Watched that part of the video. I wouldn't dispute anything this guy says, great products but........ I have a Graphite Crossfire. Its 5 years+ on the road. It has no swirl marks. I use the same bucket but its a Zaino bucket, Maguiars Gold Car Shampoo. I dry with my leaf blower which by the way does a much quicker job of drying the car and very soft 100% cotton towels to finish the job. Then I go over it with detail spray.
The foam is an interesting concept as is squirting the whole car with detail spray before you dry it. I've never heard of that one before. I think someone before me said it will require a good deal of "product" and that seems right. A jug of Meguiars lasts me months. I am impressed with amount of suds from the Adams wash. I just switched from Zaino to Adams wax products and I'm very happy I made the switch.
