Spice keyboard overlay gluing

[gentzel]

I recently picked up a 34C to replace the long-gone one from my high school days. It was actually in very good physical condition with one caveat - the keyboard overlay had started to detach from the top case. It was only connected for about the top key row and bottom key row, with the overlay "arching" up in the middle.

It was fairly easy to slip a plastic dental pick through the key holes and gently pry the top and bottom loose, detaching the overlay with no damage. But how to best reattach it?




I found this thread: https://www.hpmuseum.org/forum/thread-19356.html but no good answer was posted.

So is there a glue people have found to work well for this? Obviously want something that will stick well to both types of plastic, and which will be thin enough to allow a flat application.

Thanks.
