[Supernatural] If I wear an iron ring on my finger, am I immune to ghost possession as I would be continually touching iron and thus expelling them?

No, but you would have the benefit of being able to punch the ghost in the face when it tries to posses you.  Speaking of which, why don't hunters wear an iron and a silver ring all the time so they don't always need to find it in the environment or end up misidentifying a shifter because the silverware wasn't real silver.
