can the ceramic coating be applied on top of the wax?

Ceramic coatings should not be applied over or under waxes. Applying a tile over a wax will prevent it from adhering to the paint and will adversely affect the durability and finish. Applying a wax over a coating will hinder the performance of the tile. If there are problems or failures with the existing coating it may suggest that there is also a problem with Armor Shield.

The best way to achieve this is by basic maintenance or - apply another layer of tile over it. The hydrophobic properties are produced by the ultra-slick surface and shiny appearance that a ceramic coating produces. The guy at advance auto part told me to first wash the car and then apply the CMX ceramic spray coating, wait 24 hours for the second coat, wait another 24 hours and then apply the mcguires spray wax and finally the detailer. Ceramic sprays and wax products probably have a similar shelf life but I would not recommend combining the two.

When a ceramic coating is applied to a painted or unpainted surface, it physically adheres to the surface and creates a strong layer of UV protection. This is one of the main factors contributing to the strength, durability and superhydrophobic properties that nano-coatings are known for. The best way to extend the life of your tile, regardless of brand or grade, is to follow the manufacturer's recommendations for aftercare. The more exposure to UV rays, acid rain (which is a real thing), industrial rain, brake dust and animal or plant toxins, the faster your DIY tile will wear out.

Suppose, for example, you insist on applying paste wax to your newly applied tile. There are simply two ways to maintain and protect the durability of the nano-coating applied to your car, truck, SUV, or other vehicle. By spraying it onto the ceramic coated surface, it fills in those microscopic imperfections found in ceramic coatings as they age and are exposed to excessive weather, UV rays, or other contaminants. I was confused by the comment about finding a "professional to apply the ceramic, you said you couldn't think of one.

In fact, this is why many automotive enthusiasts apply a high quality ceramic coating like Armor Shield IX to their high performance wheels. Even if you spray them off the coated surface, microscopic levels of acids continue to slowly eat away at the surface of the ceramic coating.
