waxing by hand

I'm a new boat owner with zero waxing experience. The boat looks fairly decent right now, so I don't think it needs a super hardcore complete makeover.

A lot of the waxing advice I'm seeing in other threads talk a lot about surface preparation, sanding, polishing, using powered orbital buffers, etc. Right now I don't have a powered orbital buffer, and I'm not sure I really need one at this point. I also don't have the time to remove all the hardware in my boat and follow a 6-step 2-week process of sanding, polishing, etc. However, I would like to do the best job that I can by hand in no more time than half a day.

Right now I have Boat Bling's Hot Sauce for cleaning the exterior of the boat, and I know they make a wax product that's supposed to be very easy to spray on and wipe in/off by hand (though the downside is that it doesn't seem to last very long). What else might be worth doing in between the cleaning and waxing? Is there some kind of sanding compound or polish or oxidation remover or anything along those lines that can be applied relatively quickly by hand? What about the "cleaner wax" I've seen mentioned in other threads? Can that be done by hand? Is it used instead of regular wax or in addition? Any other recommendations for a wax that can be applied by hand but might be a little longer lasting than Boat Bling's?
