During my ownership the car was stored in a dry de-humidified garage under a indoor cover. After two outings when it might have picked up salty deposits, the entire underneath was thoroughly cleaned as well as the bodywork. I fear that it was the original application that was inadequate and Toni realises it.
It is a good thing that Toni and I are the best of friends and this scenario has increased the friendship and trust between us.

(edit) my bad I didn't realise you bought the car back so probably dont know how it was stored.
