Tryin to decide whether i want to use aluminum or steel pans for the floor/wheel tubs'rear firewall/interior/etc in my car.

I know the aluminum will be a bit lighter but anyone know if the wieght difference is really that much?

Also i've heard guys say the aluminum tubs dent alot easier for a car that is see "limited" street use will they dent easily enough to make the tubs look "bad" quickly?

I really like the looks of the aluminum but dont want to use them if they are gonna dent up fast.
