Ceramics will resist scratches to a degree. It will help prevent normal washing swirls, but not a key running across your paint. They will not protect you from a rock chip like a PPF will. They usually do not last more than 2-3 years.

PPF is by far the superior protection. But it also costs 3-4k to have it done right. It will still self heal with a ceramic coating on top. The ppf heals by heat.

you can do ceramic on top of ppf with no issues. it will help protect against UV damage with can yellow ppf over time. and make the car easier to clean.
