There are plenty of different products out there, but the reason the detailers need that time is for the products to cure/go off.
On the higher end you've got the Gtechniq Crystal Serum, Gyeon Mohs+ or Kamikaze products. Then I'd say then next stage down would be Gtechniq C1 + ExoV2, then you're down to normal waxes.
This is just my opinion though, but a new car deserves the best protection you can offer it.
