Gorgeous! Those are stunning!
Hopefully I sent the "Care and feeding of your H290C Waveguide" document with the waveguide/horns. It mentions an option of painting with enamel to get a perfect finish. With the rest of the attention to detail in your speakers, you'll definitely want to take that step.
Lightly sand the face using 600 grit on a sanding block. Not much - just enough to remove the mold parting line. Don't sand any part of the flare, just sand the face. Then paint with spray enamel. You can take the waveguides to an auto paint shop if you want, but believe it or not, you can do a great job with a "rattle can" spray bottle.
