So I was filling my tank for tomorrow and I thought I would be smart, and I added a splash of roof snot in there, thinking it would mix as I drove. Big mistake. I was distracted for a minute and when I turned around, there was a three foot high solid column of soap suds coming out of the manway. It was unbelievable, of course my camera was sitting at home on the kitchen table, that would have been an awesome shot. Anyway, Russ hit a home run with this stuff. I was adding it to my mix for a giant,very dirty driveway tomorrow, and I want suds sitting on it for as long as possible. I picked the right stuff!
