Congrats and welcome to the forum.
Keep us posted on how your early weeks and months of ownership go since this being a new car there still a lot of questions and skepticism around it. But its an Infiniti, so there's a healthy level of confidence around it.
Ahh I've never heard about the Tribos paint treatment so I'll have to check that out. I never typically trust anything on the wheels (in the sense of you don't need to scrub em') so I always address the wheels the same way all the time lol
Yeah, it's always good to have some sort of protection on there just to make life easier in the whole. Of course it'll never make anything magically spray water on and clean, but it helps tremendously especially with rim discoloration over time.
