What makes it that, in my decades of being in the business, from detailing, painting, body work, management of two car care chemical companies, working with 9 of the largest vehicle manufactor's in the world, is that this one is not about "pushing products", but a group and a sponsor of the site, that is for "real resolution" of vehicle owners, detailers and the like, concerns.
I hope you could accept my reply to you, and that you take to heart, (with a grain or two of salt) what anyone may reply to you.
Check out their profile's, who they are, what they have really accomplished, if in doubt about what they may offer up for advice, take some time to use that good old "Spock" response to Kirk, "logic".
The net is a wonderful method to learn lots of things, but then it is also full of B/S artist that are only selling or promoting products or building their ego's.
