A brief update--here is the assembled wing in the process of finishing. The surfaces have nicely molded, very delicate, corrugations on the upper and lower skins. In order to make the seams as invisible as possible, the moldmaker placed each seam at an area that is easy to fill without losing the grooving that represents the corrugations. The wing is molded in five pieces, the gull-shaped center section and four outer panels. After tweaking the center section just a bit to get the dihedral right I glued it all together.
Here are two photos of how I applied the filler to each seam. I masked the corrugations off on either side with thin tape and applied the filler, sanded, repeated, etc. By using this tape I kept my sanding and filling operation from obliterating the surface detail.
