If it is from Hangar 9, it is likely to be Ultracote. Try carefully going over it with a heat gun (if you have one for use on covering use it) a little at a time to get it to shrink. Don't forget to try to shrink the bottom and top equally, you can put a little twist in the wing.. If you don't have a gun, get a covering iron, and start with a very low heat. I have a little thermometer that goes on the face of the iron so I don't start out too hot. Ultracote has a lot of shrink available in it, so don't give up yet.
