I use 3m Imperial hand glaze. I do some detailing on the side.This is the best stuff I have used. Will take all the little fine scratches out. Can pick it up at most paint shops.
Rydeon, If you're really looking for the absolute laziest, Ford/Motorcraft makes a Carwash + Wax all-in-one bottle mix - kind of like using Pert Plus for your hair. I'm sure it's about as good for your car's finish as Pert Plus is for your hair, though.
I use Meguiar's NXT or Yellow wax. I think the yellow wax gives a deeper shine but I guess I'm going to finish this bottle of NXT. Twice a year I go over the entire car with 3M fine cut polish for dark paint. This makes the paint look a little darker and have more depth to it. Then I go over it with the wax and use an orbital buffer with a microfiber bonnet or whatever you call it.
I vote for Zaino, but if you're like me and don't have a bunch to spend, I use a Megiuars polish and glaze then NXT Tech Wax. The NXT stuff is almost as good as the Zaino, it just doesn't last as long.
To the guys that voted Zaino...I agree, it does kick butt for shine and durability, but I just can't get over the multi-step process and how much effort it takes to properly use the system. I guess I'm lazy. If Zaino was just a 1-step process, I wouldn't use anything else. But man, that shine...and it lasts/protects for a LONG time!
