Lacquer  heads 
  Come on now get your nose out ta da microscope maan. This is  not all that 
difficult & there are no magic lacquers it's jsut what's  available to them. 
If you've found straight nitro cellulose lacquer then  thin it and apply it 
until your familiar with the result. 
   I think Patrick said Wurdack. He's right. Its a high solids  lacquer 
designed to be sprayed hot at about 150 degress & has a distinct  odor. It takes 
many moons to really get hard ,just look at the the black  finishes coming out 
of the plant where the buutons hit the rim.
 Out here in Calif We have US cellulose  brand  that most refinishers in this 
region use & it works fine. 3 to 1 is a  pretty stiff solution & I usually 
use it as my intial dose of Stwy hammer  lacquer but it depends on the initial 
density I percieve inherent in the felt as  they come out of the box. I use it 
on Many different kinds of felt.  Whats the solids? I dont' know & don't 
really care as long as it makes the  hammer stiffer. I'd avoid a lacquer that had 
any varnish or other non lacquer  type additives.
 Use the ventilation all.

I have only been  able to locate two lacquer products sold locally. Neither 
had this spec.listed  on the label. By calling the company I found that the one 
product I have always  used when applying lacquer, "Deft" Clear Wood finish, 
was nitrocellulose lacquer  with a solid content of 26% by weight! The other 
product I located made my  "Watco" was also a nitrocellulose lacquer with 
26%-27% solids by  weight.

Could this mean that a 3:1  solution of "Deft" lacquer was more like a 1:1 
solution of "Steinway" lacquer,  since both would be around 6% solids ( by my 
rough  calculation)?

Now, I am now  wondering how meaningful the various opinions are about the 
strength of the  lacquer solution 15:1 3:1 etc. , without a specification of the 
solid content of  the lacquer being used.
