However, I use this Detailer ever since the first day of its appearance on the market, so I can call a small drawback, or we prefer to call it "flaws":
The paint has to use namely a rather dull, rough feel, many enthusiasts who prefer a silky-smooth. But that would probably still as a "matter of taste" by when this dull feel would not promote adhesion of dirt (from splashes) and insects.
Or more simply: I've learned that with the Brilliant Shine Detailer treated einschmutzen car faster and more difficult to clean than other Detailern treated or freshly waxed cars whose smoothness repels dirt better. Where "difficult" here is not to overestimate, rant here to damn high. The car is still much easier to clean than an untreated car.
Nevertheless, the Brilliant Shine Detailer is a great and especially steadfast product, which is why I have opted for 5 star.
