This wasn't apparent at pick-up a few weeks ago, but has been visible from certain angles after the first time I took it to a touchless car wash in town several days later. There has not been any mud, dirt, bugs, bird poop, or other grime on the car to match this change at all. There was no residue on the hood at the end of the car wash. I've washed it by hand and at a touchless car wash since, and it hasn't changed at all.
Any ideas what this is and what can be done?
