Thanks for the positive comments! Greatly appreciated! Now that the topside green has been established, I should now do the chipping before more layers of paint are added. The hairspray layer that was sprayed onto the Alclad Aluminum is vulnerable to water. By brushing a wet paint brush over the area, the foundation for the green will be compromised and will begin to disintegrate, revealing the metal finish underneath. I've found this technique to be highly variable and after a few minutes of wet brushing, I wasn't satisfied with the results. I think I would've accepted the results if I were doing a highly worn Japanese bird but that is not the effect I was going for.
I let it sit for a day before making the decision to repair the green and do my chipping using another technique. I gave the chipped areas a coat of light grey and did my normal pre-shading routine.
The IJN is put on over the preshading. It's finished off with a bit of postshading using a slightly darker green. Another downside to the hairspray method is the physical disruption of the surface paint layer. You can't quite make it out but there are imperfections in the paint finish where the chips were. I tried to smooth this out using fine sandpaper and micromesh but I ended up making it worse... I couldn't eliminate the edges of the paint layers. I'll have to disguise these imperfections with chipping later on.
I decided to add the white-bordered fuselage hinomarus at this point. Japanese insignias are simply circles so masking them is pretty easy if you have a circle cutter. I used a micrometer to get dimensions off of the kit decals and cut two sets of two circular masks.
The larger diameter mask outline is applied first. I put on an irregular coat of white to serve as a base for red.
The red is a mixture of Tamiya Red and Brown.
After the red has been given sufficient time to dry, the smaller diameter circle mask is placed within the bigger circular outline. This is the trickiest part of the deal... lining up the circle to ensure that the outline is uniform. I drew crosshair lines on the masks to help me line this up correctly but they were of limited use since the curling yellow tape was difficult to control.
The hinomarus are finished off by spraying the white border. At this point, I'm crossing my fingers and hoping that I have reasonably concentric circles.
The moment of truth as the masks are removed... hmmm, not bad! A little bleeding has occurred but this side seems to have been a success. It's a good idea to save the masks after painting to be use for paint touch-up.
