I am using this material to cover vintage model airplanes and vintage model sailplanes. I finish with nitrate and butyrate dopes. Since I am building some pretty large sailplanes I wanted fabric in long enough lengths to cover the span of the wings without having to piece fabric together. I am happy with this product!
