Hi Al
  Oh I see how it is holding out on your top secrets again AL.  uh huh. You probably no how to make moonshine too.
 
 
Good to know

Dale,
 
I only use the MEK to cut the NC to about 25% solids. It's a good solvent and doesn't hold much water. I use a urethane grade MEK which has less than 1% water. I then dilute the NC solution  with acetone for use on the hammers. The problem with acetone is it can hold much more water than MEK, and you never know the water content.

  All I've heard about MEK is that they are baaaad for us and they are in many paint products. Limiting our exposure is always the goal be it lead,acetone,dust or whatever.
  I cut the lacquer with acetone cause it flashes off quickly and it's important to do this out side or with a mask on & then leave till it dry's. I presume meks flash off quickly?
 HEy,My grandfather chain smoke unfiltered camels till he was 50 something then quit abruptly & lived to 90. I hope I got his genetics and no I don't smoke!

I don't eat it, I just apply it to the hammers <G> 
 
Not nearly as bad for you as the CA glue we're using. MEK is the most used clean up product in paint chemical labs. I know a few chemists who used it most of their lives and lived to be over 80 yo with no harmful effects that I know of. Of course "That I know of" being the operative words here.
