My daughter moved to a new place in August and was parking her car under some type of scrub tree that produced berries. I don't know if the berries themselves dropped onto the car or if it was bird droppings that contained the berries. Of course she didn't wash the car for a month and now the berry remains seem to be baked in from the sun.
The paint color is white so it's very noticeable. I have not found any product (list below) that will remove it from the paint - none. The only thing that is working on the paint is being aggressive by hand with a compound and polish.
Although as bad as that is, it's the stains on the vinyl wrap (front 18" of the hood) that are proving impossible to remove. I've already tried rubbing them with every product in my garage including: clay bar, dawn liquid detergent, WD-40, Seafoam, liquid propane, turtle wax road and grime remover, E-85 gasoline, 50% white vinegar solution, a mold release agent, and even urethane paint reducer!
None of these made any difference at all, and on the vinyl, even the compound/polish will not work. How can vinyl hold up to all of those products yet tree berries are doing a number on it? Do the stains somehow migrate into the vinyl over time - very strange?
Before I give up I thought I'd see if anyone has any other ideas.
