I have to say STEER well clear of the shine....sure its shiney, but get some maguires or autoglym yourself, seriously. Now this will make you laugh...a friend of mine, who works in a garage told me that it costs them wholesale about £10 plus labour....they then put the pimpliest faced tea making no-mark on it..., howver one time it back fired on them, cos the pimply faced no-mark used wait for it.....WIRE WOOL on the bonnet of a new car Lol!!
Needless to say the spotty faced callow youth was duely despatched ..I am sure that in most cases you are not getting a good product used by someone who is intent on detailing our car...you are getting a good product used by someone who is more interested in beer, burds and a night out with his mates than protecting your car....beware...and take some time to do it yourself...its worth it seriously and it allows you to get u close and personal with your new car...without wanting to sound all Garry Glitter about it.
Far better to take your Mrs/ Partner away for a night in a nice hotel having first arrived in the new car...a good excuse if you ask me for testing the car, showing it off and kidding the Mrs on that you care more about HER than the car...tee hee.
