I have done some research on this subject. I DO NOT HAVE ANY FIRST HAND EXPERIENCE. Everything I share here is a distillation from the Internet from people who have used various products. So feel free to disagree or debate what is posted, I want to learn too. First some definitions: - Ceramic Polymer Coatings (CPC) is a liquid that is applied to the paint surface. Example product names are Opti-Coat and Cquartz - Paint Protection Film (PPF) is a clear film applied to the paint surface. Examples are Xpel and 3M products Cost considerations - the general consensus is that if you plan to keep a car 3 years or less, CPC and/or PPF is not cost effective. If you plan to keep a car longer than 3 years and then sell to a private party then CPC and/or PPF is cost effective. If you plan to keep the car longer than 3 years and then trade in to the dealer, it depends. Comparison CPC to PPF: CPC pros: - less expensive than PPF - generally brighter shine than PPF PPF pros: - longer lasting than CPC - more resistant to birds droppings, bug splatter, acid rain, road salt, and sand than CPC - resistant to rock chips, CPC does not protect against chips - more resistant to swirl marks than CPC Comparison of Opti-coat to Cquartz Opti-Coat Pro pros: - much longer lasting than Cquartz - tougher coating than Cquartz Cquartz pros: - less expensive than Opti-coat - brighter shine than Opti-Coat Opti-Coat Pro Plus: - the most expensive - all the benefits of OC Pro and Cquartz (except cost) General consensus: - Opti-Coat is more popular because vendors seem to be more reliable. Cquartz applications vary widely and there have been some unhappy customers. Opti-Coat customers are generally very satisfied. - Opti-Coat you get what you pay for, Cost for OP Pro is about $1K to $1.5K depending on location. It is possible to find a vendor for less than $1K but it is probably not a certified installer and it is buyer beware since a poor application is equivalent to no protection. - CPC will not protect against rock chips! - CPC does cut down on the need to wax the car - some car owners go full Cadillac and apply both CPC and PPF. These tend to be cars with value over $100K. - if applying both CPC and PPF, the PPF obviously goes on first with the CPC applied over the top of PPF. I am undecided at this point what I am going to do. If I take an early model 3, I may lease it for 3 years and then purchase a later model with all the options I want. Therefore I would not pay for CPC. If I can get the car I want in a year or so, I will wait and then purchase the car and keep it for a long time and probably apply PPF to the front fascia, frunk lid, and rocker panels and then apply a CPC over the whole car. And that's the way it is until I change my mind.
