Hi U4ic,
Knarr here. I had a Paint Protection Film or Clear Bra applied within a couple of months of taking delivery. Had full hood, front, front fenders and mirrors done. If you decide on this amount of coverage, plan on spending between $1,200 and $1,600. A lot will depend on the shop and brand of PPF. It feels great to have PPF. No worries when it comes to certain types of road debris. The modern versions of PPF are "self healing". So far I have not seen this attribute in action. It also resists fading which is nice. The cost might seem a bit expensive but there is peace of mind when I'm on the freeway dealing with trucks kicking up dirt and funk.
Your second question has to do with window tint that employs ceramic. I can't help you out there. I went with a mid range, standard tint at 26%. Same as the factory tinted windows.
I hope this is helpful and things work out to your satisfaction.
