Gentlemen,

Considering purchasing a gallon of Nitrate Dope from Aircraft Spruce or Wicks.

Not sure which one to get.
Plan to use it to seal bare balsa, flat balsa surfaces (flaps), and on Silkspan and SIG Koveral over wing ribs.  My guess is a Tautening dope. 

1) Should it be a Tautening or a non-Tautening dope?

They advertise Randolph as a;
  Nitrate Clear High Solids

2) Is the above the correct for a Tautening dope? 

3) What does the 'High Solids' statement mean on the label?

4) Is there a Shelf-Life to the Nitrate dope?

Thanks for the info.

When I was a kid I used nitrate dope on one side of silk wing and didn't paint the other side.  Looked like a barrel hoop in the morning ....
