I agree with it making maintenance easier. It’s well worth the investment if you’re into detailing and cleaning your cars.I have always got my cars ceramic coated as it just makes general maintenance so much easier.
the one comment I would make is that the cost really depends on the standard of the original paint and the level of paint correction / prep work undertaken. This absolutely applies to brand new cars. My GT4 (porsche) which most would agree as one of the best factory standards of paint and was trailered to the detailer had nearly three days of prep before the ceramic coating was applied and then the car was left to cure for a full 24 hours. The difference was night and day.
Also remember not to touch the car (clean) for at least 7 days after the coating is applied to allow the coating to fully
my formentor was in very good shape to be honest. I only Clay bared my car before applying the coating, washed it Saturday for the first time and the beading was great!
