Hi All - I'm in the process of cleaning up an offset smoker and I'm about ready for the next step. After I get the rust knocked off the outside of the firebox, should I repaint or just heat/coat with either crisco or veggie oil? I've done a lot of searching on painting and see a mix of preferences / results. Some have paint issues, others don't. Some recommend paint, others say oil it or use crisco. I don't care too much about the appearance. I'm just interested in protecting the health of the pit long term. It already has some years under its belt and I don't it has had much TLC. I'm curious if oiling it while hot is the way to go to avoid the potential for having paint issues soon after.
