Fuselage paint

I am trying to repaint the basic white on the fuselage of a repaint kit. I am trying to make it more opaque. I use the magic wand tool but it will not highlight the hole tail section. Certain areas in the tail are exclude. It apppears that it exluding darker areas of the of the tail section (shadow effect?) I have adjusted the tolerence to sveral different setting. But it just wont high light the hole tail section. Any help/tips on this would be appreciated.
It might be that I have to do this with the freehand tool
