A ceramiccoating is notscratch-proof, but can significantly reduce the possibility of swirl marks. A ceramic coating works by providing an ultra-thin but exceptionally strong and flat protective layer. It is hydrophobic, so it absorbs water, so it can be wiped dry with fresh microfibre towels with very little effort. Now you would think that, if the detailer knew what he was doing, all three cars would be swirl-free.
To know how to prevent paint swirl marks from forming, you have to know what causes them in the first place. This thickness, when combined with a flexible coating, can provide protection from the elements and abuse. There is a big difference between actually repairing the paint and simply protecting it, and ceramic tile is intended for the latter. However, what car owners and detailers need to be aware of is that ceramic coating does not improve the paint itself.
There is a misconception that applying a ceramic coating over a deteriorated paintwork is a quick and reliable solution. If installed correctly and at the correct thickness, the coating will dramatically improve the appearance of a vehicle and will outlast any other gloss enhancement product on the market. Compared to a band-aid type solution, this perceived "softness" leads to the misconception that ceramic is the key to fixing damaged paint. And because of this, coated AND sealed surfaces become much easier to wash, removing dirt with less effort and scrubbing and also rinsing much more water, which means less drying.
Hardness can help at some levels of protection, but on the scale of 1 to 3 microns, which is the average thickness of a coating, it doesn't do much directly. This applies to all types of tile products on the market, even those with "professional grade" on their packaging. Multiple coats after 3-4 coats can actually reduce the gloss, as the sheer clarity of the coatings is less than that of the quality clear coat. If you wish to correct paint damage, the vehicle should first undergo a polishing process before considering the application of a protective coating.
When choosing the right type of ceramic coating for your car, you should consult a professional to ensure that you are getting the best possible type of coating to suit your vehicle's needs. Most car owners apply a nano-ceramic coating on their vehicles to protect the paint against bad weather, debris, chemicals and more.
