DIY door panel

I was talking to the local upholsterer, there are plastic sheets used instead of wood fibre.
Im thinking i will try it.
I cut 60's Lincoln 4 door convertible door panels out from .093 ABS plastic for my boss when he re-does the door panels (also making the seat back panels to recover also) they turn out pretty good,are weather proof don't break when you pull out the clips and just look better for durability.
here is a simulation of the panels that I have to cut from ABS 61-3.jpg
