This stuff is bad. I've been using it for atleast 10 years now. It was perfect for my dirtbikes, kept them looking new. I didn't even have to put a rag on them, just spray it down with purple power and rinse off with water and I was done.

I tried using it full strength on a RC car years ago and it stripped all of the anodizing right off. I couldn't believe it. I now dilute it heavily so it's about the same strength as straight simple green.
