If done right it will hold up better than any wet paint you could put on it. The key is in the metal prep prior to powder coating. I used to manage a fabrication shop and we had a powder coat line. It used a 6 stage prep. We had to pass at least a 200 hour salt spray test. We experimented some with the prep chemicals and got that over 500 hours.
