After a year of washes, about every other day, the chemicals and overhead brushes have begun to stain and wear and tear my clear-coat on my black car (See photos I posted of my black hood and roof. It shows up as a gray glare on my shiny black car.). As much as I like their people, their system has damaged my car in several other ways as well. I have cancelled my monthly membership, unfortunately. I am going back to DIY car washes.
