Its been awhile since I have done any dry brushing as part of the weathering on my wagons. The skill is know what colors will work best, in what sequence they should go and experimentation is also key I find.

I have a few timber topped flat cars and so using the dry brushing method seemed the best as I have more control over where the paint goes than when using an airbrush.

I started with using a dark brown and then followed with a series of lighter browns made mixing a very pale grey not white. This is because timber is more grey then any other color and timber will weather a very pale beige grey color unless like here on the flat cars where the timber is exposed to oils and rust from the loads they carry they will absorb those colors too.

Having done a general cover I went through and high-lighted several timbers in a beige white that is applied using a very small brush and thinned with white spirits. Depending on the look I'm after the thicker the paint will make some timber look newer than others. Having a good mix makes it look like the car's timber is repaired often which there are in real life.

Next job is to finish the weathering with the air brush.
