In my case the adhesive still sticked to the silver border and the metal bezel. I actually reused it as it still sticked quite good (not as good as before of cause). I only used some drops of glue in the corners and fixed them with clamps for hardening of the glue.
I had no problem with reapplying the gasket as it fits nicely into the notch.
A big THANKS to Walter! It is in deed not easy but thanks to this detailed instructions I got it working!! :)
