I will give that a try! Thanks Katie.

Been using the silicone for years, no problems (yet?).

Do the centre keys have the same snap as the edge keys?

Geoff

The center keys are working perfectly! No touch and feel difference to the other keys.

This was a good question, which shows the knowledge of a real master restorer.

After a while I needed to add glue also to the center keys, because the ENTER key didn't keep the snap. But now it is stable since months. It is important to hold the two boards tight together until the glue is fixed.

That's one small step for a man - one giant leap for mankind.
