Substitute Surface Material for Kickers & Sliders

Other than Trek and PVC Sheeting has anyone used any other substitute material for kickers and sliders?
I have 3- substitutes I was hoping some of you guys may have tried out and get your opinions on.
- FRP
- Shower Wall Material
- Poly-something?? - has a bit texture to it.

I used some Agro vinyl strips. Quite a durable and cost effective alternative, if you ask me.
