According to the info at Sig, it says that the shrinkage of Nitrate is not as great as Butyrate, but it does not say it is non-tautening.

I have e-mailed Tower Hobbies to try to substitute the Skyloft with silk but I don't know if that can be done. Has anyone used Skyloft with good results.

I have already ordered the Nitrate so can I apply the first two coats with regular Butyrate dope followed up with a coat or two of Nitrate, then the coats of color? I would rather not spend the extra money for Butyrate if it really isn't necessary.

Or should I disregard the Nitrate altogether and just use Butyrate? But then what would I do with the Nitrate that is coming? And also Butyrate continues to shrink and tighten EVEN AFTER DRYING, which Nitrate doesn't. So I think I will try the Nitrate since that is already ordered, and Sig says it is great for covering with.
