What's happened: the intense heat of summer combined with bird dropping landing on the hood of my '24 OT have left a several faint stains that no amount of elbow grease is removing. Short of Clorox and ammonia, I tried every common household cleaner as well as my bucket of Chemical Guys products including spit.
Before using more extreme cleaners, I went back to the very reputable installer who gave it his best try (Nano Wash) to removes the spots. The installer said summer's heat opened the pores of the film allowing the droppings to penetrate deeper into the film. I generally wash my car once, sometimes more, a week. This summer, some of the surface temps in my backyard reached +110-115 under direct western sun with no shade.
So, short of replacing the film on the hood, I'm stuck with the stains. To hopefully prevent further stains, I'm trying one of the graphene spray coats to slick up and seal the surface, which was what the Nano Wash product the dealer used does. I also throw an old horse blanket across the hood during migration season.
