Cellulose acetate butyrate dope was developed for use on full-scale airplanes.
It's lightweight, fast drying, high-shrink lacquer-related formulation makes it an excellent finish for wooden model airplanes.
Butyrate dope is very flexible, making it the very best paint to use on a model that has open areas in its structure where the covering is unsupported. It will not crack or split fromvibration or flexing.All SIG Supercoat dopes can be brushed or sprayed on with good results.
