Ever heard of this?

I posted on Joannes campcook site but
I was reading a magazine that had a list of helpful hints. A woman from Wisconsin suggested
After washing a cast iron skillet wipe it with a wad of wax paper while it is still warm to prevent rust.
Not sure I want melted wax on my pans. Anyone ever heard of this?
