As i had to think way to make lighter front fuselage mold, bottom fin was perfect test subject.
Mold was machined to urethane foam, which was then glassed and glass painted with special polyester coating material.
Then mold was machined once again. As a final touch, mold was painted and buffed.


Bottom fin, once again untrimmed. I hate carbon dust and i trim parts only when it is absolutely necessity.

Hmmm.... Mach 2
