I guess that would be me
I'm in the middle of doing a set of wheels, so here is the quick notes.
Wash the whole car. Strip wax if needed on, say 1/2 the roof. Clay the area, polish, wax. Next day, light wash if needed, strip/clay/polish/wax,......
I Black Wow the whole car first. If I'm under 3 days for the whole car, I do a second coat of wax, Epic in my case. Wait a day, then Banana Gloss the whole car. If I'm more than 3-4 days, I skip the second Epic, and just BG. By then bad things are probably on the paint, so I don't want to seal them in long term.
Biggest thing, make sure the car is CLEAN for each session, as you will tend to overlap sections.
