This is the Mac 1/72 kit of the Phonix D.1. I built it right out of the box
and rigged it with invisible thread. To paint the upper surfaces I first
sprayed with Tamiya flat Desert Sand and then used a craft acrylic (JoSonja)
burnt umber mixed with a lot of water and dabbed on with a damp Q-tip. I
gradually used less water to create the darker areas. If you work fast
enough it goes on "wet on wet" and blends together nicely. Not sure how
authentic it looks, but it was fun to do!
