Up next were the hinomaru. With the introduction of the type 52, Nakajima moved in the upper wing hinomaru slightly and used a 30mm white band, as compared to Mitsubishi's 75mm band (thanks to Ryan Toews for this detail). I cut my mask out of Oramask 813 (blue) as it is more stable and rigid compared to 810, especially with such a narrow ring. 813 doesn't work well over compind curves, but for the wing this is not an issue.
First, I laid the outer mask on and then sprayed the perimeter an off white. Then I added the ring mask and sprayed the red. The white rings were usually overpainted with dark green, so I masked the red, pulled out the thin ring and sprayed hairspray and dark green. My masking method wasn't great, and resulted in imperfect circles, which I covered up with a bit more shipping of the dark green than I would have liked.
I followed the same procedure with the fuselage hinomaru and they turned out ok.
