Corrosion under PPF?
Discussion
Long time lurker here - Hoping someone can provide a bit of advice before I get back in touch with the company which repaired the car.
Background, car professionally repaired (NSR quarter and bumper) after an accident in 2016. Corrosion began within a week on wheel arch lip. Car was returned and corrosion was rectified (body shop explained they were having issues with their compressors and moisture control?) When redoing the repair on the NSR quarter, the OSR was damaged in the body shop and was repaired FOC at the same time as the rectification work on the NSR.
The PPF was removed and refitted by body shop on both sides. When washing the car today I found what looks to be corrosion starting along the edge of the PPF and paint crazing at the top corner.
Is this corrosion or could it be something else? I can't understand how corrosion could start here as its protected by the PPF unless the clear coat was damaged when fitting or it has been a poor repair - or could it be something as simple as dirt stuck behind (I tried running my finger nail along the edge and PPF seams completely sealed and not dirt came off.) I didn't want to remove the PPF in case the clear coat was damaged and I made it worse. The rest of the car is completely corrosion free.

Photos of original damage, repair bill was approximately £3500 through insurance (no hire car, but did include 1 wheel refurb) so it wasn't a cheap job and it was completed through a well known company.
Thanks in advance

Not that it’s essential; but was it through insurance and an AM approved/preferred body shop?
If so, I’d go back through the body shop for them to do an assessment.
Even if not, I’d do the same; gives them a chance to rectify if there’s a chance they were at fault again. However, 6 years is a long time, so if corrosion, it could be new.
Assume the original work had only a 12 month warranty? Any remaining AM bodywork warranty remaining?

It was an approved Aston Martin body shop when it was done, but I don’t think they hold approval now, I think they’re purely an Aston independent now. Insurance paid for it, I chose the body shop as I wanted Aston approved (3rd party covered all costs as it was no fault)
I completely understand it’s a long time ago, but I can’t understand how corrosion could start there by itself? Seems a strange place and same both sides, I’d understand if it was the wheel arch lip, but puzzled by this one.
Thanks I think I’ll taking it back to them to assess is a good plan, just wanted a bit of advise so I have a rough idea of what it could be.

I’d agree that looks to be dirt ingress.
If the plotter used to cut it isn’t set up well for the film, or has a worn blade/platten, it’ll often leave a rough edge with some exposed adhesive and tiny torn bits of film.
These bits usually form the weak points that the film can start to lift from.
Whether you get any joy from the body shop, I couldn’t say.
It’ll depend on whether the film has any sort of manufacturer warranty, and whether it’s been installed by an accredited installer if the warranty requires it.
One final thing to take in to account is how long there was between the respray and the film application.
There’s often minimum wait times specified and solvent gas-off tests to be done to make sure there’s no reactions between the paint and film adhesive.

Thanks for the replies.
I believe it was precut “Aston Martin” film, I think it had a part number when I saw the invoice.
It would have been applied within 24-36 hours of painting, I remember it being a quick turn around second time round.
I’m guessing if it’s dirt ingress I need to remove and replace?

It’s either that, or live with it really, yes.I believe it was precut “Aston Martin” film, I think it had a part number when I saw the invoice.

Make sure to tell whoever you get to remove and replace the film about it being applied soon after painting. That way they can give themselves the best chance of taking it off with no damage to the paint.
