Hi Lip, I'm the guy the writes the detailing forum on the homepage. (turbomangt) visit my web site and see "detailing tips" read through them, if their is still a question you have e mail me direct. I spend a good hour responding to car care questions for people all over every night. I have a passion for this stuff. Clay, once you figure out how to use it, you will never be without it. Bluegt is correct in that it removes contaminants that the wash stage does not. Their are a few tricks however, which would take too long to post here. Bugs can be removed before the clay process, and tar can mess up your clay bar, which is why you should use a cleaner to remove the heavy stuff first. Clay is an amazing product though. As far as waxing (I prefer to paint seal, it will last 5 times longer than the best wax on the market) you should do that right away, after you detail/clean your car. Todays paint technology does not need to cure like single stage stuff of long ago. Visit my web site for more info>
