Orange spots ?

Yes three little ones bout 5 feet tall I park it to where it's on the passenger side ..

 

I also get them over the winter. Something in the salt solution they use to treat the roads.

 

Yeah I just got the truck bout a month ago

 

Definitely rail dust.

 

Brake dust as well, unless thats what rail dust is. Its essentially a small metal particle landing on your paint then rusting. Because its small you'll need the claybar to get it off. Works like a charm.

 

Thank you it does look like a rusty color

 

Could be artillery fungus. They thrive near mulch and trees. I used to get those little spots all over when I parked next to mulch.
