I don't go along with leaving your paint work for a month or two before coating it with wax or whatever. VW garages offer a sealant service to new cars.
It's utter horsefeathers.
There is no reason not to do it immediately. New paint is hard as soon as it's baked.
I've had new paint polished, sealed and even covered in the clear protective film within hours of it being applied and all has been well.
Again, personal choice, I'd not pay for Supaguard and the likes...
However, if you are busy, I would consider paying a professional detailer to do the works with some quality products.
I'm luck I have a mate who does mine...but a man with a DA or rotary polisher will have small inperfections out in minutes and the paintwork given 4 or 5 coats of something a bit special, which will give good protection for months.
I could do it all myself, but I'm too lazy, and besides two of us can do a better job, in a shorter time!
