Has anyone tried using navy wax on black shell? The hanger project claims the same logic as a midnight blue tuxedo...makes the black look more black in low light. The site also claims it gives the black a bit of depth in normal light. I have black and navy tuxedos and much prefer the navy as it looks richer at night, so I'm hoping there's some truth to the claim. If no one has experience with this I'll post some before and afters once I try it.
I will let you know about it on black shell in a few weeks when my black shell captoes arrive, I ordered them just for that purpose although for wear with Navy suits not a tux. I posted about using Saphir Navy Blue #6 wax on black calf a couple of weeks ago here.
If one of my men showed up with blue polish on his shoes for a general inspection I would fail him for being out of uniform. But for special details like colors or burial detail as long as every man did it I was OK with it, even preferred it. In bright light like the tropics or some sandbox somewhere the shoe looks like it is layered with alternating colors of black and blue. In fact for the first 10 years or so I thought that was how it was done. But it is just 2-3 coats of blue on top of black. And inside in 60 cycle sunlight it does somehow look more black but also still has depth. It is hard to get pictures to capture it accurately. In the end it is well worth it IMO.
