Update: Well, after 3+ months, the car still looks very good. In fact, I've had a couple of comments this winter.
Beading is clearly flattening out, but the surface still feels smooth and relatively clean. Car washes up nicely, but not as nice (or as easily) as the car coated with WS products.
As indicated by the folks at FK, the combo I used should be good for 5 - 6 months and my experience seems to be proving that out. While we haven't had much snow/crap on the roads this year, the car is being washed weekly (ONR or traditional).
I am very much enjoying the FK wheel cleaner. That's been a good investment and meets my expectations. I still luv that pink QD #425 spray by FK...cool stuff if you haven't tried it.
Next up: I prolly do one of the 1Z polishes followed by the Glanz Wax, which I have a little remaining. That should look T-riffic on this garnet red paint.
