SoCalBoxster,
zaino will give you much better results than Meguiars, and will last longer (coming from a person who is sponsored by meguiars), it will give it that nice shine.
although i use everything meguiars and then top it off with zaino z2.
zaino goes on soooo easy, its instructed to put light coats, lighter the better, and it whipes of so easy as well, no effort whatsoever. that is why people end up with crazy amount of zaino layers (ask Bmussat how many he has), and i did have about 8 or so on mine, but when using a claybar, you would want to wash the car with Dawn, it will strip all the wax and protection off it, giving you a good start on claying the car, after that you want to polish and seal it.
unklekraker,
i used the griots garage one, with pretty much every single meguiars product.
i was suprised how long it took me, and kinda forgot how small a boxster is compared to a full out 4 door saloon mercedes i recently did, phew.
so pretty much i went over the car with diff pads and diff chemicals/products 6 times, then zaino by hand
