Mocking Up Parts    
Start out by drawing with a grease pencil where the scoops will go.

    Rich tip:  Before proceeding, it is important to stress wearing proper gloves. It can really mess you up if you get these toxic materials on your hands and then rub your eyes or other sensitive areas. I always use MicroFlex diamond grip gloves which, in my opinion, are the best quality gloves in the business.

In a little work area we created for the purpose, the hood was splashed by laying down a sheet of 3 oz. matting and coating it with resin, mixed with 2% catalyst. Make sure the resin completely saturates the matting. Now add a second piece of matting on top, giving six total ounces of fiberglass matting.
Rich tip: The fenders were taped over with masking tape for the eventual over hang from the splashing.

We continued to saturate, flipping the piece over to saturate through the other side. Next we laid this matting on top of the hood and formed it with our hands

    Rich tip:  Squeeze all the air bubbles out of the matting. The easiest way is by using a fiberglass roller.

After splashing the hood, we mocked up foam pieces previously cut roughly to size and drew contour lines to follow the shape of the hood. Next the pieces were attached to the hood with bondo. We continued by drawing more contour lines and reference markings for shaping.

The concept drawing was always nearby to keep us on track sticking to our original design. To shape the foam faster, a cheese grater was used for the rougher cuts, then sanding blocks with 36 grit sand paper were used for fine tuning.

Now seal up the foam plug with 3 oz. fiberglass matting. It should look like a mummy. From here, we used bondo and did our usual body finishing techniques (see Custom Corner at www.autobodynews.com). The only difference is that going by our reference markings on the foam, we used different colored hardeners with the bondo; that way it was evident when to stop sanding when we sanded through one layer of bondo and got to the next color. This facilitated keeping the finish looking even while we mirrored our other sides. Finally, we finished off our plugs with sealer, primer, and then polished them up with 600 wet sandpaper.
