RE: Custom Checker pattern steps?
I would cover the wings first. Then use the solvent and put the squares on. I did this but used Ultracote. I ironed them on. I would follow the leading edge on the swept wing. Keep the squares parallell to the leading edge. I don't think they would look good skewed. They would also be harder to lay out. Every one of your other ideas seem fine to me. BTW I like the white/flourescent green idea.
