I've heard people accused of "gold-plating" their projects, but this is the

I've seen mention of gold-plating cooling passages before, in one or two
papers on hydrocarbon coking, as protection against corrosion of copper by
sulfur impurities. There are several possible plating metals, but gold is
the best match for copper's properties, and the technology for plating
very thin layers of it on copper was perfected long ago for circuit-board
edge connectors.
