[Christ]

You can just wax the hood... or tape aluminum foil to it before you lay the fiber down. As far as the bottom of the hood, you don't need all that ribbing under there... you can get away with a basic framework, which will save weight.

With glass, it's weight comes from the amount of resin you use, and the type... the more unnecessary work you put into it, the more resin you have to use, and the more weight you end up with.
