The first step in preparing galvanized gutters for painting is to clean them thoroughly. If the item is exposed to continually wet conditions the zinc develops a film known as white rust. Hot dipped galvanized steel and electroplated galvanized steel are made using different methods and their zinc galvanized coatings corrode completely differently. Galvanized steel despite its protective coating will usually be destroyed by rust within 20 years.

Galvanization involves zinc which corrodes instead of the actual metal to prevent rust. Galvanized steel has been used for almost 2 000 years because of its unrivaled ability to last a very long time and resist rust. Left untreated white rust corrodes the zinc and the metal underneath begins to rust exhibiting the more traditional brownish red color.
