Front Fender Issue
If there is a missing bolt, they are about $0.25 at the hardware store. If not push it in to place, hold it with a clamp, drill a small hole and pop rivet it together. If you have damage later, any body shop can drill out the aluminum rivet
I can assure you the fix will be far less obtrusive than the mismatched paint.
It will require some study and some "back time" on the pavement but it should be an easy fix.
I had the exact thing happen, but to my rear bumper. Gave it a couple of wacks with the flat of my hand and it popped right back in place and has stayed there ever since ( 6 months ago)
