A wood buck is made with the desired shape of the scoop.
Rigid urethane foam board is stacked up in layers. Each layer is hot glued in spots to keep it in place.
The foam is then carved to match the buck. Corners are radiused to match the existing front piece.
Once the foam is the desired shape it is covered with cellophane tape and has a mold release applied. This allows the foam to be removed easily after the fiberglass is cured.
This photo shows the fiberglass layed out over the foam form. Once this is cured the back end of the hood scoop can be finished with fiberglass as well.
The scoop has now been bonded to the mounting flange as well as a skim coat of filler has been applied and sanded to smooth out the fiberglass. Next task is to trim out the mounting flange and drill holes for dzus fasteners.
After the body has been fitted the car is disassembled and the frame is sandblasted and painted.
The body color is called vapor silver. Only one coat of clear is applied at this stage, enough to protect the base color while taping out the flames.
Once the body and all panels are installed back on the chassis the flames can be taped out. This car has fairly flat sides and thus allows for another way of taping out the flames. Using a computer, the picture below was placed in Adobe Illustrator and the flames were drawn over top the image. Once the the design was completed the file was transfered to a laptop computer and projected on the car with a video projector. With most of the lights off the projected image is very clear and it is easy to follow the lines with tape. Once the first side is completed, simply flip the computer image left to right and project it on the other side. This technique makes it very easy to duplicate the design on both sides of the car.
This photo looks like the car has lots of shaving cuts. The small pieces of masking tape are indicators which areas are to be masked. Once the panels are removed it is sometimes confusing which areas are to be masked and which are not. Having the tape indicators eliminates this confusion.
Masked and ready for paint.
