If, it's a cheap Chinese scoot, you need protection because they usually use poor quality paints, chroming, etc... I would not bother using these aftermarket undercoats... In riding thru salts, a good rinse of fresh water after each ride will be enough to prevent rust formation... If I live near the sea.. that's another story... Also, scooters have less metal surfaces than motorcycles... What you need to protect, Stig, are you chrome bars...
