Seeking gold zinc dichromate spray source

Any luck outside of this blog? I'm in need of the same.

Hi, Bill. There may be some semantic issues with Todd's request. Are you looking for paint -- a zinc dichromate spray paint? I believe this may be unavailable anymore due to the fact that dichromate (hexavalent chromium) is toxic and carcinogenic. If the components are aluminum, they can be pretreated in a Mil-DTL-5541 [link is to free spec at Defense Logistics Agency,] trivalent conversion coating and then painted with epoxy or some other paint for equivalent performance. Good luck.
