I am a huge fan of Gyeon products but on a couple of occasions I have been disappointed by their products. This is one rare example of disappointment (relative to many fantastic experiences with their other products). The reason I don't like this product is because unlike an ordinary quick detailer where I can spray it on and completely wipe all detailer residue away with a damp chamois, this product will leave a very thin film of cloudy "protection" that must subsequently be wiped away with a dry towel along with a bit more pressure than I am comfortable with (similar to the process required for applying Gyeon Cure). If this is not done then the cloudy film (almost identical to the film left by Gyeon Cure before a dry towel wipe away) will remain - probably not permanently but unlike a standard detailer, the surface is not left pristine upon the initial wipe off unless that dry towel wipe off step is added.
Mind you, I tried following up the application of the Gyeon Ceramic Detailer with ordinary quick detailer and that did accomplish the same thing. But then you are likely negating the whole point of this particular detailer.

But if you are like me and prefer to use a quick detailer followed by a virtual "no pressure" wipe with a…
