RE: POLYESTER CLOTH
I used some Hobby Lobby Dacron to cover a VK Sopwith Camel. Really liked it except for the need to use Nitrate dope (very smelly) to seal it. Used Balsarite fabric for attaching, shrank it with a heat gun (had to reshrink after nitrate dope). Once sealed I put on a coat of clear butyrate dope and painted with Latex. Five years and not a wrinkle.
