The stuff is from Pianotek. It is a lubricant with silicon polymers that also temporarily swells the felt and allows resizing. We have been playing with it for about a month here and it seems to work well. We have done experiments with rebushing after use and it does not seem to affect future adhesion. So far we have restored a more solid feel to a number of sets. We are about to try it wholesale to the bushings of our performance practice rooms. We have also used it on new bushings as way to lubricate and more consistently size the new bushings. So far, I like what I see. ____________________ Rick Florence Senior Piano Technician Arizona State University School of Music -----Original Message----- From: caut-bounces at ptg.org [mailto:caut-bounces at ptg.org] On Behalf Of Jim Busby Sent: Monday, October 20, 2008 10:31 AM To: College and University Technicians Subject: Re: [CAUT] S&S Key Bushings Hi Chris, What is "VSProfelt"? and where is it obtained?
