While we're talking about it. Here's the reverse of the bezels.
Original. The factory had flat black painted into very specific locations.
I do not know how important the off-white color is and how that plays into the diffusion of the light into the gauges.
It seems important enough that the metal lens holders are painted the same color.

Hence my comment about if I did it again, I would remove and install the lenses myself.

One possibility I'm looking at is to mask and spray with an airbrush using SEM Color Coat. This is not my area of knowledge or experience so it will depend on what I can buy and get help with locally. But the folks at Vacu-ornametal said that particular line of paint will adhere to the chrome, so that seems like the best way paint to use.
