I think that I am noticing similar results as others after a few washes. There is a slight decrease in gloss. It still feels really smooth to me and after using the QD, most of the gloss and slickness returns....but not all. I have Klasse on another car for 5 months now and it still shines like it was put on yesterday. So there is a durability (of shine) issue with BF. I don't know if this correlates to a loss of protection to the paint. However, I did throw another coat on....took me all of 1/2 hour on and off total. Shine is restored and the shine is definitely more pleasing to my eye than Klasse or Zaino by a notch or two. I am considering layering on some Blitz or Souveran, or even trying a layer of ZFX/Z2. I can tell you that the new layer of BF does a very good job of hiding the very minor swirls that tend to happen with washing.
