    I've heard you need to wash it with vinegar before you paint it. Something about the acid in the vinegar...?

    just go to a paint store and talk to them there. Tell them you have galvanized metal and they will tell you what you can do. They are well aware of what their paint sticks to and galvanized metal is tricky. There may be a 2 step process. They know.
