I know, I know, ANOTHER freaking PPF thread in the 991 forum.

I just had to put a little cleaner wax (synthetic) on a little portion of it due to some hard water spots that weren't easily coming out. Is there any aspect of element to PPF that can harm? I know cleaner wax is an abrasive that can "strip" clear coat, but at the end of the day I assume since PPF is plastic, as long as it doesn't eat through (which would never happen) it should be fine?

Call or email the manufacturer of your specific PPF & ask. (XPEL, 3M, Suntek, etc.)

So turns out the cleaner wax I used has petroleum, which is supposed to be a no no on PPF. I guess my wonderment/paranoia is whether using it this one time can cause premature degradation of the PPF. Or if it'll wear down some protective coating PPF has. So far it looks totally fine and normal.

The BIGGER question is why are you getting hard water sports? That needs to be resolved, too. What you already did, is done. Don't worry about it. Move on. Next time, use something less abrasive. Less is best. Then work up if needed. Sounds like your PPF needs a good cleaning/decontamination, and sealing/coating.

Long story. The PPF is actually in really good shape, which is why I'm concerned about prematurely diminishing it, but there was a pipe leak above my car that I didn't dry off in time (probably the only time I didn't get immediate OCD about water on my car) so it etched like sprinkler water that dries up does. The cleaner wax took it right off of the paint and PPF, but I may have rushed with the PPF (i.e didn't think to check if said wax had petroleum) because I wanted to be sure to get the spots out.

The wax is obviously sitting on the PPF but of course the residue was buffed out. Has anyone ever used a petroleum product on PPF and seen it go the distance without yellowing/etc.?

K-A, we have a lot of very good info in our dedicated Concours Forum, here's one to get you started:

I don't get it.... I have had PPF since 2006 on 4 cars and used Collinite 845 insulator wax and never had an issue.

That's the best wax I've ever used before switching to ceramic.

But it contains petroleum products... My PPF looks brand new. My 997 had PPF since day one (2006) and looked brand new when I sold it.

I used the wrong products on mine a few times. 4 years in and no coloring.

I cannot give up on using Collinite, I just can't.

Yellowing of PPF and wraps comes from carnuba wax, which is yellow. Most all synthetic waxes and coatings are cut with petroleum distillates. Just avoid any with carnuba.

I thought the yellowing comes from the PPF glue, which ages over time. I also though that you treat PPF like you treat paint, so putting sealants, wax, etc was just fine. Been doing that for years on mine with no issues.

Yes - Half a dozens times but not like on a weekly basis.
