Bob,
I think you are getting all of the different front end shield materials confused. Everyone uses Diamond Shield generically (like Kleenex is used for all facial tissues and Xerox is used for all copiers and the act of making a copy). The 3M films seem to be the biggest problems that I have seen.
The new Diamond Shield, labeled nano fusion film, is really good stuff. Maintenance is minimal - a few spritzes of 303 once a month and you are done. There is no reason to wax it as the only recommended maintenance is 303 monthly and wash the bugs off as soon as you park for the day.
