I’m just your normal “cuci + water wax” guy, so cannot comment on ceramic coating. But from everything I’ve read on the highly informative Care Care & Detailing thread on this forum, all PPFs, no matter what price or marketing promises, will yellow over time. If that’s true, then PPF is probably the worst choice for a white car.

Agreed. If you normally wash your car once every couple of weeks, you will still need to do the same even with a ceramic coating applied. From what I’ve learned on the Car Care & Detailing thread here, coatings will not magically make your car maintenance-free. It will simply make your regular maintenance easier. Maybe without coating you would need to apply pre-wash first to loosen grime, but with the coating you can just rinse and go straight to shampoo. That’s the main benefit. Some people say coatings also have UV protection to protect paint from yellowing (especially for white cars) but I’m not sure how true that claim is. Also learned that, if you’ve coated your wheels, need to be careful at carwash shops and make sure to tell them not to spray that rim cleaner liquid. The soda content will supposedly kill the coating.

As for PPF, I don’t have enough knowledge to comment. Some people say the protection from stone chips is good to have, but others say it doesn’t really offer much protection and all the self-healing promises are just marketing. They also say PPF will eventually yellow and sometimes even crack and damage paint, and you also have to be careful when using a pressure washer. I was once tempted to PPF the door cups, but now I think I will just buff out scratches once every year or two.
