Pinhole Blistering on Rocker Panel Undisclosed Respray? - Page 2 - Porsche General - PistonHeads UK

Hi all, I’m reaching out to see if anyone else has encountered this before. I recently purchased a 992.1 GT3 Touring from an OPC (Porsche Approved, clean HPI, very low mileage, no paint or accident history disclosed, and priced accordingly). Everything appeared fine during inspection — until delivery day… and it’s been unravelling since. What started it all: the wheels As part of pre-delivery prep, I asked for the wheels to be powder coated in Satin Neodyme. I was assured this would be done to proper spec. Instead, I received what turned out to be a poor spray job — the paint began peeling after the first wash, just 48 hours after delivery. This was confirmed by two independent wheel professionals and other GT owners: it wasn’t powder coat, nor anything close to factory quality. That immediately raised questions — because if the finish on something as visible and agreed was misrepresented, what else might have been? Then I spotted this on the rocker panel When the car was being trailered back to the OPC (to rectify the wheel issue and several others that developed in the first few days), I noticed a line of raised dots or pinhole-like blisters just above the textured coating along the driver-side rocker panel. It’s not stone chips. It’s a linear band of bubbling, which looks exactly like solvent pop, poor masking, or an uneven lacquer coat — all typical signs of a localised respray. The dealer insists this is “normal” and part of Porsche’s factory-applied stone-chip protection. But I’ve owned a 991.2 GT3 and inspected many other 911s, and I’ve never seen this on a clean factory panel. There’s also no note of this in the 111-point check, and no damage history disclosed. Why it matters If this is non-factory or undisclosed repair work, it materially affects the car’s value, provenance, and resale. At this level — and with full Porsche Approved backing — this goes beyond cosmetics. The dealership is now being pressed to carry out a proper bodyshop inspection using paint depth gauges and relevant tooling, but I’d prefer not to rely solely on internal assessments if others in the community have seen or experienced the same issue. Has anyone else seen this bubbling/blistering finish on a factory rocker panel on a 992 or GT car? Would hugely appreciate any insights — especially from experienced owners, paint professionals, or anyone who’s dealt with this type of scenario. Thanks in advance,

A picture may help ...

Sounds like the OPC/someone has used a smart repair man in a tent to do the wheels and touch up a mark on the body Been, there done that, with a 6 month old 911 from a Porsche dealer that honestly looked like the rear bumper had been painted by a blind man on a windy day. It was awful. When I pointed it out they agreed to re-do it in their approved body shop.

Cheers mate, just tried, and it worked on my end, however, as a new user i am not allowed to post links within the 14 days period....

Sounds about right — though the dots look very consistent, running along the line between the door/rear quarter panel and the lower painted rocker. Apologies I can’t post photos here, so a verbal description probably doesn’t do it justice.

Thanks, mate — I think it’s just a new user restriction; I’ll need to wait 14 days. I’ve posted the same content over on Rennlist, where there are no limitations — including a photo in case you're interested.

Not having a go at all smart repairs. I have had excellent work done on two of my cars in my drive. However, the job my OPC did (in a tent in their car park) was truly awful. And sanding, filling and spraying wheels isn't the same as a proper dip and powder coat. Fine for a spot repair but a colour change? No thanks. Edited by anonymous-user on Sunday 6th July 18:52

Here you go buddy

I recently watched a Mat Watson video on youtube when he picked up his new 911ST. The first thing he did was take it to a paint correction facility. Here they pointed out how poor paint work was on a 300k car. Apparently Porsche are better than most! This probably doesn’t answer your question, but maybe makes the point that the quality of paint finish when one of these cars leaves the factory may be not to the standard you might expect.

Edited by Discombobulate on Sunday 6th July 18:52 I think that’s exactly what happened with my wheels too — sounds all too familiar. I won’t even bother posting photos here (still too new to attach images), but honestly… they looked awful. I’ve done a better job painting a flower pot! 😅 Really disappointing, especially coming from an OPC that specifically promised a proper powder coat. Unfortunately, that set the tone — once the wheels failed and mechanical issues started appearing in the first few days, my confidence took a hit. It’s hard not to grow suspicious of everything after that. Interestingly, I’ve had a mix of replies on my Rennlist thread — some saying the bumps on the rocker panel are “normal spatter from undercoating,” while others with the same car say they’ve got nothing like it on theirs. So I’m still trying to get to the bottom of it… feels like a bit of a coin toss at this point.

scrounger73 said: Here you go buddy Not acceptable IMO. I had a 1989 and 1993 Nissan 300zx with stone chip protection like that around the bottom but absolutely none of the isolated blistering that your picture shows. Don't accept that. Better paint on my 2015 Astra.

Is that a masking line on the left section at the bottom?

Edge of the PPF ?

I’ve seen a few cars over the years at OPC that have had some form of paint issue/ respray. The worst was from an Audi dealer’s when I got a 16 month old RS4 - about 4 months into ownership all the lacquer started leaking off the bonnet! Buy a paint depth gauge and go around the car you’ll soon know. It wouldn’t stop me buying a car though , if resprays/touchups have been correctly then there should be zero issues. However knowing that they are done and having in writing an agreement with dealer that if they fail then they will do something about it is a good idea.

Hope you had it sorted! The OPC send me pics of the readings of the paint depth for that area (though above the bumpy areas, more towards the bottom of the door panel), as well as other areas, all seems in the reasonable range. I am asking them to take readings at exactly where those blisters are and see if there is anything new there.
