I bought my car 6 years ago and the agent told me they had a promotion for car coating and tinted windows  I didn’t know about coating but took the offer as agent told me car would be easier to wash. I didnt wash car regularly and sometimes for a few months. As a result, the are water marks on the car even with the coating. I still don’t regret. Coating keep the car shiny especially after washing. The watermarks are only visible if you are near and look for them. Coating cost about the same as repainting but you got a shiny car all the time whereas for repaining, your car is dull all the time until you repaint. I am planning to recoat my car again and this time would try the carwash2u.
