Thanks Tojo!
I don't build armor or ground vehicles so am clueless as to how to weather them, one thing I have in my favor is where I live...there are lots of off road trucks here and I got the idea for weathering my jeep from looking at how the mud and dirt looks on the full size vehicles.
I am also building a 1/32 scale Fw 190 and this one also has some dirt and mud splatters on it, doing this type of weathering is fun and may inspire me to try an armor model in the future.
