Seems like a scam
I first applied it on an approximately September first and reapplied a week later. It's now October 4th and I haven't seen any change at all in the black stains on the siding. The package says it could take 6 months to a year for it to work. It seems like that's just enough time for them to make money and then close the company. I believe there should have been at least a slight change by now. I would upload pictures if that was an option.
