Mark,
Terry's real point is that you need to research and learn/read for yourself and not take "common" knowledge at face value. Basically if you get free advice, you get what you pay for. Terry's harping on this instance as just another in a line of mishaps, etc that befall alot of the DIYers because there is so much conflicting info out there and they don't take the time to do their own research and learning. Yes mistakes happen and yes we've all made them, but when you get the chance to help others hopefully learn by telling them they need to read, etc, you've gotta take the opportunity even if it comes across as kicking you while you're down. Shoot, I've made many costly and easily avoidable mistakes on my car and I've taken crap for it and gotten sympathy for it, no different here.
Rick
