Thanks Mr. CPHo, looking forward to experimenting!
Thanks Bama! That will definitely get purchased in the near future!
It ended up cleaning up pretty good, I cleaned of the rust spots and chips with WD-40 and 0000 steel wool and the washed it completely with dawn soap, and then oiled the bare metal spots and loaded it with hot coals. I think everything is sealed up for now.
I had a few spots on the legs that were pretty corroded, they also happen to be on the sides that slide across the edge of the lid, probably helping some of chipping that had occurred.
I looked online but haven't been able to find any replacement legs legs anywhere. Any insight on how to get those?
