Thanks for all the ideas. I did state in my original post that it is all the way around the car. That means including the bumpers, although admittedly it is somewhat less evident on the plastic parts. I'm pretty sure that rules out rust or brake dust (I don't think you can get brake dust on the front bumper...unless you drive in reverse a lot.) However, a fingernail test tells me the spots are raised. I'll have to try the clay bar to see if that will do the trick. If so, like @jjrandorin, I'll find a professional do the whole job for me.
I've never seen anything like this on any car I have owned, which is upwards of twenty at this point. My other current ride is a white Porsche 911 that is 20 years old with 10 times the mileage, and it doesn't have any such spots; paint chips from road debris, yes (I call it my chip magnet), but no orange spots. That car does not have PPF, either.
