<p class="MsoNormal"><span style="mso-fareast-language:JA">It depends in part on which metal you’re covering. On steel, zinc plating (Galvanizing) is to some extent self-healing – smaller scratches actually close over, protecting the steel. Powder coating is
cheaper, though, and (depending on the powder) very durable; it also looks nicer. On aluminum, of course, only powder coating works; but aluminum actually needs no protective finish.<o:p></o:p></span></p>
