RE: Silk application
To perhaps correct a few of the myths.
There are 4 flavors of "dope"; Nitrate, taughtening & non taughtening. Butyrate, taughtening and non taughtening.
Nitrate sticks to almost anything, and you can put almost anything over it.
Butyrate does not stick well to most things, and the only thing you can reasonably put over butyrate, is butyrate, because butyrate continues to shrink; forever.
Aero Gloss is neither. It is some chemists dream mix that is easily manufacturable.
Real silk IS available from Thai silk, for a few dollars a yard, but is somewhat pre shrunk, so that should be considered when covering. (5mm Momme is what I use)
