I didn't experience this but listen to what someone wrote at Bimmerfest:
Rain stripping it off??? What are your thoughts.

I personally used to use Gold Class, but I was never an avid car detailer. I waxed my car about twice in the two years of ownership. However, using NXT, I cannot say that it is any better than Gold Class. However, this MAY BE because I never observed the quality of the wax until now. During the rain last week all the NXT I could feel had been completely stripped off. I used the quick spray NXT, but during the rain the next day that was also stripped off. So therefore today i waxed my car again since I had plenty of time to mess around. 4 hours later I had new coat of NXT on.
