Hi everyone. I'm just finishing an airplane up and I've decided to cover it with Sig Koverall and nitrate dope. Having not used this covering for several years, I'm a litte rusty on the process, so I just wanted to clarify the standard process for putting this stuff on properly.
Ok, heres what I can remember:
1. Apply 2 coats of unthinned nitrate dope to framework (except ribs, attatch cloth to ribs after shrinking the cloth)
2. Lay cloth down, apply two more unthinned coats to secure the cloth to the framework
3.Thinthe nitrate dope about25 thinner and 75 nitrate, using sig thinner
4. Apply 2-3coats to seal the cloth and fill the weave
5. ApplySig supercoat and color to finish off the model, orstart painting right on top of nitrate dope to fuel proof it
Can someone maybe correct me on number 1, I read and watched a video and they both stated not to attatch the cloth to the ribs until after its shrunk, and the reason being so the cloth can shrink the way it wants to, and if its tacked down, it could be "restricted" and put an unwanted warp or twist into the wing.
