I have these spots in a few areas. I can never get them off. I had car detailed few months ago, he tried buffing them out and couldnt get them out either.

any tips?

 

claybar and or ironx

 

It looks like "rail dust". Check out this link. You might have to purchase some items or possibly take it back to your detail guy and see if he has anything like the products in the article.

iron-x

 

Find a real detailer.

 

Find another detailer, if he didn't know how he is a hack. .. you need to clay bar to get the iron particulateout then polish out the brown staining ..

You can remove it all with clay but it takes a lot of rubbing.

 

^hmm?

 

Say what?

 

X2 .. that made no sense at all ..

 

just re-read his post, i don't think english is his first language.

i think what he means is those spots look horrible. get the car professionally detailed to remove those brown spots and to stop them from coming back. also, don't put this off because the spots will only get worse and will harm the paint and body further.
