Why should you never wax your car again?

You don't have to ever wax your car again if you have a sealant instead of a wax. This was a popular advertising slogan twenty or so years ago with companies selling polymer sealants. And while it had some truth to is, these products did benefit from top-up products which were, much like, a wax.

Newer products like ceramic coatings also mean you don't need to wax your car, and really shouldn't. These too can have top up products which might be like a wax, but thus far these are all for professional application only. So, you will never have to wax your car again if you pay somebody else to do it.
