I recently tried the B & Q "Special metals" primer, on both brass and galvanised iron. (Not steam related items though.) Subsequently I tried to remove some of it, and found it almost impossible to do so. Previously I have tried the Phoenox primer, and bead blasting, (not both at the same time) and found both worked OK.
