Well, not so fast. I'd suggest that maybe the issue is what
Meguiar's calls a "cleaner wax" and what chemicals Autopians evaluate as being "cleaners".
I agree with the
Meguiar's Customer Service Rep's statement "NXT was designed to be put on a pre-cleaned surface in order to work it's best." In my testing,
NXT Tech Wax did not clean the surface of my Cayenne. If it was a "cleaner/wax" the surface would have been clean, polished and smooth after an application. This was not the case. I intentionally put NXT Tech Wax on a paint finish needing cleaning to see how it would respond.
If the Meguiar's Customer Service Rep failed to understand the difference between a "pure" sealant that can be layered and a product that has chemicals that remove previous layers of product, that's understandable. After all, most people do not spend their days applying layer after layer of product. They apply, admire and walk away.
In my mind, there is a clear distinction between a cleaner/wax, a sealant that removes previous layers and a
pure sealant. We should define that distinction here and decide where products fit based on experience.
