My take is from the pic it is the opposite side fender from the batt location. Another is the probability of the repaint. So it might just be the result of age/faulty adhesion of the clearcoat, but the tree mentioned cannot be ignored IMO.
I live just 2 hrs S of him, and being a West-Texas transplant, (NO TREES) I have been amazed at the effect they have on autofinish since I located here 6 years ago.
Cars that go unwashed get the clearcoat burnt off or eaten off pretty quick....look like a SW sun-burnt finish.....
Since I downsized for baby last year (= no garage ) I could wash my 4Runner, wax it, and within hours would have the specs Concrete is talking about. This lasts the entire time leaves are on the trees (my driveway sits under two large ones). It could be insect related, and is not large drops of sap, but if you go a week without washing, you can rub your hand over the finish and it is like sandpaper. A touchless wash doesn't even remove all of it, it takes hand rubbing.
I kept the hood of the 4Runner clean, and would wash it off 2X week until I washed the whole thing (neatfreak) each weekend. But I did neglect to do the roof as often, and there were a couple of spots forming up there I found when I detailed it for sale (00' Always garaged, never repainted, exposed to this condition for only 4-5 months).
That stuff is nasty, and IMO, will eat anything it comes into contact with it if not constantly addressed.
