I have these hiking shoes that have metal hook type of eyelets. Since I frequently go to the leech infested areas of the western ghats in India, I'm forced to use salt on my shoes to prevent leeches from climbing onto me (and it works pretty well). But due to salt, the metal hooks seem to be rusting.
Is there a way I can prevent the rust while still exposing the hooks to salt? This post talks about using oil as a possible solution to prevent rusting. But obviously with shoes it would be impossible to do. I'm thinking if there is a chemical coating that could help me with this.
