Long ago, Ed Nisley got a cheap “desk calculator” with a vital function: it beeps cheerfully with each keypress. Nothing lasts forever and the aluminum dress panel around the keys had been gradually working its way loose.
The dress panel was held in place by what was once a quick-setting gooey glue that had long since fossilized. Although it gave up on the aluminum, it was not going to come off the calculator body without more struggle than seemed warranted.
So I stuck the new glue atop the old glue and hoped for the best. You can see traces of the old glue bead through the sheet.
If the adhesive sheet also gives up on the aluminum, I’ll try some fancy 3M 300LSE adhesive.
