Claying refers to rubbing the finish with a small bar of clay that has been softened up in your hands. It picks the bits of dirt and impurities that washing leaves behind. You can feel the impurities in the finish by wrapping your hand in a plastic bag, and rubbing it over the finish.

So, I wash, then clay, then polish, then glaze, then seal or wax. With a polisher, it's easy, and makes your truck look fantastic.
