My car too is outside 24/7 but I stay ontop of it, I know NO other way. When its too cold to use ONR I run it through the touch-free wash with a good, strong underbody wash. Before the cold weather hits, I have alot of layers of "Z" on the car and when coming out of the winter, when it warms up, the ONR comes out again. This past couple weeks the weather has been VERY warm, so I've been all over the car. Its like someone said, set your priorities! Unless your literally working/busy all day, there's ALWAYS time for your car and the dew will go away, the weather is warming up and besides, if there's dew, the sun usually dries it up anyways.
