I have the same problem with my white truck. I guess it's just road particles that fly up. I just clay bar it and that takes it off, but I could see it being more troublesome with a brand new truck covered in rail dust. I'd probably try to fix it myself, but if the OP isn't comfortable with that, ask the dealership to make it right.

 

Rail dust is the term used but its from a variety of sources. If you have a light colored vehicle and especially if you live in an urban environment, your susceptible.

 

Good suggestions with the clay but I think ill let the dealer tackle it as it should've been taking care of before delivery

 

i have it on my 09, kind of ticked too been trying to find some options to get rid of it, im still debating on trying to get the dealer to acid wash it.

 

They only cover it for 12 months or 12000 miles unfortunately.. which is crazy for a 40k truck

 

Look at CarPro Iron X. It will become part of my spring detail. Sometimes claying will not remove the iron that has chemically reacted with the paint and is more of a film than a solid.

I get a little bit from time to time on my truck. I pop it off with my fingernail and then try to wash the underspot real well

 

What about a weak solution of Iron Out? Just don't know what it does to painted surfaces. I suppose you could test it out on a cheap paint job like the old lawn tractor in the back yard and see what it does. Seems that if it was harmful you'd be able to tell right away with a lesser quality painted surface.

Just a thought.

 

Had it all over my white 2011 Eco, took it back to the dealer and they used a clay br process (I think) and removed it. They seemed to have gotten it all, just watching it close for a while to be sure. This thing was very rough in spots, noticed it the first time I hand washed it. Rail dust sucks !!

 

This stuff keeps coming and is a constant problem. The biggest source is your own brake dust with the semi metallic pad compounds. It sprays up off your wheels and off the roads in wet weather, sticking to your paint, mostly behind the wheels and up the backside of the vehicle. White is the most visible color of coarse when the little bits of steel get wet, salty and rust.
Even the snowplow blades leave steel on the roads that your tires kick up in the rain.
