Element Grounding

Okay, I pulled out my Ohmeter and took a few readings on my pot.

Across the wire, from end of the ground to the ground itself: 0.5Ω.
From end of wire to pot: 1.5Ω.
From end of wire to skirt on element: 0.6Ω.
From ground to positive lead: 13MΩ.
From ground to negative lead: 13MΩ.
From ground to neutral: 0Ω. (which is correct, since the neutral is not connected to anything).

Other than the fact that the 13MΩ implies the circuit to the leads is being completed, which isn't ideal when there is no water in it :\ (I think)... it seems I am within reasonable tolerances for resistance across the various boundaries. This should mean that the inside of my pan is being grounded effectively.

One thing that interests me is that the inside edge of my heating element has oxidized and rusted. This implies it should either be coated with something in general or at least when not in use - any recommendations?

Also, since I am getting current from ground to lead, without water in it, doe sthis mean I may have a bad element?

Any idea what is going on here?

I will check the remainder of my extension chord later, to make sure it is properly grounded and the reason I was experiencing a shock wasn't due to lacking a ground elsewhere... but, from what I can tell on testing, it appears my unit is grounded sufficiently.
 
Some people put silicon over the inside edge of their elements to keep the rust off. I am not averse to the trivial amount of minerals it may add to the brew.
