and they just can't keep hold. Super glue is not affected by the heat. I just remember when an upholstery shop tried to fix a headliner in my wife's Jetta GLI and the glue would get gooey as soon as the summer heat baked the interior of the car. The summer heat is what dislodged my door pocket trim. I was parked at an amusement park on a hot sunny day and even with my sunshield in place and the windows cracked, the temperature inside the car caused the material to pop off of the lips of the pockets.

I think it might be like always going back to that same bad relationship with an ex girlfriend.
You feel you love them too much, or you are just too stupid to know any better.
