I think the Pianotek stuff is ground up plexiglas. There's artist's fixative (in bottle or spray), hair spray, artist's picture varnish in many variants, clear nail polish...acrylic floor wax? Enough for a lifetime of testing, given the funds.

As I recall he said it was helpful to build tone without becoming "brittle" (the tone, that is). Since I have a piano problem similar to Israel's, I've ordered some B-72 and will try it next month. Pianotek's hammer hardener is described as acrylic. I have used it, and have found it acceptable (haven't used it that much). I like it better than actual keytop dissolved in acetone, which I have not used myself (only followed other people who used it). I wonder what differences there are between acrylics. There is also acrylic lacquer.
