I'm not convinced these ceramic coatings are worth the expense and trouble. Somehow the hype about how well they protect the paint feels like expensive snake-oil. It's not that I'm old fashioned, I'm all for modern paints and coatings, I've competed with my Porsches in multiple concourse events. However, I think a good wax and wash, paying attention to using quality cleaning methods and materials will do a superb job by themselves.
I think some people just want an easy and quick option and are prepared to pay for it which is far enough. My concerns would be what happens when you get some swirls etc as the only thing you could do then would be to use a da or rotary polisher which would remove the coating and also what happens once the ceramic coat gets to the end of its lifespan so like you I'm happy to use more traditional methods even though they take longer.
