More on dope

I was looking through supplies for "real" aircraft and found clear dope for $29.30 a gallon. That certainly beats over $5 for 3.5 oz at the LHS. I remember going to a local airport as a kid to buy dope by the gallon. We used to add talc to make a sanding sealer, as well as using the clear. The dope comes in two types: butyrate and nitrate. Does any one know which type is used for models? Hmm... I wonder if I could use the alcohol dissolved analine dyes from my wood shop to color it.... Thoughts?

Both.

Nitrate first to attach & stretch covering.

Butyrate second to make the covering fuel proof.

Yes. I had dyes like that when I was a kid. Never used them--just had read an article and got them from a friend's father. Circa 1965.

*But* remember Randy Butyrate over Nitrate is OK. Put Nitrate over Butyrate and you'll be sorry :-)

Just a few cautions, though. clear dopes (both types) sometimes come tinted slightly. They also are sold as taughtning or non-taughtning.
