I covered the wing of an 80 " arrowbile with stiks-it and polyester and then gave it three coats of of WBPC & baby powder. I just can't get the covering super tight over the open bays of the top wing. I was thinking of using a coat of Nitrate dope over the open bays to tighten the material up. The compatibility chart shows the two chemicals should work ok. What do you experts think...Thanks Mike
