Go for the fibreglass.
It's lighter but i don't think there's a big weight difference between alu and fibreglass.

Ali would be lighter if you make it thin enougth. I used 1mm thick ali. It is a lot more effort though and easy to make it look crap.
I used ali 'cos it was cheeper for me and it was lighter. My MK indy Blackbird weighs only 370Kg in Road trim and a lot less if i take out
passenger seat/ remove lights etc.

Fibreglass is about 25% lighter in trme of density but generally made thicker to be stable, i.e if if a typical glass panel is 2mm thick then a 1.2mm
ali panel will be lighter.
In addition the ali will contribute some effect to chassis stiffness, the glass will not.
So my answer is ALI.

What condition was the car in when weighed, as seabass suggests that it amazingly light.

Aluminium alloy will win hands down. As said earlier fibre glass is made thicker to achieve rigidity and as such comes in heavier. Stainless steel is
heavier but can be used in thinner gauges, (my choice). If you are not intending the panels to contribute to the rigidity of the car then alloy of .5
or .7mm will be more than sufficient. Be aware though that you would not be able to mount components directly to the alloy in these gauges as it would
rapidly age harden and crack.
