Polishing and sealing Neuwagenlack? Collnite 476s?

Hey guys, I get my new Fiesta ST in Performance Blue in 2 weeks and yesterday at Lupos alone I spent a good 150 euros for new toiletries. Finally I bought this 2 Grit Guard bucket. With this car I want to make it perfect and wash it only with the 2 bucket method. If the car comes new, I will definitely wash it immediately and seal it with Collnite 476S wax. That should give the new car shine a nice look. After every laundry w I will treat it alternately with the P40 from Chemical Guys or the Sonax Detailer, in order to give the wax protection over and over again. But ask now, for me as a layman, the new car coat looks great. Would it make sense to polish it before? Menzerna 3800 Plus zb? So only a pure finish polish? How much can you get out of a new car with it? Even this polish has a slight removal to remove holograms etc., however, I do not know if this can be done with a new car. I don’t think it’s endless…I’m thinking about giving him a polish after a year.
