Default PPF and/or Ceramic Coat?

I recently purchased a 2019 991.2. It had PPF installed on the front when new, it has very low miles (2K) and it looks great. Should I now consider Ceramic Coat on the back and/or PPF? I believe the most common approach is the do a Ceramic Coat over the entire body, then PPF the front, but what would you recommend now? I don't plan to remove the PPF on the front at this time as it's working well and looking good. You don't Ceramic Coat over PPF, do you? Will consult with a pro, but wanted to check here first. Please advise. Thank you Rennlisters!

"You don't Ceramic Coat over PPF, do you?"

Yes you absolutely do.

I just had my 911.1 covered with PPF (XPEL) and then I applied Kamikaze Surface Film Coat. It went on very easily. The video on their website is very helpful. My 9 year old black car with 57,000 looks like it just rolled out of Stuttgart! Not a scratch or swirl in sight, beautiful high gloss shine, and it the ceramic coating makes it super easy to keep clean.

Ceramic coat over PPF. Not the other way around.

Thanks guys! My M3 already has a recent ceramic coat. What happens if I want to PPF the front? Is that okay?

I picked up a 991.2 a few months back with 19k miles, has factory PPF in the front but both the PPF and paint are showing some light swirl marks in the sun. Plan to have a pro remove the PPF, do a full correction, then apply a better PPF in the front and replace OEM stone guards, and do Feynlab ceramic (it self heals) all over.

A high quality ceramic coating on the whole car, wheels and calipers will make maintaining the car much easier. You can do this yourself if the paint is in great, polished condition. If not, the 1 step polish would be good.

Paint correction, PPF, ceramic coating.
Did mine two years ago and it is still mostly perfect. Took it to my detailer yesterday for a look over as I have a car show at my marina next weekend. He is going to do a refresh on the coating and then some other minor corrections including some interior leather repairs and wrapping the chrome window trim with a black film. Going for the trophy!

There are excellent hydrophobic films now that make ceramic unnecessary. I had my rear bumper done in STEK Dynoshield as a test for the rest of the car (still has the original clear film that the first owner had done for the front end).... this hydrophobic film is unreal. Extremely clear and slick looking. Water beads like crazy, and its self-healing, too.

Apparently still not permanent though -

"Longevity of the Gentoo coating will vary based on environmental factors, abrasion, chemical contact, etc. In general, it should last well beyond five years in an indoor environment with no abrasion. Outdoors, it is likely to last 3-5 years depending on the conditions and application."

Yeah, none of these solutions are permanent unfortunately

I never understood PPF... To me it's the automotive equivalent of grandparents leaving plastic wrapper on the sofa to keep it nice. I bought this for me. I'll rock chip the $hit out of it if I want to- Ok not quite, but if it happens so be it.
I'll have the hood and bumper repainted for a grand if it gets really bad... The ceramic coating on the other hand, I do get: water beads, I need to wash less..Cool.
Mind, I'm not saying PPF guys are wrong, it works great, to each his own... I'm ok with a repaint if necessary - espeically on a clear car, I've seen PPF go nasty on clear colors - supposedly modern one does not... On a black car that makes sense.

Greg, just drive the sh$t out of it and repaint as needed. It’s just a car for Christ sakes. For those that disagree with this philosophy, have the car polished and PPF as much as you want and then coat the whole car. And then enjoy the sh$t out of it. Cause it’s your car and it’s protected.

Have the 911 ceramic coated all over. The M3 cannot have PPF over ceramic coating. The coating is so slick, the PPF won't adhere properly.

BTW, very nice 911.

3.5 years and 30K miles in and I have driven my car like I stole it. I put tires on the roof, in my back seat, and hammer it the best I can on the track. PPF in front of the rear wheels, at the front of my car and in a few areas where folks decided to drop something on my car, is really beat up. Below is almost perfect paint so I can replace the PPF and have essentially a brand new looking car. PPF gives me the freedom to care a little less but still keep the ride beautiful. May replace with stealth PPF so I have a new look.

It is just a piece of mind thing for me. It does not crinkle like my Grandma's sofa, so it is not exactly the same. I miss Grandma...
