Bigboy & JPS - Yes I did use the BF car wash. I ordered the complete kit.
As for degradation of shine & slickness, it rained Thursday and this car does not get garage space 24/7, so maybe that has something to do with it? My expectation for BF is higher than this though. Maybe they will hold up better after I slap on more coats. Guess I'll put 2 more on this weekend and see how it goes. Don't get me wrong, the car still looks pretty darn good after the wash. Just not the same and slick comparing to "just buffed" finish.
One thing I like is the drying time. From what I feel, it dries even faster than ZFX! Of course, I took a lot of time to lay out thin coats.
