Jim, I love ya, but I really would love it if the question I actually ask is answered. The jar of suspected Nitrate is all I have, and is what I want to use, so throwing it out is not ideal.
I have heard, that if you put the wrong thinner with one or the other dopes, the result curdles up. It would seem that someone can provide me with the combination to test the various bottles of dope.
BTW that flying wing you sold me flies great!
