Am I wasting my time?

The other day I spent a good 5-6 hours doing my Z4 using the following products;

Bilt Hamber shampoo
Menzema power finish 2200 (machine polish)
Poorboys black hole
Mequiar's liquid wax
Turtle wax gloss guard

Now don't get the wrong it looked great but I also did another car just using one product (greased lightning showroom shine) & the results were just as good and only took 30 minutes. Am I missing something??

The Turtle Wax Gloss Guard is a top coat sealant. It did say to apply after waxing. Assume this is what you mean?

On the instructions it says leave the wax on for 2 hours then apply the gloss guard so not sure?
