The difference is that if I know it's been exposed to elements which might compromise the finish, I factor in extra time after each ride to get it clean. 10 minutes with some traffic film remover, careful use of a pressure washer, and some FS365 applied before storage strikes me as a small price to pay in order to keep a 3 year old bike looking like new.
I admire your dedication but for some of us that approach isn't always practical.
