If its only a hydrophobic wax then it shouldn't really be marketed as a ceramic wax.
Ceramic coatings are completely different, literally a barrier so to speak. I was looking into getting the G Tecniq ceramic coatings with the applicators, but need 24hour curing time at least. Was a bit surprised when I seen the ceramic wax by Meguires. I have a cheap oul ceramic spray at home I bought AGES ago, IMO it's just a wax, or a detailer spray, but has no long term durability to be marketed as ceramic to be honest. Think it's GB Detailing brand, as I said, ages old and haven't used it since.
Ceramic coatings should only be used on a car that's had its paint been fully decontaminated and cleaned properly, once applied they should have at least 24 month durability. Supposed to be very hard to remove too.
This is the proper coatings now, but dirt literally sticks to the water on the car, rather than the paint.
I was just wondering about this one, cause obviously when doing a car for someone else, you want to make it as affordable as possible while still having some means of protection on it.
Sealants are good too, but as Tommy said, ceramics are the buzz word, and really top tier stuff
That's my take on it anyway, if I'm wrong, please do tell me as every day is a learning day
