How does milk paint perform over time? Longevity and maintenance tips

Milk paint on metal? That’s interesting. I’ve only used it on wood, but I’m curious about your experience with the wax finish. Did you notice any yellowing over time? I’ve heard that can happen with some natural waxes. Also, for anyone considering milk paint on metal, I’d recommend testing it on a small area first. Metals can vary so much in texture and porosity, so it’s good to see how the paint behaves before committing to a larger project.
