Not really, now that you mention it, makes sense about the grill. I thought about PPF on the front, but then thought, naw, I'll just get my neighbor to re-spray .the bumper in 5 or 10 years, if it bugs me. (he's an amazing auto body guy). And I love how easy it is to clean off the nose, compared to a grille.
I am fixing the chips in more obvious places, up on the hood and the rear hatch.
I like stuff to show wear, up to a point. More comfortable to live with, don't worry as much, and the patina is a reminder of the history we've had with it. I guess it will be a curated patina, anything that could rust or corrode will get fixed.
