I think I have settled in on a color. Last night I figured out that I wanted a dark color so this morning I took a look at my paint stash in the house and found what I needed. The bottle has been opened but I don't even remember what this paint was used on. This is the Tamiya XF-63 German Grey acrylic paint so it will go on flat until I hit it with the X-22 clear. Under directions from Tamiya's modeling team I have been using off the shelf lacquer thinner to thin their acrylic paints and it's been working out.
