Yes the wing/plane is already built. The seam of the wing is very clean, the whole plane is very clean for that matter. This guy built the plane, flew it a few times and decided that he didn't like it. He designs and builds his own planes. I was surprised to hear that he used 5 min. epoxy, but I trust what you guys are saying. I looked up 5 min. epoxy and it has a strenght of 1500 psi.
