It is annoying, but is ok. The more humidity, the more quickly it will happen.
How much do you drive? I learned from a professional detailer a while back that in many cases, I didn't need to be washing my car frequently. He suggested interim detail products and I have gone that route ever since. Certainly need to be careful and cognizant of how the car is used but I don't put many miles on my car and I'm not going to regularly wet everything down.
Perfectly normal...especially on Ferrari's! Just be sure to wash any of the rust off that gets on the wheel surface, paint, etc. It will not hurt anything when it remains dry. But if it gets wet and is allowed to remain on the surface it will begin to break the clearcoat, paint, etc., down. Nothing to be concerned about unless you frequently let your car get wet without wiping it down.
