AM stuff is made for the pro detailer, commercial car wash, etc., who needs to buy in bulk. It's good quality products for what it is (comparable to Pro, Malco, Ardex, etc). Zaino is on the other end of the scale: made for serious enthusiasts, show car owners, OCD types, people who hang out at places like Autopia.
Two very different companies making products for two very different target markets.
