  On a hot day in the shop 80 degrees or more The lacquer solutions will 
dryquickly enough so that that the sound is changed within an hour, Except on 
the largest bass hammers that were really soaked this it takes two hrs. 
Remember It's not cured  so I don't hammer on it but I can play it enough to 
get a semblance of whether I got the solution dilution close to my target 
sound. It changes a bit more overnight and breaks down some as the next 
tuning gets pounded in. If it's still too edgy a little acetone on the top 
will wash it in a bit and won't take long to work with. If it's not enough 
repeat with another light application.
   With any of this , as you know, it takes time to dry and it's nice to have 
the piano in the shop which is not always possible, but I like to live with 
the pianos sound over the course of some days while working and refining 
other things when possible.
