Thanks everyone for the advice. Let me tell you a bit about this model.
ITs not my first model, its my first german tank. What i did was spray OD GREEN 2 from TAMIYA as the base coat and then I use DArk YELLOW from Mr Color. Overall i use MR COLOR MATT CLEAR COAT. And the green stripes i use Testor OD GREEN
I use to make camou from OD green and Black it was a warrior MCV from Academy, you can view it at my gallery.
AS for air spray, I can afford it, but i am worried this hobby will stop one day and i am left with a pile of tools. I have been making models since i was 9, but maybe due to my current job, i have some problems adjusting to the new time table. From a Platoon Sergeant in the Army to a Civillian Fire Fighter...what a contrast..
