I had one one in my 2019 IS and it does protect the paintwork but of course the protector itself gets scratched and one scratch on mine stood out to me. Doubt others saw it but I did every time. Trouble is my car has to serve as my daily transport which also includes occasional trips to the recycling centre, holidays, golf course duty (clubs and trolley in and out of the boot), trips to the diy store, etc. I don’t have one on my NX and I’m really trying to be a bit less bothered about the odd scratch and scuff that inevitably happen during said use.
