Fiberglass pans

[vdubzack]

Installing the pans will both take about the same amount of time so I would go Metal. No chance of delamination of the layup. Out gassing of the resins Stress cracks, and so on. Most fiberglass floors are secured with bonding resin and sheet metal screws, (at least thats what the manufacturer suggested )Which gives a stress point at each screw hole. New metal finishing materials and rust proofing materials are state of the art and should give you years of service. At least you will know when a metal floor needs attention, Not too sure on the fiberglass.
