drybrushing airplanes

The technique of drybrush serves to give to the model the aspect of used, aged and basically it consists of giving to the model through clearer tonalities the used aspect.The technique consists of wetting a flat brush in an ink of tonality clearer than of the final painting, drying it in a piece of paper or cloth and to pass on the parts that present accented use, and mainly high relives.But well-taken care of not to exaggerate or its model it goes to seem made of rock. You must make tests before in old kits, and has in mind that the experience and the persistence will only bring you excellent results.

Joao, have a look in the techniques part of the forum for advice on how to dry brush. In 1/72 it would be very easy to overdo the effect, so just a little is enough.
Put it where the aircraft would get dirty, cannon ports and shell case chutes, maybe the rear of the engines from leaks, mud splashed up from wheels, and underneath, just back from the leading edge of the wing, I would sugest a light grey to contrast with the black. The 262's had quite short lives from new, so would not have gotten too dirty.
