Well worth having the paint surface fixed first and then have the Ceramic Pro applied. It really does look amazing and it only needs applying every 3 years or so, subject to mileage etc. But the more layers which are applied, the longer it will last. Ceramic coating actually isn't ceramic but a polymer which bonds with the surface of your paint. Seems to be more effective than wax and certainly longer lasting. I had my QP done at 'Ceramic Pro North West' in Manchester. They did a fantastic job.
