I'm fairly new to all of this ,but I've had success with both Monokote and Ultracote(oracover). I've also used Econokote on foam with no problems. I think Ultracote has a wider range as far as heat when applying(start fairly low, higher each time you tighten it). Monokote seems to stick to itself better(when doing trim schemes).
I haven't tried any of the Coverite film, tissue or fabric.
You might build a small wing section to practice on as far as how much heat and how to do wingtips.
Hope this helps
