also Lexan scratches if you look at it wrong, not a good plastic for making a tank out of at all. that is why they sandwich it between acrylic to make bullet proof skylights and windows ( I built the ones on the cop shop in Edmonton) that way it can have the scratch resistance of the acrylic for cleaning and the strength of the polycarbonate.
