Door panel refurbishment

I am in the process of detailing my Twizy before its MOT next week.

I am planning on taking a orbital polisher to the lower see through section of the doors.

Do we know what material they are?
Poly carbonate ? Acrylic ?

This confirms the front deflectors are poly-c so maybe the whole car is?

I am treating it like a headlight restoration and just going to use compound paste 3000grit or maybe 2000grit.

Any thoughts?
Might be something useful in there.
