Marks like that are usually iron fallout from brake dust or rail dust.
Use an Iron Remover to get them off the paint without resorting to abrasion. For stubborn cases, soak with iron remover and use a clay bar to remove.
Work fast with the clay as Iron Remover typically dissolves it.

It's iron, or sap possibly if you're parked under trees? Is it sticky?
Agree with Timmy that it's either iron or sap.
I like Stoners Tarminator for sap/tar and it can be picked up at most major retailers. Give that a shot and if it melts off, you know it's sap.

I never park under trees or hardly ever and get them.
I thought bee poop was the culprit.

Clay towel and an obnoxious amount of iron remover to lube the towel will remove it
Thanks guys, my car is garage kept. I will try the clay bar with iron remover.
Since you keep it garaged, do you work close to a rail yard or a steel mill? If you’re within a mile or two of either one, that’s very likely your culprit. My wife works about a mile from a rail yard, and her car, along with all her coworkers’ cars, gets iron and rust deposits all over them. It sucks!
I had similar spots on my daily driver Honda Civic. Adams waterless wash and a Mothers 2.0 synthetic clay pad(shaped like a big computer mouse) got them out without much hassle. Use a generous amount of the waterless wash as the lubricant in it is required & more is better!
Elderado82 wroteNeither of those are near me. My sits in my garage and when I drive to work its parked in a garage.

well, do you ever notice bees or whatever those little buzzy bastards are called?
It is pollen season and I would imagine they are everywhere.
Make sure you let those spots soak for a bit before wiping. Then wipe and spray again if need be.
Poop is acidic and will etch.
