Before applying the ceramic coating, it's all the time consuming work that was done to clean and then correct the paintwork.
Some deep washing that removes not only all the dirt etc, but also all the old 'layers' of wax etc. Then clay bars, a polish that was 'graded' from 'coarse to fine'. The ceramic coating simply goes over the top to protect what has been done underneath!
Costs depend on who/where/what/when etc etc! Best give a few places a call as I found the quotes were quite varied... from £800 - £2,100. A lot of money but for me worth it as all the swirls and scratches were really annoying me and I did not want 'another' detailer with a 'mop' having a go... which then removes even more 'clear coat' over the colour!
IF I was ever to buy a new Morgan, I would have this done before the car even hit the road. My car has been sat next door to some brand new Morgans and the difference in depth and shine is really noticeable. If you like that kind of thing!
