Besides being bulletproof,  a good reason for using polycarbonate is that it is 
much more flexible than acrylic.  You do not have to force it, it will almost 
noodle its way to fit on the curved surface.   The drawback of using 
polycarbonate: cost, UV degradation, and surface scratching, are less of an 
issue these days.  Bayer makes an extended abrasion and UV resistance 
polycarbonate called  Makrolon 15.  A piece of 1/4" x 10" x 43" transparent 
grey goes for $35 at EStreetPlastics.com <http://estreetplastics.com/>.
