I noticed a recent thread about painting older galvanised garage doors, and the multiple suggestions for paint schemes. Also that Hammerite,which I have used successfully in the past, no longer seems to be the same product.
What would the team use to get a degree of corrosion resistance on a newly made brazing hearth made of bright mild steel sheet with welded corners which will be stored in a notionally dry, but unheated, garage in the UK? There will be firebricks inside the hearth so the paint will not be exposed directly to the propane torch flame. I don't need a showroom finish but it would be good to think the thing would not look like a rusty mess for at least the first few years.
