You should be fine as long as it is a "touchless" (no brushes) car wash.

You never want to take it to a wash with brushes. Used to you had to worry about the brushes scratching your paint - the newer ones aren't as bad. But the brushes can pick up things. My sister had a car beat up by a car wash brush that had picked up some kind of hook off of a vehicle and when she went thru the wash, that hook made nice dents from one end of the car to the other.
