How do you guys do washes and drybrushing for a tank with a camoflage scheme?? I always seem to end up losing the camoflage scheme after washing and highlighting the details............

I wash with black or dark brown. This is not usually applied to everything, but to those palce I want to increase shadows and definition, i.e., along panel lines, bolts and other raised detain and grilles. For drubrushing, depending on how extensive each color is, I'll either drybrush each color with llightened shades of the color or if the pattern is very complex or hax fine llines, I'll chose the base color, since the other colors would have been appied over that most of the time. However, if the base color has been extensively overcoated on the prototype, such as some German WWII had far more green than the original yellow, I'll go with the dominent color.

If you ar losing your pattern from these processes, your are using too much paint in them. Washes and drybrushing must be very subtle. (:-)
