I think the answer to the original question, "how long do I wait" makes a great deal of difference whether one is using Acetone / Keytop or Lacquer. Lacquer will dry much slower and acetone / keytop is playable within the time of a normal service call. This is why I wanted to not mix the topic. If your experience is different I sure would be interested to hear EXACTLY what materials i.e.. lacquers and in what strengths (mixtures) you are using them. Greg </blockquote>Hi Greg,                I recently completed a Steinway D that need 3 applications to get the power I needed for full Orchestra.  Waited 3 days in between each application of 4:1 thinner to laquer.  Excellent results.  24hrs is the norm, but in future I will use the 3 day period if practical. I would only use the keytop material very sparingly at the strike point when my back is against the wall.  1hr. and it's workable.  I don't like the tone it produces at ppp.  FWIW.
