I was cleaning my mom's and brother's cars today. I noticed black spots on my brother's car a gray spots on my mom's car. They rise above the clear coat. I tried claying them off. Then I tried buffing them off. Neither seemed to work. I even used tar remover thinking it was tar. Does anyone know what these are and how I can get them off?
 
Try to take some photo's so everyone can see what it might be and someone will respond to this post, and might have the answer your looking for.
 
These are the spots from my brother's car. They are circled. I hope the picture is good enough, it was hard to get them.

I have the exact same problem on the rear bumper of my 04' Red Nissan Sentra SE-R



I've been meaning to ask myself.. hope you get an answer.
 
I wonder if they are soot from the exhaust? When you start an engine, all of the humidity in the exhaust burns off and carries soot with it, maybe it blows out of the exhaust, curls back onto the rear bumper in the vacuum that the car creates as it pushes through the air, and then is deposited on the back of the car.



Are these only on rear surfaces?



Just a thought.
 
I get crap like that on the car sometimes. God knows what they are, but a plastic razor blade, elastofoam block or aggressive clay will fix them every time. If you're doing a full detail, a compound by rotary will knock them off.
 
good to hear.. ill find out in October when my car is due for some winter prep if that fixes it for me. clay (not aggressive mind you) didn't budge it.. you can't even feel it.. (in my case anyway)

Yea, clay didn't do anything. I used Mothers clay and Zaino's clay.
