| vic99 Here in the US, many welding supply distributors carry a spray paint product called Cold Galv. I think is also available in gallon cans for larger jobs. Not sure what your application is? wiredheart |

| Galvanized metal has a greasy, oily coating to protect it during storage/shipment. This must be removed before it can be painted. Additionally, some sources recommend letting the galvanized surface age before painting it. Rustoleum carries a latex-base primer that is supposed to be best for galvanized or aluminum surfaces. I am not sure if it is necessary to use a latex top coat, or if this particular application would take a more traditional oil-based enamel. I have used Rustoleum Red Primer (lead-free) followed by Rustoleum Gloss Black Enamel on weathered and/or once primered flashings and such on my roof. I let the Red Primer weather for a couple of weeks in the summertime to enhance the result. It seemed to work ok, but being on the roof the work doesn't get very close inspection. From the ground, it looks fine. |

| Use Ospho, a phosphoric acid solution, to etch the coating, follow the instructions. Then use epoxy paint for a durable finish. I like Ameron 400 because I can use it in small quantities as the mix is 1:1 Thierry |

| My elderly neighbor told me just to wipe down the metal with vinegar and then prime and paint as usual. I haven't tried this yet so you need more input. But, if it works it is a very cheap. |
