If you've ever tried painting galvanized metal — metal that's coated with a thin layer of zinc to prevent rusting — you know it's pretty much impossible. Some paints might stick at first, but they'll eventually peel. That's because the zinc reacts with paint's binder and will create a film that causes the paint to peel [source: Sherwin-Williams].

So it's important to follow the correct procedures when painting galvanized metal.

Once the paint dries, it should be good to go and you shouldn't have to worry about it peeling.
