The Brightside does have Dupont something-or-other which I think has to do with ease of cleaning.

My car is in the garage, and even it gets crap on it, but it has been easy to clean with the Brightside on it.

The Brightside will also give you a much nicer gloss.. since your car is already white, it shouldn't take more than 2 coats to get a nice shiny Brightside finish on it..
