Do not seal with wax as this deprived the SS of oxygen.
I had to look this one up. A basic or acid wax (most waxes) will break down the chromium oxide protective surface and prevent oxygen from reaching the surface so it can't create a new protective surface. So now it can eat away at the metal.
The next time somebody talks about waxing their rigging, I'm going to make them worry their mast falling down.
