F82 M4 Wheel Arch Protective Film

Hi all -

I recently had someone open their door into my car and put a ding and scratch just above the rear wheel arch.

Just had that fixed through my Smart repair insurance, but to respray they had to remove the protective film panel (part 6 in this diagram https://shop.bmw.co.uk/7912/genuine-left-passenger... which I now want to replace.

Just wondering if anyone has replaced one of these before and can suggest best way to go about it.

Is it an easy DIY? I'm mindful that if I try it myself, I might up with a load of bubbles or sticking it in the wrong place

TIA
