This was a first for me.

 

Some one had glued this key top 8-10 years ago.  Pictures attached.  The
owner said the man who did the "repair" was a golf buddy of her husband's
who "tinkered" with pianos. He must have used some kind of glue that was
designed to expand and fill gaps. It had attached itself to the neighboring
keys, causing two keys to go down at once.  It was a soft kind of crusty
stuff that scraped off fairly easily with a pocket knife. 

 

She said that it expanded this year like you see in the picture.  I can't
see how that would happen.  Not that it matters at all for perpetuity, but
is it even possible to have a delayed expansion like this?
