Quest X-30 Aerospace Plane Part 8, Fin & Shroud Prep

The two wing pieces are glued together.
As the instructions showed, check to be sure the root edges are lined up with a straightedge. Sand the root edge with a block.

The edges of all the fins will be exposed, the printed fin covers don't wrap over the edges.
Just the edges were filled will CWF and sanded smooth. The picture shows the application of the CWF before sanding smooth.
After sanding the fins were stacked and the root edges sprayed with Grey primer filler.

After almost 20 years of storage, the main aeroshroud card stock had soft folds and wrinkles. Leaving it flat in a heavy book overnight didn't smooth the wavy surface.

I used a dry iron and it helped. The instructions say you could use an iron on a steam setting, but I wouldn't recommend it! I tried some steam and it made shallow dimples in the surface from the holes in the bottom of the iron.

After ironing there was still an uneven surface.
I can only hope these will smooth out when the shroud is rolled into it's final shape.
