Hemp in the Fast Lane Continued, part 2 of 4...
With the solid mock-up frame, it is now time to make the hemp cored fiberglass body.
Clay is used to separate the areas of the car as seams. This is done to get separate pieces that will fit together after completion. If using a singular body, this step can be skipped.
After a light dusting of powder on the mock-up surface, a thin layer of fiberglass plaster is applied to about 1/8 to 1/4 inch thick.

While the first thin layer of plaster is still wet, the core of the car body is placed. The core holding the whole project together is made of Hemp!
Taking cut pieces of hemp cloth, the hemp is dipped into and soaked in the fiberglass plaster. The saturated hemp is then laid in a single layer on the still wet mock-up. This second layer will act like a core holding the fiberglass body together.

Next the final layer of fiberglass plaster is added on top of the hemp core. This is a rough layer making sure to have the depth needed for the mold.

Cutting, scraping and sanding, the hemp cored fiberglass body is now shaped into its final form. After drying the mold is removed from the mock-up body.
