Well I guess I broke all the rules after reading this thread! My hood is cut out and my scoop was riveted on when I set it in fiberglass putty, but I did grind off the rivet heads after it had set up. I laid fiberglass cloth over the top, then body filler to level everything out. I did this in September 2015 and it still looks good today. Worth noting that I did brace up the edges of the hood after cutting out the opening. I also used the metal I cut out of the hood to brace up the hood scoop and incorporated a support brace in the center of the scoop to cut down on the flexing from the wind.
