6. Bonney and his team started with a 0.090-inch-thick sheet of 3003 aluminum from Industrial Metal Supply, which was cut to cover the central section of the engine bay. They used a bead roller to add some dimension to the largest part of the hood. Bonney used a hammer, a sandbag, and the tubing of the buggy to form the smooth curved front section of the hood. Finally the excess was trimmed off, giving it a perfectly formed nose.
