Can Spraying German WWII Armor

Firstly, welcome to the forums! Well, it's always good to paint your own models for one. Do you have an airbrush? I would highly recomend using it if you do. The colors your going to want to use for the German Armor is a basecoat of a dark yellowish. Tamiya acrylics makes a color called "Dark Yellow" which was made specifically for german armor. Model master also made an acrylic called "Panzer yellow" or something like that too. Either works good, but if you were to handpaint the camo scheme, I'd recomend using model master's stuff. A good green color for the green in the camo scheme would be tamiya acyrlic "JA green". Model master makes a "panzer green" or "olive grun" or something relative to panzers that I would recomend to handbrush if you don't have an airbrush. Now for the brown I would recomend tamiya "red-brown" for the brown if you are going to airbrush it. For handpainting I would use model master "panzer brown". So what I'm saying is, tamiya is great for airbrushes, but gets kind of sticky after prolonged handpainting. But model master is useful for both-each company puts out an outstanding product.
I've heard of putting silly putty on parts of the tank and spraying it for the camo, then taking it off and doing the same for a different color. I wouldn't do that, you might want to stick with handpainting before that. Winter camo is hard to achieve with out an airbrush, but it is possible. Once you put on the winter wash on your tank without an airbrush, you pretty much can't touch it forever after that. This is because an airbrushless winter wash uses pastels that rub off on contact with the model.

Hope it helps!

Thanks for the help, Armor Master!

By way of follow-up, I painted my 1/25th Jagdpanther with Afrika tan (I think) and I'll be applying the stripey thingies today with the help of my girlfriend. The tank is monstrous.
She has an air compressor and knows how to paint.

Gotta love a helpful girlfriend
