Minimal maintenance: along with the protections provided a ceramic coated vehicle generally requires far less upkeep than a non coated vehicle, never wax again!
Acid protection: weather you realize it or not your car is constantly under attack (especially here in the south) by acid damage, this comes in the form of bug guts, bird poop, and other harmful elements such as spilt chemicals, gasoline, etc.
UV protection: We all know how easily the sun can damage things, your car is no different, UV damage from direct sunlight is one of the major causes of Oxidation and clear coat damage.
Water Spots and Chemical Etching: Ever wonder why you have spots left behind on your vehicle after washing or from rainwater, sprinklers, puddles, etc.? Water acts as a carrier for chemicals which are left behind on your vehicle after the water evaporates, these chemicals then start eating through your cars paint and do not stop until they reach metal. Ceramic coatings are resistant to chemical damage and help to prevent water spots.
Scratch and chip resistance: professional grade ceramic coatings create a much harder outer layer than your paint previously provided, this helps to prevent damage from light scratches and impacts.
Hydrophobic Layer: ceramic coatings become a hydrophobic shell on the exterior of your vehicle this causes water to instantly bead up and shed off of the surface of your car which makes washing an absolute breeze and also helps to prevent the depositing of harmful chemicals that would normally build up on your paint.
on top of being hydrophobic Ceramic coating positively charges the surface which keeps particles from being able to easily grab on or bond to the surface of your vehicle.
Ultimate Shine: ceramic coating enhances the gloss and depth of your car’s paint and greatly improves the aesthetics of your car.

​Common myths of ceramic coatings.
Ceramic coatings are indestructible: yes professional grade ceramic coatings are far stronger and resistant to external elements than a typical paint job or wax coating but much like anything else in this world that does not mean it is completely indestructible.
Paint scratches and chips: much the same as above ceramic coatings can protect from some light or minor scratches due to its added hardness it is not a bulletproof layer and will not protect from harder impacts or scratches.
Lifetime Warranty: yes many permanent ceramic coatings do come with a "Lifetime Warranty" no this does not mean it is covered for the rest of your human existence. The term "Lifetime Warranty" in this case is generally referring to the average span of time someone is expected to own one single vehicle. Where ceramic coatings are concerned a "Lifetime warranty" is usually around 7 years, be sure to ask your installer the length and terms of any "Lifetime Warranty" for your own clarification.

Paint correction is a industry term which refers to the refinement and restoration of your paint job.
Paint correction can come in many shapes and forms and be used in many different situations.
For example paint correction is not just for older vehicles with extreme signs of paint damage. Paint corrections can be performed on new vehicles with low or even zero miles.
What many people fail to realize is their factory paint job isn't refined after being applied to the vehicle, this means an experienced paint correction specialist can use various techniques such as, clay barring, buffing/polishing, or for some extreme cases wet sanding to refine the factory paint and enhance the clarity, gloss, and shine of even the newest of vehicles.
Paint correction minimizes or removes water spots, scratches, swirls, orange peel, and various other imperfections. the methods used are custom tailored to enhance each vehicles individual needs.

The term decontamination wash is common among detailers but may need some clarification for those not in the industry.

A decontamination wash is a multi step system used to remove any mineral deposits, chemicals residue, waxes, sealants, and various other contaminants that are present on even new vehicles. this process includes but is not limited to degreasing, clay bar treatment, iron removal, and a final hand wash and dry.
