Jim, your car is black and yes you do need a polish/wax and a glaze to hide the swirl marks but for a light color a good wax works fine.

Consumer Reports did a study on automotive wax a couple of months ago. Their findings were that wax only lasted a couple of months at best. Buy a wax that also has good cleaning ability and you will not need to remove any old.

I'm ready to wax the car for the first time (540iA) Was wondering how often you would remove the old wax.

Thanks

Dave

A cleaner-wax dosen't do either job well. And it basically covers some of the dirt with wax.

Best to use a separae cleaner - which removes old wax and other contaminants from the surface, then use a good pure carnuba wax.

Some people also use a middle step - a glaze - but not necessary until your surface starts to show some hazing or swirrl marks.

Cheers
