yes @jtsanders @keith Gardner-Bender Ox-Gard in fact has zinc oxide, as suggested by its recommended usage.
also @keith nice explanation.
I am still uncertain whether to use zinc or aluminum anti-seize. Aluminum alloys appear all down the anodic series. I have an assumed aluminum mount and tranny (unknown specific alloy) with grade 10.9 bolts (unknown plating). The previous bolts were yellow something plated (Cadmium or Zinc…?), and had good amounts of red rust… so I think anti-seize is at least called for even though I never read about it with this Porsche 944, though I have read about this part seizing up on people.
here’s a bigger question - is there any grease that lacks a dielectric component? such that a grease would prohibit dielectric contact between metals. Dielectric grease I assume has dielectric in the medium, to allow charge transfer - but I think the grease component must exclude water - that’s how I explain dielectric grease keeping battery terminals healthy.
