Actually, there are 4 basic flavors of dope.

Nitrate; shrinking and non shrinking.

Butyrate; shrinking and non shrinking.

Take your pick.

Do you know the brand of dope? It might have a part number I can trace. Most (actually, I think there are only two companies making dope today) manufacturers will say 'non-tautening' or 'low shrink'. By it's nature, nitrate tends to shrink less than butyrate, especially over time as the years go by--butyrate can slowly tighten as it ages, especially if the airplane is stored outside rather than in a hangar.

As a reminder--only butyrate is fuel resistant, in spite of it being labeled 'fuel proof' it can be damaged by too much exposure to glow fuel.

Nitrate, though, is not in the least resistant to glow fuels and produces a horrible mess upon exposure. Ask me, sometime...

At the risk of being too much too soon, remember, almost anything can be painted over nitrate, including butyrate. Not much will successfully stick to butyrate, and nitrate over butyrate will not cure.
