jn328i, have no fear, your car will surely look great.
The best thing you can do is prep before you put on any sealant. Look really close and feel your paint (feel it throught a gladlock) if there are bumps or if you can see little tiny rail dust specs or if there is oxidation (I mean look close), try to get rid of all of that (SMR for swirls, maybe some PPCL). Also look to see if you have swirls in bright lamps at night, like parking lots or your garage.
After prep your white car should be soo bright and clean, almost brand new looking. Then you add Klasse and you will fall over it looks so good :up (take before and after pics too
)
most of all have fun with it, we're all here to help you :bounce
