Making a headliner

I thought I would update yall, before I start on the cage, it occurred to me that fabbing the head liner would be easier without the cage in the way.
The white material is called High Impact Poly Styrene, and is the same plastic Styrofoam is made out of. It is heat formable and epoxy sticks to it. now that Ive gotten it this far Ill take it back in the shop to fine tune it and bag a layer of carbon to it for future installation.
