Collinite 476 is also one of my favourites, a proper old fashioned paste wax.
I use this as a finisher/beading top coat after polishing on the other cars. Been about for years but still very good.
Not exactly cheap but the tub will last a lifetime. 
Which one would that be then, have a couple?

Just been out to the garage and mine is 476S. It's in a gold tin (not plastic) and although I've had it for years it's barely touched the amount in there as I put it on with a round sponge applicator. It is not a polish as such but more of a coating to enhance the polish that that you've already put on there.

Beading properties are pretty good after this has been applied.
As said before, my son used to do full on detailing and dent repair as his day job and it's bloody hard work. Paint prep, clay bar, working out high spots, low spots, removing swirls, and that's before you even get to the polishing stage. His results were fantastic though as he's a perfectionist.
Realistically though, the average person can't dedicate this amount of time for a super shiny car, so they wash it, dry it and are happy with that.

As with all of them, the elbow work needs doing first to get the shine. If you have access to a proper variable speed machine polisher, a proper going over with Autoglym Super Resin followed by collinite is plenty good enough for most folks.
