You people make me feel old fashioned. I've painted hundreds of infantry & dozens of tanks for Warhammer 40k (37mm scale), but never used an air brush. Slap on a basecoat of white (since it makes details the most vivid) and do all the blending & feathering by hand.
What do y'all do for your weathering? Best results I ever got were using normally drywall spackle(sp?), mixing in brown paint, and using a toothbrush to splatter it on the tanks & transports. Then highlight with various shades of lighter browns once it dried. Worked really good, but anybody have any other clever techniques?
