I was reading the details at the link, these 2 are not actually "gold", they are Titanium Nitride (TiN ) which, while still looking like something a New Orleans pimp would carry at least has the advantage of being a wear resistance coating used on cutting tools that could actually be useful on INTERNAL parts, and frame rails. As far as using it for a finish, well, a solid even coat looks better than "tiger stripe" or 2tone, but it still looks like something that would be owned by a pimp, or 3rd world dictator.
