"gas tank" style controller housing

Inspired by aussiejesters fiberglass battery box I decided to make a controller housing using the same technique. By the way, that guys work is crescent fresh. Take some time to check out his trike video on youtube with the same screen name.

Originally I was just shaping this piece as a mock up to use as a guide to make the housing out of wood. But I'm starting to think that wood might be too vulnerable to the elements and cause heat build ups. Not that the solid wood idea is totally out the window but the fiberglass option just keeps looking better. I'm shopping around for a large styrofoam block to shape the final piece out of at the moment.
