The raised bead on the inner panels is a nice touch, and it adds a bunch of strength to the panel. Are you planning to spray them chassis black, or another color?
You know you're hosed now, right? Once you put one custom panel like that under the hood, you are now committed to having to do the entire engine compartment (including the under-side of the hood). Kinda like steel braided hose.....if you put one piece in, you have to do 'em all the same.
