In this video I'm using my Dupray Tosca to steam clean the exterior of my black 370z. I follow it along with an Eagle Edgeless microfiber towel from The Rag Company. I would say this works good in full sun, no water spots, no need for soap, and uses very little water. It's handy in the winter time if it's really cold and you don't want to chance getting water everywhere that will turn into ice. The Dupray Tosca also works great in the house for sinks, floors, toilets, bathtubs, without the need for any harsh chemicals.
