Does anyone sell a mild steel version that you can paint, or a black painted one? It seems a shame to pay £100 for a stainless one, then paint it, especially as I thought stainless can be hard to paint, and rusts if the stainless steel is not exposed to air...
I have a very fine mesh (fly screen type but mild steel) behind the grille since 30 years to make the electrical fan in front of the rad less visible. It is still in good shape and I had no cooling issues even without using the fan (I only need the additional fan in traffic congestions).
