My brother asked me a question that I don't know the answer to. He's building some hand-chuck gliders and covering them with tissue. The tissue needs to be doped with a thinned dope mixture, naturally.

He asked me if acetone could be substituted for dope thinner (presuming he's using Aero Gloss butyrate dope). I'd never heard of that, but thought I'd ask.

Has anyone ever come across this before? Is there any substitute for butyrate dope thinner?

Thanks,

Bob
