I put the first coat of clear nitrate on the Coyote fuselage this afternoon. It wasn't long before my shop reeked of dope. The window is fixed, so no fresh air available. In little time, the smell permeated the basement and worked its way upstairs. My wife came home and was not a happy camper. Said she could smell it outside!
I have one more coat to put on prior to covering with silkspan and probably a few more to seal that up prior to painting with Rustoleum. I don't dare do anything at this point until I can figure something out.
It looks like my doping days are over when this plane is finished. The tail feathers are covered with Ultracote and the wing is next. I only have to dope the fuselage.
What other product can be used instead of clear dope that doesn't smell so intensely?

If your looking for fuel proofing dope isn't that great anyhow. I have done a finish for years much like Allen Brickhaus wrote about in an article published in flying models.
Basically covering the fuselage with 1/2 oz fiberglass applied with water based Urethane. He used spackle as a filler before going to primer, I skip that step. Primer, well sanded and Rustoleum paint. I'd use auto clear but have no way spray it and live.
I've used this method for years and many of my planes are years old and not fuel soaked or falling apart.
While it is not as light as a doped finish it isn't that heavy either. If your not competing I have never found it to be a deal breaker on finishing a model.

Tell her it has the same smell as fingernail polish and it's remover.

I'm sorry, I don't understand the question. The pleasing odor is half the point. n~
I've done a couple throw-aways with Duplicolor primer on the raw wood followed by Rustoleum. The result looked about like dope followed by Rustoleum. I've used Rustoleum a few times, durability isn't great, can't do a thing with the flaws, and repairing it when it's damaged is probably impossible. Dope makes a much nicer finish that's stupid simple to fix flaws and fresh dope goes over old dope without problems.
Duplicolor auto touch up paint in spray cans is a fair substitute for colored dope. It tends to cover faster, dry faster, stinks less, and it opens up some new colors. Seems to be more fuel proof than Rustoleum, maybe more so than dope. Still have to use something to shrink/attach the covering, I use dope for that.
You might want to look into the Polycrylic method.
PS I do all my painting outside or out in the garage.

Can it be used to apply silkspan?

Onto a solid surface, yes. That's how I cover my fuselages.
One member of my RC club likes dope finishes, and sometimes when he's at that stage of a project he shows up at the flying field with dope, brush, thinner, and plane and works away and chats while the rest of us fly.

All of my family do not like the smell of dope, even the dogs. But, after a while you hear no complaints as they soon get used to the smell. Dad related a story to me about that getting used to a smell and have learned that I agreed with him. Drove thru south west Kansas across Oklahoma and north east Texas. They have feeder farms for cattle in which they are getting ready for market then the dinner table. If you lived there all the time you never think of the odor that is in the air. And talk about odors, don't ask about when I was playing with F2C planes. I would come home from practice and the little house we had there were the stairs to the basement. Had a shower down there where I would try to get presentable to the wife again. Washing machine and dryer were down there also.
