Thanks again for all of the comments! MH712 is progressing nicely and I'm getting lots done each time I'm in the workshop. With the camo finished, I spent some time with some painted details. The Sky fuselage band was masked, pre-shaded and painted using the Hataka paint. I thinned it with 70% iso alcohol and it behaved ok.
I almost forgot about the paint chipping step. The thin layer of hairspray is now sitting under multiple coats of black, Ocean Grey and Dark Green and I wasn't sure if I would be able to get the technique to work. Using a brush wetted with water, I brushed and brushed and brushed and brushed until spots of Alclad Aluminum started appearing. It was definitely hard work for such minimal effects... I'm gonna have to explore other chipping methods for the future.
Taking a break from the chipping chore, I masked and painted the yellow panels on the leading edge of the wings.
Back to more chipping. The difficulty was perhaps a blessing in disguise. It forced me to accept very subtle results, which is not a bad thing. Definitely more preferable to too strong of an effect. I stopped after this point, afraid that more aggressive rubbing with the wet brush would force a mistake.
The tips of the Hispano cannons were sprayed with Alclad Stainless Steel. Although not as nice as AM brass barrels, they look acceptable.
Careful inspection of the camo pattern revealed some little defects that were carefully corrected. When all was in good order, I sealed everything with a clear gloss coat. I used Alclad Aqua Gloss for this step.
To avoid messing with the long skinny decals, I decided to paint the thin black wing walk lines.
This is a good stopping point. The next step will be applying the stencil decals but that will have to wait. I have some fishing to do!
