I'm having my car professionally cleaned and they have an add on service of putting nano ceramic coatings on the car after they are done doing all the other stuff. From what I can tell, it protects the paint but is it worth the added cost if they are doing the clay, polish and waxing?

 

Judgement reserved on whether it's good or not and so much weighs on the detailer's thoroughness in doing the application.

I personally detail my black car once or twice a year as I am garaged and feel more often is not necessary.

Here's a link to some info to consider before you commit: http://www.drbeasleys.com/blog/2014/...ersible-error/

 

Most of these "coatings" are sold by dealers on new car prep... its a easy way to pump up the delivery costs .



Good maintaince of your stock paint will last as long as any "aftermarket coating". Wash it weekly, clay bar and wax at least every other month depending on how bad the weather, roads ect are in your area is all you need to do. Ive taken to also keeping a few microfiber cloths and a bottle of spray detailer and spray wax in the trunk and sometime mid week Ill wipe it down and a quick spray wax. Takes 15 min to do the Sonata and keeps it looking clean all week
