I've worked with Production products before, and they really are decent products. Just like anything, the end result heavily relies on the process, and the method in which you do it.
I can take products by Meguiar's, Optimum, or Production and make them all look the same. As long as you're dealing with something *decent* you can get a nice detail out of it.
That being said, this guy is a salesman. He's being paid to go around and promote this line, so you can't blame him for acting like a salesman.
And as far as the product line, you certainly can't expect to see gallons and gallons of high end *boutique* type products (like we use) in places like car dealerships. When the only charge $50-$100 for a full detail, they have to cut corners somewhere.
By the way, I actually own some "Midnight Special" and when you don't have time to polish a black car, this product really does look insane, BUT only for a couple days because when the glaze washes off, it goes right back to looking like poop again.
