I had my old 65 Coronet done. They done the full paint correction pollish and used Ceramic Pro brand coating applied. It was amazing. I am not sure of long term but I kept the car about a year afterwards and it still looked like it did when i had it done. They have a 1 year warranty, which is 1 coat, a 5 year warranty that is 3 coats and a lifetime warranty that is 5 coats. Must be inspected once a year by any Ceramic Pro installer for warranty. I will do it again when i repaint my Satellite in a year or 2.
