I built mine and then covered. What I do where the tail makes a 90 degree bend to the fuse and rudder and also where the wing meets the fuse, I cut a 1 inch strip, and folded it in half so I had a crease at 1/2 inch. Then I lay a little bead of thin CA in the corner and lay in the piece. Then iron it on carefully so the ca doesn't come out. On the wing you have to use short pieces. I then cut the wing covering to come right up to the fuse, and the fuse covering to come right to the wing. When you iron those on, you don't have much of a line, but there is no bare wood and no patches. The initial 1 inch covering can't be seen accept the outline, and noone sees it unless you point it out. It works great. You only end up with a seam in the very corner that way.
