[Sca-cooks] Not so Virgin Cast Iron Question

[Wanda Pease]

My brother just gave me a nice size cast iron kettle.  Now I happen to love
cast iron for use around the mundane house.  The problem is that this
particular pot was used to cover something outside and only recently
rescued.  The interior bottom is badly pitted and rough.  The question is:
Is it worth putting the scrubbing and possibly sanding with a disc sander
into this?  Should I use it as a planter?
