I had given thought to using factory underhood frame. Getting hard to find a hood that isn't twisted or so far away that the freight costs more than the hood. I like the ability to have the factory hinge. At a quick glance the factory hinge would make the hood look stock. Structurally speaking, aluminum tubing stronger than solid wood of the same dimensions? Since aluminum oxidizes quickly, do you scuff then clean and epoxy for the best results?
