So you found the same as my truck and the opposite of Snipesy's.I've worked on the underside of my truck far more than should be required on a brand new vehicle. I crawled underneath in the dealers lot before I brought it home. I found just the opposite of DieselDrax's truck. No film or coating of any kind.
In fact I was disappointed on how many components were NOT coated. When I build a car, everything gets coated. There is no bare metal under there. I even use coated bolts.
