Answered my own question. The repair stuff is called "Aquadag E":

Should work a treat in this application.

Hello,
this kind of keyboards was made using small pieces of conductive rubber to
close the circuit designed on the PCB.
The rubber was an uniform compound, so even with severe usage, i.e. high
