Clear protective film?

Is there a preferred clear protective film you guys use, if you use it at all? There are just a few key spots I wanted to protect but wasn't sure which film to go with.

 

Ceramic Pro Kavaka or Suntek. 12 yr manufacturers warranty if I remover correctly. While it’s not on my truck, the shop I deal with installs this on high end cars, Ferrari, McClaren, Aston Martin they are a very high end shop.

 

I just use the genuine 3m material. Can buy petty much any size you want on ebay or Amazon. I buy a 6" or 12" wide roll that is about five feet long and just cut pieces as I need it.
