Thanks for the share, I've got similar orange peel on my rear fenders, I've been afraid to wetsand. After seeing this, it gives me a bit more confidence to tackle.

Me too! I think I'll give my detailer a call and see what he says.

5yr old thread?

"paint bubbled due to hydraulic fluid from floor jack"

???

over the ENTIRE CAR then, I see?

"factory original decals"

with orange peel underneath them and that don't line up right, eh??

Martini Edition, huh?

Be the first one I've ever seen w/o the accompanying interior treatment

sounds like someone bought turd job GP white 930 and thinks it's a Martini 8-)

careful on wetsanding guys, it not terribly hard but I'd practice on not my 930 first... like... the wife's rig or something heh heh

If you guys are going to get your car wet sanded make sure that who ever is doing it is using a paint gauge to see how much or how little paint is left on your car. Remember there is no clear coat on these cars. Good luck

Couldn't agree more... I do my own waxing/claybar/washing. Anything beyond this - I would rather leave it to a professional. I wouldn't want to jack up my paint - these are too valuable.

It's all fun and games till you start seeing another color appearing under that wet paper.

Check with a restoration expert, "orange peel" on most early cars was the result of Porsche's inexperience with the underlying galvanizing process. There is a lot of discussion suggesting this "orange peel” resulted in many low mile 930 owners repainting their cars. Might have seemed like a great idea back then but too bad for a lot of otherwise nice 930's today. Repairing "orange peel" on a '70's 930 may be counterproductive to maintaining originality.

Spot on Paul! Better yet, original or a decent repaint, leave it to an expert - unless you don’t give a ***t about your car.


Heed what Hams930T and quattrorunner say. Original paint is only original once.

Porsche Metallics are two stage. Flats are almost invariably single stage. Cutting paint on base clear is easy. Single stage...better to shoot it right the first time.

For this tread, only talking about single stage (flats) on the 930. Applied at the factory, only a few mils thick. Naturally heavier in some areas than others. You only need to take a little off in the wrong spot to be in never-never land.

Two stage is a different story.

Some of the pictures this guy shows is not orange-peel, its solvent pop from the reducers or thinners in the primer and paint. I would say that this car has been painted or a least touched up in several areas.

Prrrrrreeeettycool!

BTW, my car started to develop orange peel about 15 yrs ago..., it began on the rear flares welds, then the front flares, then a section of the passenger door and just began on the roof behind the sunroof opening. At the Savanah Parade in 2011, I showed the car to the Porsche paint guru (German ???), he loved the car and told me DO NOTHING, that's real original single stage paint patina that, back then (1978), was totally unknown to Porsche. He mentioned that to "really get rid of it" you need to go bare metal... but the car would loose great value.
M2c.

Sounds more like solvent pop than orange peel.

Miguel,
Yes, that's the orange peel on the early 930 factory paint many could not live with and so they repainted their cars. Original paint examples are very scarce these days. Glad to hear you have one.



Paul,
Thanks for posing that eye-watering interior shot!

Misconception with this term, cars don't develop orange peel. The term refers to the finish as painted, typically from the factory (look at some of the later model Corvettes) or during the re-paint process. It is an effect of how the paint lays down. The car either has it or it does not..

If something develops later on, especially the timeline you describe, then it is chemical/bonding issue, or checking as we like to call it.

Solvent pop is usually seen on cars that have been repainted or touched-up as certain chemicals may have not been given enough time to fully dry/evaporate.


The German paint guru was correct in that to get rid of it you have to go pare metal. What you describe could be a paint reaction to lead over a period of time as a bare metal refinish will show metal finishing on seams etc.. on the early cars. No polyester fillers etc..

Yea, so much for those who think their early 930 has original paint ( many don't ). Not due to misuse just in the process of getting it right at the hallowed Porsche factory which was staffed by people in the learning curve of that time.
