I really love to use miliput 2-part epoxy putty. You get a lot for the money, its similar to tamiya but for the price you get 4 times the amount than tamiya for almost the same price. Although i might say that the tamiya putty seems a tad bit better in my opinion. But i really love miliput putty. The thing with 2part epoxy is it doesn't shrink and you can shape it without hurrying to shape it before it dries like regular putty.
I like the wing.
