Dennis,
I'm with you on the "not spending time with a greasy mess" thing. For me, 500 miles in the summertime is about once a week, on average. I don't want to spend my time babysitting a chain, I want to ride!
As far as a car wash being able to force the lube out of the links, you would probably have to put the nozzle right on the x-ring surface, and even then I doubt it would cause a problem... for the sealed chains to work in the first place the tolerances have to be pretty darn tight or just the torque on them would squish the lube out of the links.
As an update, I didn't go to the carwash. I moved the bike, cleaned the garage floor, and just wiped the chain and the spotted areas off. Then I went for a ride and the chain was much quieter....
I'm likin' this!
