Spice keyboard overlay repair?

Hi John
If you consider to tear it off maybe the same adhesive spray will work Alberto applied for the classic's instruction label?
I'm sure you must fully disassemble the calculator, take the keys out and then work similar as Alberto did.

Don't know it will work at spices as well. Good luck.
Keep as posted.
