Welcome to the board, mate. Thanks for sharing the subtle, simple project. Sometimes, it's the little projects that we find most rewarding.
Looks great. I did this with a couple grilles. I had a shitty, chrome one which was missing most of the chrome. Hit it with flat black. The paint only began flaking off when I used the grille (and, indeed, the entire front of the car) to bend a Kia in half at the B-pillar. Fortunately, the replacement grille was white plastic, which I simply re-sprayed flat black. A fun little project.
