Thank you Alan! I saw a tutorial someone posted on the "salt technique" and tried it. My method was a coat of red oxide primer. When that dried, sprayed it with water and sprinkled salt all over the wet surface, lightly in some areas and in clumps in others. Then sprayed it again with a light coat of darker brown primer, and white, almost in a camo style, but feathered edges. Once that was about dry (not quite), I took a toothbrush to it and started brushing off the salt and top coat. Hand rubbed that. Then used some acrylic washes in blues, greens and browns, watered down and with a paint brush. Some chalk pastels in rust colors here and there... in a couple of places I heated the body and pressed a jagged rock into it when still soft to create some dents. I really enjoy the process of weathering a car. I figure man made the car - God made the weathering! I'm trying to recreate what nature has done.
