Hmm, I would be skeptical at that price point. Ceramic coating takes several man hours to apply. And the ceramic itself costs begin around a hundred dollars or so. That price to me suggests a good surface prep and then a coating with one of the new ceramic sprays. The sprays have much less of the ceramic material suspended in a detail spray that’s much easier to apply and leaves a glossier finish. The difference is in a) the price is usually $15-40 for 12-16 oz of spray vs $100+ for 1.7 oz of ceramic (if it didn’t come in a small glass bottle like below, it’s not a true ceramic coating) and, b) the endurance of the coating. Most sprays realistically last for 1-3 months and a true coating can last for years; some even advertise 7-9 years.
The starting condition of the paint, what the vehicle is, and used for goes into my decision making process re ceramic. @TGS is 100% correct in his statement above. What I would add is the main benefit of ceramic is that it builds up a layer of ceramic between the paint and everything else. It’s very hydrophobic. The significance of this is the bird poop, sap, etc doesn’t stick to the paint. So you can rinse the paint off with water and the crap sheets off with the water. Ceramic makes washing the car muuuch easier. It’s a game changer for black vehicles. I had my F-150 coated and it sometimes looks freshly washed after it rains.
I think for most vehicles the spray is the way to go. I use the spray and a ceramic car wash on the wife’s Toyota. I shouldn’t have to reapply since the soap acts as a booster. It’s surprisingly a cost effective cleaning aid; I’m never going back!
