3. Once the hood is in its proper bolted-in location, begin the prep work for the paint. Check the fiberglass hood closely for imperfections, chips, gouges or high/low spots that will need to be fixed. Our hood's surface was in fairly good condition, but it had a few chips from shipping. Many people opt to paint only the top side of the hood to cut costs, but we wanted our entire hood to have body color. So, the underside of our fiberglass hood needed to be smoothed so that the final product would look nice. Here (photo), the extra fiberglass gunk from manufacturing needs to be sanded and smoothed during the "prep work" stage.
