Thank you, I've seen that picture before, I think its pretty unusoal to see an M1 with rust like that. It must have been in theatre for some time. As far as rust goes I think I'm just going to stick to the tracks when I get hold of some spray rust. I'd like to add a little shiny bare metal in places if correct as I believe it will make for a more realistic metal look. Another area of exposed metal could be the rails on the sides and rear of the turret? What about all the edges on the equipment on the turret top where they might get scuffed?
