I personally believe there is a lot of bad information in them, and that his attitude towards others that are trying to learn is terrible. I have seen multiple posts with him becoming angry and defensive whenever his techniques are questioned. He is no longer associated with Adams, so I wonder if there is a reason for that.... Also, check how many other detailing only forums that he posts on....there is a reason for that too...
That said, that is my opinion, and I honestly don't want to get into it too much in this thread since there is great information in it that shouldn't get overrun by the topic of Junkman.
