For Monokoting balsa surfaces, I've only ever used it on the tail feathers. I never considered it for the fuselage, but you left no entry points for fuel and oil. You've done a really impressive job. What about the engine area, do you use any urethane or epoxy for fuel proofing? And the same question goes for holes drilled for bolts, LG wires, and tank mounting hardware, do you seal the insides of those?
I've done some nice work with wings, and added striping and such, like the eagle feathers on my Osprey, but always cut those decorations from monokote film and applied them "cold" with ammonia glass cleaner to activate the glue. I've only recently tried the trim Kote, and am impressed with how strong its glue is.
I hope you don't mind my tangent to your topic here, but I thought this would be a good place to compare the differences between Monokote and Ultracote.
My first film coating job was with Ultracote on the wing and tail of a 1/2A Jumpin' Bean, and it came out pretty good even by my current standards. But Ucote has more Cons and only one Pro that I can think of. The Pro is that it's easy for a beginner because the adhesion temperature is far different from the warmer shrink temp, so you can do those jobs separately and avoid some frustration. But you can't brute force it like you can do with Monokote where the glue and shrink temps overlap, really hot. And for a truly wrinkle free job around sharp turns and compound curves, you have to glue and shrink at the same time, which you can do with Monokote. And it still has plenty of shrink left over for re-tightening after a day in the hot sun. But with Ucote, not so much. And ammonia doesn't activate Ucote's glue either, so you can't decorate as easily unless you use the heavier trim film. Also I almost never use a gun, just an iron with no sock. Maybe my iron doesn't get as hot as yours, but the sock slows the heat transfer too much for my preference,
Now I might have to try doing a whole fuselage, since you've demonstrated how. I might try laying tissue on with dope or Polycrylic first to harden it against dents and dings. I'll report on whether that works out or not.
Anyway, this is a great thread and will help a lot of people who turn it up in searches.
Thanks a lot for the tutorial.
