Wow! It has nothing to do with products at all. Had this dude used Adam's products, he still would have executed very bad techniques. Which is the source of entertainment and at the same time, tragedy to the cars that he services.
For someone who claims to be a professional and in the business for as long as he has, he opens himself up for this kind of response. At least the man could do is get some professional cleaning supplies (proper bucket, towels, etc.) I would not of executed his techniques as a child.
I understand your want to stick up for the guy, but the bottom line is, if you claim to be a professional, then show me some professionalism.
