Kev, Ralph has made a good suggestion, I would try plain white chalk dust too if you aren't comfortable with rattle cans. You need to add some very light gray (rattle can primer)or flat white to "oxidize" the black. I have used flat white paint from the dollar general but that makes a permanent change that you may not like. I have laid the object with the surface to weather upright and sprayed the area about 18 inches above and let the spray fall on the surface. Once I got the desired results I used dull coat to keep it there as the paint is mostly dust when it reaches the surface. try painting a piece of something gloss black first to use to test this if you aren't comfortable working with the models first.
I think this is the look you want.
