Really happy with the finish on my CX-30. Got Ceramic coat (Simonize GlassCoat) I bucket wash and pressure rinse when warm enough to hook up hose at house. But since it got cold, just blasting with pressure at carwash. High pressure soap and rinse, then low pressure 'spot free' and it looks like I spent hours. Been doing it every few weeks when I catch a day above freezing. Maybe tomorrow.
