Tried WD-40 and vinegar and the stains are still there. Looks like I'll have to visit a paint shop.
I have similar stains on my white 2014 mega cab, I was told there are rail dust, little bits of steel from the rails of the train tracks from when they vehicles were brought to the dealerships, it get in bedded into the paint. I have buffed them out each year but they seem to keep coming back.
Clay or buffing/compound will only remove or sheer off what is above the paint. The only proven method is a chemical that actually dissolves the iron then washing then claying. Then there is the polishing followed by waxing/sealing or a coating. The outcome is the effort put into the project.

This was my fear with my new truck. I did not want to put IronX on a new vehicle. It might be ok but i was not sure the chemical should touch the rubber seals and other non painted surfaces. So my theory was to try the clay bar and hope not to break the tips off the rail dust. In my mind i would remove as many as possible then spot treat the rest with IronX so as to limit the amount of chemical on the truck. My issue was extensive. I actually had huge streaks of rust stain after morning dew or rain. My truck was changing colors. I lucked out. Every single piece came off and was not bedded too deep. But, since this was my first try i made the mistake of not switching out the clay quickly enough so i have a few fine swirls that may buff out.
I plan to clay bar my truck annually. The paint can get embedded metal particles off the road and from being behind or beside someone while i or they are braking. I have seen sparks fly off of sports cars brakes back in the day but never knew these things get into the paint over time. Semi metallic brakes are everywhere these days.
Just a FYI. I have never heard any backlash or problems using Iron X except the smell. Other than doing the painted body it is used a lot on rims with the purple melted iron running down the tires with no reports of damage. Best to be cautious tho....... even if it is for peace of mind. More damage can be caused claying or componding when those sheered off pieces get dragged or spun around on the paint.
