I'm not sure what this is but when my car is in the sunlight on my drivers rear quarter panel there is a rather large spot where the paint is a lighter shade of grey. I'm not quite sure what its from, whether its a big scuff or some chemical got on the paint and made a big blotch where it doesn't shine as mirror as the rest of the paint.
Is this something I can buff out with some product?. I don't have a ton of knowledge on professionally detailing.
