This is a little off topic but I will ask anyway. I'am helping a friend's son with his pickup truck. He has made a "flush with the rails" Tonneau cover for the bed of his fancy pickup. He used aluminum channel around the primeter of the box and used lauan ply to slide into the channel, the underside is reenforced with joists. He wants to cover the plywood with glass- epoxy (my idea) and paint it the same color as the truck(orange) or black

The question is: will the sun get the dark colored epoxied-glassed plywood too hot and destroy the epoxy? Are there any pigments that will color the epoxy that look as good as paint? and finally will the epoxy need to have UV protection if a pigment is used instead of paint?

Thanks,

Larry C.
