Superguard is just a rip off. the dealers very often don't apply it and sell it on ebay or apply it with a brillo pad.
This is fact BTW, I know a car sales manager and he has sold loads of this stuff on ebay that customers have paid good money for and only ended up with some halfords own brand polish that was done by the service teams car wash monkey.
Apply a good quality polish yourself and save a ton or so.
