At the end of the presentation (90 min) the note had come up quite well.</blockquote> This was the original use of both lacquer, and, much later, various kinds of "keytop" and acetone.  The latter was actually introduced at the Hall for specifically the purpose of "bringing up the tone" a small amount while a salesperson and customer had coffee/lunch...for which use, it was/is entirely appropriate.  The problems arise when, like other hardeners, it is used without thought and/or discipline. <blockquote type=cite class=cite cite="">     I'm going to try this on  20 year old B that I have just regulated .Hammers reshaped with very little wear .Sustain and power are good but the attack is very weak and the pianist would like this piano to come up. </blockquote> Nice and thin solution; very small drop; and a good deal of patience.  You'll be just fine. Best. Horace <blockquote type=cite class=cite cite="">    Mr. Shandall also outlined other methods of his voicing techniques that is part of a longer class he is offering next week at the upcoming pacific northwest convention.     We had a nice crowd on a very snowy night and Steinerts was very gracious with their hospitality.     Tom Driscoll RPT         </blockquote></body> </html>
