Kind of lazy if you ask me.
How would you go about telling the customer the roof will be coated only and not waxed and at what cost?
Ummm, the only customer is me. But, that being said, this actually sounds like a great idea for those that maintain an SUV for money. Since the roof is a large flat panel, and sees a lot of sun (UV), water sitting on it (water spots), etc...As long as you agree that Opticoat provides better protection than wax, also more skill to apply.
But, once it's done - it's done for life. I do like trying different waxes, so this seems like a good way to continue to do that, but eliminate some of the PIA parts. I used to do the whole "process" for every square inch every few months: clay, finishing polish, glaze, seal, and wax (to try a different wax).
Really, the issue is my garage is a 1 car garage and very narrow with a low ceiling. An SUV barely even fits in it, you can hardly open the door. Trying to work in the roof in there is terrible. In order to work on one side, you have to pull in so the other side is literally 1" from the wall. The, to do the passenger side, you have to pull the driver's side 1" from the wall, and hop over the console and get out the passenger door. Doing the hood / panels isn't as bad because you don't have to keep dragging the platform around.
So, I figure all that when you can't even see the roof is a waste of my time and products just to switch to a new wax every so often. The bumpers I will Opticoat and likely just apply wax over it if the mood strikes me. There isn't a lot of bumper on this SUV, but the front bumper is a bit intricate and just not enjoyable to work on. If I "start" polishing a bumper, I have to do every square centimeter of it perfectly. I just have that type of mentality. But, I figure if it's Opticoated, I can just clean it with Eraser and wax it when the time comes.
