I have been reading a lot of hype on line about color specific waxes, such as Zymol Rouge. The idea is that the wax contains special components and ingredients that bring out the depth of a certain color, most focusing on red, blue, silver/metalic, and dark colored cars. I recently aquired a client who owns 11 cars, and all of them are red. Would it be worth the investment of a red-wax for this client? My own VW R32 is also red, so I suppose I would test it on my car first, but before I purchase a red-wax, I would like to know if anyone has experience with these color specific waxes and if they are worth the extra money.
