Simple question. I have a few cast iron kettles, potjes, camp oven type things needing some R&M ie remove some rust, and re-paint.

I believe there is something called "iron black". That is the name I remember from somewhere in the deep dark past. It is designed for cast iron and helps preserve the iron, ie not just black paint. Tried the local hardware store and they were clueless and just pointed to black paint.

A question for anyone who knows.

The potjes and camp ovens have been seasoned and pretty good shape. The main need is for a cast iron fire pot, it is a round container with an ash section at the bottom, a grid for brickettes and then a grid for cooking on. It is a little rusty on the outside and needs cleaning up.

I know using non-salted butter applied to the iron when very hot "seasons" the iron and helps prevent rusting. Before redoing this, would like to tidy up the areas where rust is to be removed.
