I’m a bit leery of “ceramic infused” products these days as there are SO many on the market.
In my opinion I’d do a good wash, decontamination & paint correction followed by a true ceramic and maintain with a “ceramic booster” or “ceramic detailer” after the ceramic coating is cured I suppose a good wax over the top will not hurt but at that point you’re not applying the product on the paint ; you’re applying it on top of the ceramic coating, which I like to consider close to another coat of clear coat.
I’m not a professional, though I do own and operate a detail shop here in Connecticut and I am leaning more and more towards ceramic coatings despite a long time not believing in them. It just eliminates a lot of steps for me ; as I used to wash and decontaminate, buff, detail spray (to remove residue) followed by multiple different products for paint enhancement and protection, followed by a detailer spray for the show car finish. The enhancement isn’t always the most important to the customer, the protection is. And I wouldn’t do the protection without the enhancement. The ceramic coating seems to be more of the “All in one” therefore knocking off a couple steps for me.
Ceramic coatings are also growing to be a wider and wider variety with marketing tactics for hardness, longevity and performance. Stick to a good reputable brand and go with it.
