I normally hand wash & wax my cars in my driveway. Lately I've been sick, and work is piling up and I just don't feel like taking an hour to do this. Plus, my van's paint is peeling anyways. So today it will get a coin op wash. I noticed when doing this with my highlander yesterday, that they have a wax setting on the dial. I would like to try this with the sienna. Now is this the last thing you do before you drive out of the bay? Or do you use the wand setting to rinse the wax off, before leaving?
