It sort of went crappy and flaky within a few months. I wouldn't use it on any galvanised items.

I doubt the galv reacted with the lanolin- but you could very well have sealed something in under the lanolin that caused the reaction (zinc is one of the most reactive metals hence it's use for cathodic coating and protection of less reactive metals).
