This weekend I put the base color covering on the second wing. And therein lies a problem. The second wing turned out way way better than the first. No wrinkles. None.
If you hold it at an angle to the light, you can catch minor stretch points where it adheres to the wing ribs, but try as I might, I couldn't get them to show up in a photo. So now I have a problem. I have a completed wing that looks ok that I might have to redo just because it will annoy me to no end that it isn't as good as the other wing. I am going to wait and see how the second wing turns out though.
The key to covering, with Monokote anyway, is to go slow. It took me about five hours to do the two sides completely on the second wing.
