Best wax for lazy people?

Called a fellow that details cars, he came to the house washed, did some kind of secondary cleaning to prep the surface and applied something he called a ceramic coating. I assume it is some type of hi-tech wax. He said it would last at least a year and if it didn't still bead water in 6 months he would do it over for free. 20 Year old B van looked like new including the fiberglass hightop. Price included tires and the all outside stuff, interior was extra. $150 for 3 hours of hard work seemed like a bargain to me, he had allowed 4 hours but finished early. He had figured in the extra hour in case he needed it. Only warning was to use mild soap when washing. He said for most dirt leaving it out in a hard rain would be sufficient and so far that has what it has gotten and it looks pretty good and beads nice. I will give it a quick wash before our October trip, the lower area around the tires and the hood could use some cleaning. I will be calling him again in the Spring and let him do our car at the same time.

Very easy, I just walked out every 30-40 minutes to see how the progress was going.
