Hello skeata,
I paint the model first with silver. for the spots I take maskol Humbrol on a sponge and dab it on the silver surface. Then comes the camouflage on it. After drying allows the Maskolpunkte rubbed off with your finger. Gives a nice effect if you do not overdo it.
Have fun while trying it

Thank Christian , I must admit it looks more like flack damage than wear ! I painted with silver and then added wet salt , also tried chalk powder and water seemed to have the same result .after drying of course
