No. Ceramic coating does not make vehicle paint scratch-proof.
It also does not make a car stone-chip-proof, prevent every swirl mark or provide permanent protection.
What a properly applied coating can do is add a useful protective layer to prepared paintwork, improve water behaviour, make routine cleaning easier and help maintain the appearance of the finish.
Understanding that difference is important before deciding whether a coating is worthwhile.
What is a ceramic coating actually doing?
A ceramic coating is applied to the prepared exterior surface of a vehicle and forms a bonded protective layer.
Once correctly applied and cured, the coated surface typically becomes more water-repellent and easier to maintain.
Water tends to bead or move from the surface more readily, while dirt may be less inclined to adhere as stubbornly as it would to unprotected paint.
This can make regular washing more straightforward.
A coating can also enhance the appearance of properly prepared paint, particularly its gloss and clarity.
The important phrase, however, is properly prepared.
