I think this is going to come around to how much driving are you going to do.
If it is wonderful and looks great, you will have a problem with driving it too many places as...you will get rock, junk and crud thrown at the car.
I have Rhino hide covering the bottom part of the car's body. Would I do it again, YES. My car is driven a lot in the summer. The Rhino hide doesn't look smooth and finshed as much as it protects the surface from abuse.
So, if you coat with a "bed liner" it may not look as nice as a finished inner fender.
Just my $0.03
