Just got my first 3rd gen!

I love it, but it's from a 2-tag state, and I couldnt stand leaving the tag bracket on it and decided to live with the 3 holes.



Is there any kind of filler I can use for this? I figure it's a small piece, so filling, sanding, etc wouldn't be too too much trouble, but since it's plastic, I dont know if I'd be better off just getting a new grille. It just seems like a shame to waste it.

But I figured I'd run it through here first, not really sure whether this is body or detailing,
