Last weekend, I applied F11 on the X3. I hand washed it first with their version of the wash, scrubbed all the wheels clean, etc, I applied it everywhere, on the car, glass, and door jams (just realized I never opened the hood area. Anyway, after I purchased this stuff, I have been watching some videos out there saying that with some minor everyday chemicals, the coating just comes right off. In case anyone is curious, I will report back exactly how long it lasts. My wife drives the car everyday, sits in a garage at night, exposed to rain, sun, winter weather, etc.

My guess will b 3 months before it wears off, we'll see.
