Tips on airbrushing plastic to look like wood

Last winter I did a Chevy Titan Dump Truck, Instead of the plastic Boards at the top of the dump bed, I used wooden coffee stirs. The are the perfect scale 2" x 6"

I realize that in some cases, cutting all the "plastic" wood out of a model isnt practical. I was hoping to do this to the Flatbed Semi Trailer, I want to get 2 Flat bed trailers and make them into one 53' trailer. Still I'm not sure how much work I'd get into on that.

Thanks

I've done it with both airbrush and regular brush.  Another trick I've seen is to apply a base coat, overcoat that with a slightly different wood color and then either sand through or rub through with rag and thinner. 

For the regular brush I drybrushed the second color. For airbrush I used a DA brush with thin paint and very light application.

This is better achieved by brush painting not airbrush. You'll find one such method here.
