Top half is clayed, bottom half isn't. I went over many of the spots again on the top (there's a few spots left in the pic, just wanted to show the comparo). This was done on a brand new 2 day old 2005 Ford Excursion.
Rail dust...I'm just hearing now that it's very common with Fords, and there is a TSB out. Gonna give the dealer a call tomorrow, because if the paint needs a 3 step wash, they're gonna do it!
