I tried what you suggested, Charlie.....................but as it was my first attempt, it sure doesn't look as good as it may. I used weathering powders, Dullcote, rust washes, splattered actual mud, splattered dust paint, fogged on dust paint, and silver on the running boards and door window sills. I put rust on edges where it seemed appropriate. Put dust on the tire faces to make them look older as well. I am sure that I will get better at it, just takes time, repetition, and NERVES to mess up a perfectly good paint job! Thanks for the tips.........hope to see you at NNL this weekend and I WILL pick your brain!
