How often should you wax your car?
I've been cleaning my e36 328i sport once a week fully wash,wax etc
How often does it need to be done?
Also i don't quite understand how wax works once i wash my car again does it wash the old layer of wax off or is the old layer still there?
And anyone got an alternative wax as good as the Auto Gym Wax which is 30 pound a shot but cheaper?
