I have had the Z8 clayed a few times and the glass feeling of the finish is always awesome and lasts more than a year. I dont like to put wax on the car. It is always garaged and still is a beauty after 19+ years.
But my local auto detailing facility is offering Ceramic Pro 9H ( 1 to 4 layers ) along with a layer on the wheels which might be good considering that brake dust after each ride. They also suggest Rain on windshields.
I haven't seen any comments on Ceramic Pro since 2017 (on a post from the Netherlands). What experience has chat room members had with this product and how did you like the look? I understand they will first do a high end wash and clay the car before applying the H9.
