I completed my "series" products Meguiar 's with this clay-kit. In general, their products are amazing. Their marketing "old" who says to forget the competing brands with this miracle blah blah ... actually keeps its promises, including the ultimate compound that buries all other products on the market. The clay kit is less spectacular, it is for maniacs, but it actually recovers all pollutants deposits even on a body that has the nickel air.
