Thanks for the info. I've heard about other brands that worked. This one definitely didn't. Its advertised as a bio freindly product without dangerous chemicals. I globbed it on a test spot and covered it with the paper provided and let it sit overnight. Then scraped and repeated the first step again but I was really unhappy with the results. I had a freind that ysed some other kind of remover and then pressure washed it off. He said it worked good. When I try again thats what I'll do.
