Galvanized steel doesn't mean it's mixed into the steel. If that area's been damaged in any way by the jack and you see dark grey or red (exposed steel or rusted steel) or if you're just worried you can buy some zinc-rich paint and spray the area. You'll need to clean the area with a wire brush and then spray on. Make sure you mask the area appropriately (I like to use two layers of white garbage bags and painters tape when doing any paint work on my cars).
As an aside, this is the same method we use for repairing bridge structures if the galvanizing is ever damaged or questionable and exposed.
