so my GTI had this faking calcium deposit on da hood from my work's parking structure.
one of my bosses noticed it too and told me dat spot i started parking at is no good as the drain from da upper roof level leaks.
better to just park on da roof level when raining and no corner spots open.. faking shittt... took a good while to remove da stain. required polish. but at least it did not etch through the clear..
