Had a hot dip galv plant in one factory, but that was a lot of years ago and my personal involvement wasnt huge. As I remember it, dipping steel in molten zinc allows a zinc / iron alloy to form at the interface with a zinc coating on the surface. The thickness of this coating varies - you only need to buy some spun galv 3rd world shackles to know how thin it can be made.
They say that zinguard is as effective as some hot dip so presumably they can give you tech data to confirm this. For myself I cant see it being as effective as hot dipping to BS. How would you ever get a cold applied zinc film as thick and its film thickness that causes a sacrificial coating to last. However, to me the issue is also that if you now paint / coat, you will likely have a problem preparing the anchor to be hot dipped in the future. This has to be removed before hot dipping and preparation can be more expensive than the dipping itself.
