Nissan 370Z Forum - New 370z owner in Middle TN

Hey everyone! My name's Zach and I just picked up my 2013 370Z MB 6MT a couple of days ago and so far I love it. I just recently moved to Nashville after graduating for work which allowed me, financially, to buy my first brand new car (and I think I made a very good choice). I'm excited to be a part of the forums here because this is my first Nissan so I'm eager to learn everything I can about the car which brings me to my first question. One thing I've noticed throughout owning all of the vehicles that I've had is that the bottoms of the interior door panels get scratched relatively easily when passengers enter and exit the car and bump it with their feet. This especially shows up on the black plastic and after two days there's already a couple of scuffs that I've been able to wipe off. However, to avoid any potential future scratches/scuffs, does anyone have any ideas on what I could use to protect the bottom of the door panels?
