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, dla.mil] trivalent conversion coating and then painted with epoxy or some other paint for equivalent performance. Good luck.
