Underbody best finish

I have nearly got the duster floor pan to bare metal, absolut mission as someone sprayed sound deadner and wire wheel struggled with it.
So the question is how should i finish the floor:
-Chassis black
-Sound deadner like Worth etc
-Raptor liner tinted black (My panel beater suggested this as hard wearing and doesnt chip etc also good for inside the wheel wells etc

I will sound deaden the whole floor pan from above as well as dynamat and a thick carpet underlay with a heat shield in it. Made huge diference in my other project cars
