So apparently, this 1996 iteration "mystic" color was very "controversial", expensive and rare because the dye was also used by the federal reserves for the anti-counterfeiting technology at that time, making it a controlled substance.
A Ford rep would have to deliver the paint to an approved body shop, supervise the usage to ensure it was used properly, then re-seal the can and return the unused portion.
The Mystichrome in 2004 was reformulated.
