A ceramic coating is a very powerful environmental sealant that replaces waxes and makes maintaining your vehicle much easier than any other means on the market right now.
Ceramic coatings excel at environmental protection, i.e., things like water spots, dirt, bug guts, and road grime are going to be a lot easier to deal with and wash off of your personal vehicle. Additionally, they give an incredible amount of gloss and are very easily recognizable on a vehicle simply from the incredibly high shine.
If you want your vehicle to look its best, nothing is going to compare to a ceramic coating.
However, ceramic coatings aren't without their limitations. While they give you that incredible protection, ultimately, it is a liquid sealant. And as a liquid sealant, it is not going to protect your vehicle against scratches, rock chips, and other road debris. You're not going to find that your vehicle is immune to that kind of wear and tear. If that is your goal, you may want to consider paint protection films to protect the most vulnerable parts of your car, and then look at ceramic coating the rest of the vehicle. You can then come on top of that paint protection film with the ceramic coating to lend that paint protection film an incredibly high level of hydrophobic properties and making it easy to clean as well.
So having said that, is a ceramic coating worth it ? Absolutely! everything about a ceramic coating is amazing! Your vehicle will be crazy glossy, and extremely easy to clean. It is, indeed, an excellent solution to keep your vehicle looking brand new for years!
