I got the rear wing on! The glue got everywhere, but it came off with thinner. First I glued and spot welded the beading along the top of the wing and the outer shell together, then I glued these to the rest of the car. That way I got all the messy gluing done in one go and I could use the beading to get the outer and inner panels correctly located to each other. The only visible differences from the earlier photo of trial-fitting is the number of clamps present and the fact that the beading is there this time. Something not showing is that one of the clamps got unstuck and fell down inside the front part, behind the B-post. I hope I can get it out... This and the front wings are nice parts of the project because other people than me can actually see something has happened since last time. :)
