Alternative Adhesive for Digitizer

I am working on a 2-in-1 laptop tablet and had to disassemble the screen to look at something.

I need to adhere the digitizer back to the frame, but the frame is quite bent in the corners. 3M adhesive is not working. To be honest 3M adhesive strips have never worked very well for me, and the screen has always come forward.

This particular laptop is on its last leg, and WILL NOT need to be opened again. Can someone recommend a glue and adequate clamping mechanism to get the digitizer on tight?

Thanks
