"The three types of VW are slightly different. Their "base model", the Cruising has polymers in it, so it provides the best durability, while the other spectrum, the Concours is purely an optics-tuned product. The Collectors contains a bit less carnauba.
There is a problem though: all three look seriously good, and all are surprisingly durable (2-4 layers, of course). For me it is a wondrous, fulfilling experience to use them."
