Along with other precautionary measures, the full-body [[zinc]] coating has proved to be very effective in preventing rust. The body's resulting durability even surpassed Audi's own expectations, causing the manufacturer to extend its original 10-year [[warranty]] against corrosion perforation to currently 12 years (except for aluminium bodies which do not rust).<ref>{{cite web|url=http://www.audiusa.com/audi/us/en2/tools/glossary/chassis_body/galvanised_body.html |archive-url=https://web.archive.org/web/20090221015807/http://www.audiusa.com/audi/us/en2/tools/glossary/chassis_body/galvanised_body.html |archive-date=21 February 2009 |title=Audi of America &gt; Glossary &gt; Chassis & Body &gt; Galvanised body |publisher=Audi USA |access-date=27 April 2009}}</ref>
