I have both Wolfgang 3.0 DGPS and the Woflgang Fuzion. The fuzion is nice but for all around durability and ease of use, I go for the Wolfgang Deep Gloss Paint Sealant

 

collinite No. 845 would be my choice. Cheap and durable. easy to use as well.

Zaino does seem to last forever indeed. I can honestly say that about 9 or 10 months after I waxed my car with Zaino, it still beaded up very well. It also looks very good. The negatives with Zaino is the fact that you have to mix it with their hardener the first time, and the ease of use. It goes on with a buffer pretty easily, but getting it off is a HUGE PITA. All I used to use was Zaino, so I really had nothing to compare it to. After using P21S and Werkstat AJT, Zaino is much harder to use. P21S doesn't last all that long, but gives a good shine. It's a little on the pricey side though. Werkstat AJT is very very cheap, is SUPER easy to use, and gives an excellent shine. I don't know how long it lasts though. It's been about a month and it's still beading, but I did top it with Zaino.
