Much in the way DEVO wore their radiation suits, the mechanics, and everyone for that matter, wear protection for any kind of danger, seen or unforseen, such as rain, shine, cancer, AIDS, fuel, rejection, and flying Webbers.
On the subject of DEVO, the work suits would look great in yellow.. Someone needs to edit a photo of the Jordan F1 cars..
