[pianotech] bushing cloth wear, (was Best Bushing)

Played with it some a couple of years ago. Like Jon said, too 
spongy. I ironed half of a strip (with half original for a 
control) to see how it reacted. I found I could densify it to 
something feeling more like bushing cloth. It kicked around 
the shop for over a year, and I'd check it once in a while to 
see how it was doing. It recovered some small bit, but stayed 
pretty dense where I'd ironed it. I don't know if it's really 
dense enough for key bushings in use, or how stable it is, but 
my test piece has meanwhile evaporated.

Yea, I know, it didn't help me much either.
