"Fall out remover", interesting. Can I get a brand name maybe?
We live in a rural, sugar cane, area & the farmers stir up a lot of dust & in cutting season a lot of them, still, set fire to their crops, massive fires, a traditional pest removal method, snakes & parasites. The fallout is bad in those times. I have cut & polished similar looking pollution from my white ute a few times & it's hard work. Another down side is of course that paint is only so thick. Thanks.
