Priming iron radiators
I have recently stripped down several layers of old paint on a radiator in my kitchen. I am now down to the original paint coating and at a stage to prime and re-paint, however there are several areas on the radiator where the iron is showing through. I recently tried a primer but unfortunately where the iron parts were visible the primer settled as brown rust patches. I then bought another metal primer, but notice it advises not to use on non-ferrous metals (i.e iron based). Could you advise me please what would be the best primer to use prior to using white radiator paint?
It's about £30 a gallon. I would recommend a Dry Zinc Phosphate primer on bare areas. Johnstone Decorating centres should stock a version for use on a variable substrate ie. for non-ferrous and ferrous metals. Keep house well ventilated as it has a high voc content.
