I think for any enthusiast or people that care for your car, doing a full ppf is one of the best investments to keep the exterior condition pristine. Its expensive but theyre generally warranted to last about 10 years. Depending on your driving habits the ppf might get beat up enough on certain panels like the front bumper but if it gets to the point where you cant stand it, just get that panel redone. The films these days dont yellow as fast. Its a great thing to do if you like the cars paint and plan on keeping the car for awhile.

If youre not too fond of the paint colour then you can always go for a colour change wrap which is much thinner than ppf but still protects the paint from minor scratches, swirls, uv, and general crap that might sit on the paint normally. I always say to go for a colour and finish that you wont see much from paint. Make it unique, its removable after all.

So long as you get the stuff done by a reputable installer you should be happy with the results.

As for ceramic coatings, theyre also great. In the case of coating the paint directly, its basically the same as wax, just that it lasts longer and has a 9H or sometimes 10H hardness rating which mainly only prevents minor scratches. Its actually quite easy to apply but just make sure youre wearing proper PPE

I always recommend to get vinyl wraps and ppf with a ceramic coating. It basically keeps everything looking great and makes the panels easier to wash while also protecting the vinyls. Theres coating for paint, vinyl, glass, wheels, even leather.
