While looking at a used 07CS at my local dealer last week I got to chat with the mechanic fidling with the car and mentioned to him that the car did have some salt spray under the engine compared to other cars on the lot. He happened to mention that these "older" models have the undercarriage sprayed (cosmoline?) whereas the new ones are coming in without it and they're seeing them rust quickly.
Is this true, or was the mechanic essentially helping to push another sale? I did a brief Cosmoline search on this board and didn't find any posts confirming that new Porsches aren't being sprayed anymore and engines/undercarriages have become more prone to rust.
:thanks: for your help!
Don't know about that. My '08 (delivered in Nov of '07) had cosmoline overspray on two of my rear wheels. Finally got around to removing it earlier this year!
My '08 also had Cosmoline. Maybe the prior owner drove the car in the winter on salt roads?
Thanks for the replies, I'm not doubting the previous owner driving it in the winter, that or the dealership drove it around recently as we had just had a bit of snow come our way too. I understand this coating helps prevent rusting of the undercarriage and engine/drivetrain components.
What I'm questioning is why would
Porsche
stop coating their cars on the newer (2009, 10, 11) models, a cost saving measure perhaps? Again this info came from a P-dealer mech, but I'm questioning its accuracy.
Curious as to whether this threw off the balancing of the rear wheels?
This would be a giant cost cutting measure if true. Unless cosmoline was superseded by a better rust-proofing process.
Cosmoline is sprayed by hand at the factory for cars shipped overseas.
It is no longer applied to cars made in Germany.
And yes, they use salt in Germany.
Being made of alloy metals, the components of your
Porsche
will not rust with the Cosmoline removed.

James is right as far as I know ,I use to work at the docks in San Pedro Calif removing Cosmoline from the cars comming from Japan .I Had to wear an acid suit that resembled a huge mop and just go over the whole car with my mop body suit ,the next guy had a high pressure washer with deionized water and sprayed the car down .I was told it was put on the cars that were shipped overseas on ships to prevent them from rusting or starting the rust cycle from the heavy salt water and air. once they got to the US we removed all the Cosmoline for dealers that did not want to do it themselves.
It was a horrible job . we often worked 24 hours straight through the night when the bosses put 100 dollar bills in our hands to keep us going .
the smell was horrible ,no one would go near me
I still have nightmares of that hedious job ,The head boss use to run around saying we were at disneyland:crazy: he was later put away

You made my day Dave ! happy new year to ya
my 06 had cosmoline on it, but thats protection for the boat ride to NA. the reall rust protection in the Every current
Porsche
, in fact, uses 100 percent galvanized steel for its monocoque. Galvanized steel is sheet steel that has been dipped or plated with zinc, acquiring a molecularly bonded coating on both sides. It has two interesting properties: First, its electrochemical characteristics cause the zinc to “migrate” to any area on the steel plate that is scratched — a metallic healing process. And second, when welded, the zinc condenses on the welded area, protecting it nearly as effectively as if it had not been welded. Galvanized steel is the first — and most important — line of protection for
Porsche
bodyshells.
