Petroleum vapor compatibility of zinc alloy plating

We use acid zn plated mild steel components about 8 - 15 micron plating thickness. These get rusted. The are exposed the petroleum vapour (hardly petroleum oil directly). I wish to know to avoid rusting, which plting will be more effective and resistive to petroleum vapour and outdoor environment. That is, which plating cobalt zn / cyanide zn / acid zn you recommend and what should be thickness.

Thanks and regards.

If the Sulfur levels are high Zinc or its named alloys may not help , though Cobalt Zinc is possibly the only alloy that may last a bit longer.

The one solution is Zinc Tin alloy which is in use in the automotive field for similar applications.
