Collonite 845 - it goes on easy and comes off easy.
I've gotten almost 6 months of water beading when there's no rain. It's amazing how fast rain mixed with road dirt will shorten the durability of the all wax coatings, but Collinite still blows the others away in durability - I even use it on my boat with great results.

I've tried Zymol, but it was a real pain to get off and left splotching light and dark areas on a black car I had at that time - granted I was doing it by hand, maybe a machine application would have helped, but I don't trust myself with a buffer, especially on black.
