Dude, you need to talk to Bob(Sensei), hes the silk and dope guru around here. But I can tell you that there will be a significant weight increase, we talked about this alot b4 covering my 40% yak, but the whole purpose for the project was weight reduction, it would have added @ another 3lbs back to my plane, versus monocote. It is what I used on my motor box to seal it up, it last longer than plastic covering and the dope is fuel proof. As much as it sucks to do, you just cant get lighter than monocote. On the other hand, you cant get a better finish than fabric and paint. Talk to Bob.....
