My 2012 doesn't seem to have such sticker as well.

 

Yeah I've yet to see the label on any 2012's, no idea why but my guess is the supplier is still down or out of business or they chose to drop it.

 

But the paint seems to be self-healing. I have a few swirl mark on the door as I rubbed a little too hard to remove some sticky residual. But most disappeared after a few days when I looked at it again!

 

My early 2010 Black Obsidian says hard clearcoat under the hood, and no post - 2009 Infiniti TSBs list self healing paint anywhere, so aside from common forum speculation, I have not found any evidence that self healing scratch guard paint was used on any model year outside of 2009 on Infiniti vehicles. This may give some answers:
