I am by no means authority, but it is my understanding that the transmission case is magnesium. based on that assumption cleaning it with whatever not corrosive means is fine, but once that is done, it needs to be painted or otherwise coated. mag oxidises and becomes brittle in no time if not protected from the atmosphere. on my matchless g50 the cases and hubs were mag and had an aluminized gold paint that was on any of the magnesium parts. it used to turn green overnight without a barrier.

I would guess it is more of a east coast thing because of the salt on the roads!

I have not had any problems here in central california!
