A base sheet of transparent polycarbonate material has a formed shape
including a center portion and a peripheral portion. The center portion
is formed by a non-contact forming operation occurring at a temperature
above the glass transition temperature and below the melt temperature of
the transparent polycarbonate material, thereby resulting in the center
portion of the base sheet being free of visual distortion. A top coat
layer is disposed over the base sheet. The top coat layer has a greater
resistance to abrasion than the polycarbonate material and provides UV
protection to the base sheet. A primer coating is disposed between the
base sheet and the top coat layer to facilitate bonding therebetween. The
peripheral portion can have a shape created by a contact forming
operation occurring at a temperature above the glass transition
temperature and below the melt temperature of the polycarbonate material.
