Another quick update...
I'm deviating from the instructions a bit to make painting easier. And thanks again to Brandon for pointing out the wing-orientation gotchas, invaluable info! I'm doing my best to keep the "right sides up." :-)
Hit the wings with some gray/white paint after pre-shading. I'm going for an overall "patchwork in-the-field repairs" look so decided to mask the markings (using the sticker decal sheet as the template) rather than use the decals to get some overspray and general messiness. Then started picking out various panels with darker and lighter grays and some yellow.
Next, I'll seal everything with Future and then start the weathering in earnest (panel line wash, filters, dry-brushing, chipping, and overall color adjustments as needed).
Thanks for looking! And for those in the U.S., hope you have happy and safe Thanksgiving.
