The zincpest and dezink doesn´t really scare me much, especially on something like this, with every part needed being available from the manufacturer

Only theorizing with my restricted personal experience here, my firm belief is that it doesn´t really do diddly gluing them up...unless there´s some broken off part one wants to glue back on there.

I have kept 2 heavily damaged Mazak parts here for about a decade, done absolutely nothing to them, besides checking on their condition once every other year, and they haven´t changed at all since they entered here.

What i believe is that this is a simple chemical reaction, formed by two or more incompatible metals, which uses humidity/moisture as a catalyst, to expand and thereby break the material to pieces.
It is highly unlikely that this is an undiscovered perpetual motion formula, so if left in a dry environment, or when the chemical process has completed, there´s no more fuel left, and the deterioration will stop.

One could argue that glue will seal out any incoming moisture or humidity in the air, but so will a layer of paint or a clearcoat.
As long as the part is completely dried out before coating, that would most likely work to some extent.
