you won't be disappointed. i personally use Meguiar's NXT polymer. but i will be trying Zaino's as soon as my april 11th, week build sonic blue '05, GT arrives. if you are curious about Zaino, do a search on it in this forum and you'll get a bunch of threads on it.
i wax my cars every week. but if you tend to wax infrequently, Zaino is supposed to last up to 3-4 months!
i just tried claying for the first time. the results are incredible. i did three of our family cars including a 13yr. old saturn. the old car looked lack luster since i bought it used 5 yrs. ago. nothing i tried seemed to work prior to claying it. i couldn't be happier w/ the results from claying it. claying really works. you cannot get good results w/o claying an old car it seems. it is really easy. when i felt the clay bar actually removing the contaminants, and then the ultra smooth surface as the clay bar glided over the same surface the very next stroke, i freaked out.
it is like magic.
guys use clay on even new cars to get off the rail dust. i'm going to if my '05 ever shows up. :-P the mother's promo video says the most critical time to clay a car is in fact when it is new. otherwise, contaminants will be sealed into the paint by waxing over it.
follow nino's instructions, or other ppl's detailing guidlines which are bound to be similar, and my guess is you will be pleasantly surprised at your results.
