I mostly agree with the quote, with one important exception: nitrate will either shrink or not shrink depending upon whether or not the manufacturer added a plasticizer--and the two major hobby suppliers don't tell you! Sig Nitrate shrinks very little. I got some Brodak thinking it would, but it turns out it doesn't shrink either.

The only source of nitrate dope I know of that will shrink is Aerodyne. But the last can I got from them had a rusty tint to it from the drum the original supply came in. I don't like it because it's impossible to brush it on without getting very obvious brush marks.

If anyone knows a source for straight, unadulterated nitrate dope in quart sizes I'm very interested.

Aside from the Aerodyne nitrate, the only dope I've used that definitely shrinks is Sig Supercoat, but it's a butyrate.

Shrinking is really important to me because I'm trying to use silk from a fabric outlet (Thai Silks) and their silk doesn't shrink much at all.
