Hi, Barbara

I got my shellac flakes from this place on the net -- I just checked that 
they are still there.

http://www.woodfinishingsupplies.com/Shellac.htm

They seem to carry Behlen products, which Ed suggested. They also have 200 
proof denatured alcohol, which has no methanol or water in it. 9% 
isopropyl, and a couple of other things in it. I've used bulk ethanol from 
the liquor store, 190 proof, and it works well. People have told me that 
some states don't allow 190 proof to be sold, though.

I did try very dilute keytop/acetone on a few notes once, and I must admit 
that I heard that spicky clicky sound ever afterward, even after needling 
-- though I didn't go so far as to try to soak it out with acetone. It was 
after that experience, and after reading a hint from Horace saying that 
Steinway used to use shellac (they'd just use whatever their finishing 
department used) that I tried shellac and really like it. Nontoxic, as 
well, especially if made up with pure ethanol. Nice little lac bug -- 
friend of man.

The color -- well, one doesn't want the hammers grossly stained, like they 
would be with some shellacs, but having just a little color in there (like 
the ultrablonde color) isn't totally bad. It lets one see exactly how far 
the solution is wicking. And, like Horace says, how they sound is what 
really matters.

Regards,
Susan
