I've never done fiber-glassing but I've seen a lot of step-by-step tutorials. What I have seen is building a frame and stretching fleece over the frame. But this won't work for my application. I am trying to sqeeze as much air space as possible out the cubbyhole behind the wheel well of my car. How would I go about creating a mold to snugly fit into that space?
(I will be using MDF for a front, and top plate, but everything elsewill be glassed to fit the space).
