Fiberglass Hoods and Body Panels

The underside of your hood will depend on a couple factors. One being the weight. If the hood is a race trim hood, it will be lighter, flimsy and not much care taken to what the underside of the hood looks like. The other (nicer) way to do either a fiberglass or carbon fiber hood would be to actually make two castings. One of the outer surface, and the other of the underside. This will leave a gel coated surface on both the outside and inside surface. Then the two molds are trimmed and glassed together.
