I wish I saw this post earlier. I have the same thing and then some. My "spot" is toward the passenger front, near the battery. But that's only the beginning. I've been noticing what I thought to be lint embedded in the many wax layers over time. Well, I decided to really detail the truck so I clayed the entire truck, then applied some paint cleaner thinking I'll strip it down real good and then apply polish and wax. Well, it's not lint. It seems to be a paint defect. I have thousands of these little "cuts" in the paint on the hood, doors, roof and quarter panels...everywhere. The detail worked wonders but now my specs show up even more. Has anyone ever seen this on Rodeos?
