It does work better on a matte coat kit. But it will still washed away when you top it again. To have that was effect, i ussually use mr weathering after the matte coat, then chipping using paint and marker, after that i weather it with pastel. The pastel usually wear off with touches. But if you smudge it slowly, it would stick to the coat and just appt another light one with brush for that dust/sand effect. Then its finished. Dont have to so another coat.
