I do remember that and the confusion/frustration it caused. I thought the naming convention was a large part of the problem and the did eventually fix that. I was a part timer and fought hard to get the proper pricing for the coating and in doing so I only did a handful of applications because I wasn’t willing to undercut the price and value.
Over the time I have come to think that “Pro Only” is a bad model. Look at mechanics, painters, IT (computers), designers, and many other professionals. I can go buy the same tools, parts, hardware they do and use them all if I am willing to pay the money and put in the time and effort to learn how to use them properly. I have seen good and bad paint jobs from “professionals”. And I have seen so really good or bad details from professional detailers as well.
I now look at it and think that a company like Opti could sell the Pro Only products directly to consumers if they wanted to and then could control the process a little more to help make them feel comfortable. They would have a full list of people and applications if they wanted to offer the warranty. But if it were me I would only offer the warranty through the pro with the insurance backing and just the coating to the ProSumers that put I the effort to get it. I don’t think many would go out of their way to order directly from Opti when then can just do bulk orders from the wholesale warehouse sites.
