To the OP, Sorry to hear about your introduction to M2 ownership, carbon roof failure is certainly a major concern. Hopefully it’s sorted correctly for you.
9 out of 10 wet footwells are caused by a leaking windscreen seal, so for peace of mind it may also be worth checking the screen hasn’t been replaced at some time.

Kind funny that people got ppf to protect car only to have it be even worst than rock chips when you take it off. |

EDIT: Let me correct this statement to clarify. Factory paint is applied under the best of conditions, and most times heated directly afterwards to promote bonding. Beyond that, the vehicle will normally sit for quite a while before getting into the hands of the dealer, which is usually the point where PPF may be applied (sometimes it's at the port, like it was with my Lotus-branded PPG Starshield). This process almost guarantees that the paint will be fully outgassed of reducer, hardener, and catalyzer before PPF is applied, and as long as the remover removes it correctly, will not cause an issue. However, it is possible that PPF can be applied to factory paint before it has fully outgassed, and therefore the condition exists that it could come off with the PPF removal, even if done correctly. However, I would think that would be a super rare instance. Last edited by ///MPhatic; 11-01-2023 at 12:53 PM.. |

not a ppf installer but I did just see that Matt Farah from the smoking tire was having the ppf removed from his new nsx and paint came right off the bumper, had to get it repainted. I would be very surprised if he used a bad installer, he is good friends with Larry from ammo as well.

I know that usually there isn't an issue with PFF on new, factory paint because the cars sit so long before they get to port or the dealer that full outgassing has occurred. Maybe Acura is putting the PPF on themselves? I know some manufacturers are now offering it. No matter how good the paint is, factory or not, it has to outgas fully before PPF can be installed, otherwise the reducer, hardener, and catalyzer get trapped and break the paint down, causing it to be very brittle. It doesn't even look like paint at that point, more like colored tin foil. |

Are applying new PPF in its place. If not I’d consider keeping it. The width of the rear arches causes them to pick up a lot of debris from the fronts. The PPF sections included in the stock setup seem to be strafiy located in the prime strike zone for rocks and other road nasties.

The area marked in red is what gets chipped up, but I did the area marked in yellow because I didn't wanted the PPF cut lines to be more hidden. Of course, I did the full rockers, full front, a strip on the roof, and the bottom of the door, etc, but this pic shows what I did in that area. |

It's also possible that the windshield has been replaced and wasn't sealed properly. This is common problem with replacement windshields.

If the water is in the passenger footwell, it is probably whatever is causing it on a few other M2s and F22s. I don't think it would be the windshield but it's definitely a mystery. I just hope the OP reports back with the findings. Unfortunately I have this sneaking suspicion that the issue is unrelated to the roof, but they did discover a roof defect in the process.

What's the issue with water in the footwell? It's it because of drains getting clogged under the hood and trunk?
