I bonded a 5inch-high fiberglass cowl induction scoop to the factory steel hood.

First, I cut out as much steel as I could with the plasma cutter, because I'm always trying to reduce weight from the car.
There isnt much left of this thing. (Later on, I removed the center hood reinforcement visible in the pic, too)
I also rough ground the area where I planned to apply the fiberglass cloth and resin. (The polyester resin adheres nicely to roughly ground steel.)

Test fitting, measuring for center and drilling rivet holes about every 2 inches around the scoop and into the hood.

The only modification required on the scoop was to trim a small notch to clear the factory hood center bump.


I laid down a strip of fiberglass cloth under the edge of the scoop, all the way around, and fully saturated the cloth with polyester resin. I then carefully laid the scoop down on the wet cloth and installed all the rivets in the previously drilled holes. I made sure to keep the riveting process tight, so the scoop lay flat against the hood on all edges. Resin squeezed out from underneath, so I know it's a water-tight seal.
Although not shown in the pics, I then laid another strip of saturated fiberglass cloth over the top of the riveted areas, and overlapped it onto the steel hood about 2 inches.

I used fiberglass-reinforced body filler (A.K.A. "Tiger Hair") as a base to cover the fiberglass cloth, because it's far stronger than regular body filler and less likely to crack.
I also used the Tiger Hair to build up and blend the area around the factory center bump, so that it flows smoothly into the bump on the scoop. (I like the look of that center bump)
I then finished the body work with standard plastic filler and "Icing", which is a very light filler. The picture shows the nearly-finished hood with a coat of gray epoxy-primer. (why gray you ask? It's what happened to be laying around the shop)
