Not my pics haha, I probably should've made that clear.
The deadener is fine, he applied it to the flat surfaces because the curved areas are already resistant to vibrations. You could always shoot for 100% (or near 100%) coverage but it doesn't do you much good.
most of those places are a waste of deadener and time. . sealing off the door is where its at, and concentrating behind the driver and around it.
Hmmm...I see what you mean now. I wouldn't want to seal a door with deadener (not to say that that's what you meant, you seem pretty smart lol) because you'd have hell if something went wrong inside the door. But hey you gotta start somewhere right?
EDIT: Separating the front waves from back waves will net you the greatest improvement in sound. I'm sure you know that but I'm agreeing.
