Hi I also had this prob with the pealing rubber grip on a F5. I sent the camera to the local Nikon repair center and they fixed the grip within a week. They acctually did't glue it back , the mounted a new rubber part. I don't recommend try to glue it back. You maybe will risk to loose the warranty coverage. The repair as been done under warranty (after 2 1/2 year)! Hope this help Peter
