As far as how I painted it thus far? I used the FoW German Grey Spray Primer, a wash of Badab Black over the whole model. Then I went back and block painted in German Grey. And finally a light drybrush of Adeptus Battlegrey. Finally for the primer the Germans used on their tanks I used the sponge method and put on some Burnt Sienna (which is also the tread color). It's pretty simple so far and has a nice result.
I guess my situation doesn't help that I should be getting a shipments of Warlord Games models soon and a bunch of Perry Bro's French Napoleonic's? Man I need to focus on something! And probably not these guys!
