Same here in Britain.
We've had an exceptionally hot and dry couple of weeks, so the car has stayed pretty clean. The weather's turned stormy now, so the dust has turned to a mottled pattern all over the car.
I managed to get it washed on Sunday morning, just before the rain was expected. My wife thought I was wasting my time, but I really wanted to try out my QD+ so I did it anyway.
We can't complain though, we haven't had a summer for 2 years. The last couple of summers it rained literally non-stop for 3 months.
