Premature failures of coatings applied to galvanized mast arms is not an unfamiliar problem1. The properties of galvanizing that make it a difficult substrate to coat when new don’t simply disappear from beneath the original coating system. When maintenance painting is necessary after a few years of service, long term success can be elusive. This paper will discuss the development of maintenance painting process developed to accommodate budget constraints and produce a satisfactory outcome.
