You can either spray it over the entire area, or you can do it in specific areas. I did it in specific areas when I was doing my gauntlets. It really all depends on how weathered you want it to look when you are deciding how dark to make it. I think it is best to go light because you can always go back and darken it up. Just make sure that you get water mixed into the acrylic, and it is usually best when you get to the bottom of the bottle of the paint to put some water in the bottle and mix it up or else you could get a clog in your airbrush.
