Well . . . I think that the factory got it right by reinforcing the panel
with plywood (if it were not needed I doubt that they would have done it),
but functionally 3mm aluminum (or even 1.5mm per Flight Crafters) sheet
would be equivalent. My concern with a flat panel of un-reinforced
epoxy-glass is that it would not be sufficiently rigid at 4 or 5 layers.

So would that mean 3MM aluminum is stonger and that 4 or 5 layers of flat
glass bid would not work for this aplication?
