I work in the paint industry, and one of the companies I work with makes a chrome paint, but it's not an automotive type of paint. It's an interior 2-component alkyd varnish.. I've requested a sample, don't know anything more about it at this time. The rep told me that if the surface is prepped good and flat, it looks pretty good, but he was unsure of how much yellowing it would see if exposed to extended UV.
