I am using Plexus, an excellent aircraft plexiglass polish/protectant/cleaner that I have used for years on motorcycle windshields and helmet shields.
I can't say yet, obviously, whether it will prevent yellowing of my JSW's headlights over time, but it has helped prevent that on my bikes and it has none of the possible drawbacks of film.
BTW, one of the worst things you can do to these kinds of materials is use alcohol-based cleaners (Windex, for ex.). That will make them "craze" and yellow a lot faster. My wife's Passat is unfortunately proof of that.
