I just applied a base of Russian green, the final scheme will be a heavily worn winter wash. As you can see, I've started experimenting with the wash on the bottom of the hull - I'm using a coat of undiluted white gouache rubbed off with a scrub pad or a damp sponge. There is still a lot of detail work to do on the exterior, just need to let the paint cure first.
I left out some of the drivetrain bits (where are the radiators?) and didn't bother painting some areas. As you can see, very little is visible through the hatches. I glued the hull on permanently because it wouldn't fit otherwise. The rust is Sophisticated Finishes. The rough paint was achieved by blasting undiluted Model Master Russian Green through my single action. Aside from that, I added weld detail to the front of the hull, textured the turret with liquid cement, and added the turret casting seam.
Yes, I know the rounds are mounted backwards on one side of the interior. And yes, I took some liberties with some of the colours for effect. I'm not a rivet counter by any means.
Oh goody, 20 road wheels to paint by hand.
