Ah sorry, thought you were washing it yourself.
As zaxjax said, you could try ONR if you do want to start doing it yourself. It's a rinseless wash that doesn't require a water source - you can fill up your 5 gallon bucket inside and just use that. Pretty much all you need, and it goes really quick. Once you get familiar with the process, it shouldn't take much more than 30 minutes to do the entire car.
I don't have the balls to try the California Duster on my paint, but with a fresh coat of sealant/wax you should technically be fine. There's just something fundamentally wrong with using it to me, but that might just be me being stupid and/or paranoid.
