[sdiy] Rubber contact keyboards

[Tom Wiltshire]

The link that Travis posted has all sorts of useful stuff, including 
some kind of gloop for repairing rubber contacts:

I've been hunting around for something like this to fix the appallingly 
unreliable keyboards on the Korg Poly6/Poly61. The commonest fault on 
broken Polysixes (which for some reason I seem to be a magnet for) is 
dead keys on the cheap plastic keyboard, followed by the famous memory 
backup battery leakage problem.

My SH101 has a dead key from the same cause, although the keyboard is 
better built overall by far.

Has anyone had any experience using this stuff, or something similar?

Tom
