Front grille color / paint recommendation

[auditechnik]

Hi all, I just added a 2018 B9 Audi A4 2.0T Premium Plus ultra S-line to my collection (shown in photo).

I removed the front license plate and its mounting bracket. It resulted in a visible trough & screw holes on the front grille. So I ordered the Audi OE cover (part# 8W0 807 287 B RU6) which hides the trough and provide a flat surface.

The cover fits perfectly, but is black in color, whereas the grille section (between the horizontal chrome trims) is a matte dark metallic grey, so there’s a mismatch. I would like to paint the cover to match.

I don’t know what’s the correct paint color to use. Can someone here point me to an appropriate paint product? I’d like to use spray paint in an aerosol can for an even & consistent finish.

Thanks in advance.
