The ultimate protection for your paint is a combination of paint protection film and ceramic coating.
The PPF will protect against scratches, chips, scuffs, and other mechanical damage. The ceramic coating will add protection against UV rays, heat, salts, brake dust, industrial fallout, bug guts, bird poop, tree sap, cement, and road tar and other contamination. The ceramic coating will also do a better job at beading off water due to its hydrophobic properties.
These bond together perfectly - the ceramic doesn't crack or interfere with the self-healing properties of the film.
Paint protection films can dull the finish of the clear coat by some amount. Adding a ceramic coating on top will restore the wet glossy finish and make the film practically invisible. On partially wrapped vehicles, it's especially beneficial, as it will blend the surfaces together and restore a uniform shine.
If you're already paying the price for a paint protection film, a couple of hundred dollars on top for a ceramic coating makes perfect sense.
On partially-wrapped daily driven vehicles, you can substitute the traditional liquid ceramic coating for a Ceramic Spray coating that you can install yourself. It'll save you some money and give you amazing protection and a glossy finish on a budget.
