This is Fujimi's 1/72 scale A5M4 Claude in the kit's provided markings of a Soryu based aircraft, Dec. 1940.
Clear orange was mixed into aluminum and steel metalizers, and sprayed on to simulate the possible protective amber varnish. A final satin clear was applied overall. Masks for the Hinomarus were cut from masking tape using a circle compass cutter.

Jack
