I previously mentioned that I didn't see any on mine but when I was detailing the car this past weekend (I wipe down and lightly wax as much of the painted areas under the hood as I can 2x a year - road salt is a beast) I took a look with better lighting. I have some very minor dusting in the same spot. I will probably wipe away and see if it returns. Guessing there is some type of lubricant or sealant residue left over from the manufacturing process and it is picking up dust. Seems pretty consistent with the images from post #7 and #18 vs what the OP posted which looked more concerning.
