The paint was pretty basic. I just bought a 10 pack of cheap brushes from the dollar store and used brown, flat black and flat tan on the pretty dry brushes. Once I got a little paint on the brush I would get rid of most of it on a envelope and then lightly brushed the color on. To bend/warp the parts I just used a bic lighter to soften the plastic. I even used a wide brush on the body color and made sure it was pretty thick since I wasn't worried about perfect paint and it left little lumps and bumps for the dirt paint to catch on.
It was actually a good thing I decided to go with barn find on this one. One of the dogs got hold of the front fender fillers and one of the fender scoops and chewed them up pretty good after I'd already decided to make it a junker.
As I get more colors to work with I'll probably come up with some different dirt schemes.
I had a bunch of old models in Canaduh that I tossed out when I was up there a couple of months ago, now I kind of wish I hadn't.
