Looks great, what is your technique?
I used Floquil rust and grime. Get paint brush almost dry then dab on the paint . Then with a wide brush dipped in thinner as a wash blend it in.
The best thing is to experiment on a relatively cheap car, either Athearn blue box or Atlas trainman and then experiment. I also used a rag dipped in thinner for some of the streaking. I then went back with an airbrush to get a dirty underbody look with grime.
