I just got a bunch of models for my birthday, all WW2, mostly German, afrika korps. I'm going to use them in a big diorama, so i could use some help in the painting, and weathering. i got one set of ruins, so i as wondering if you could tell me how to weather them, and with what. they are mostly brick walls, and sandbags. i also got a little ambulance, a small autoblinda ab 43, and i was wondering what color to paint it. and i got 100plus troops, half german, half british, and i was wodering if there was simple colors to paint those. Also, they're all 72th scale, and the model shop that i go to, mostly sells tamiyas, which im also trying to only buy. thanks for any help.
