Shouldn't use WD-40 for locks or door seals. false hope & waste of time.

Vaseline jelly for seals (or spray of PAM every few days, don't use butter flavored unless you want cats & dogs sniffing around)

liberal use of graphite lube for locks & latch

Yes, and it also comes as a foam sticker, which avoids most of the mess.
The silicone is quite effective for the seals, one treatment will often be enough for the winter season.

Of course, when the car is already solid frozen, it is too late.
I know a lot more about that than I would like to.

And you can get all sorts of oil or chemicals to fill into locks; actually how good or bad this is I don't know, but our friend from Alaska and at least one more here had some interesting comments on WD-40.

I think the 928 is better in the cold than the Cayman, at least when it comes to frozen doors.
The Cayman has frameless side windows that is automatically lowered about half an inch when you open the door, this is of course asking for trouble when the side window is unable to move due to snow and ice.
I guess they only have dry, cold snow in Stuttgart, and summer all the rest of the year, no fall or spring.

 

I guess the Porsche engineers are shocked to hear that Cayman owners do not keep their Porsches in heated enclosed garages.


Last I heard, WD-40 was 'designed' as an electric contact moisture displacer. How it became the lubricant of choice must be due to great advertising.

Heard that silicone lube is good for the seals. Oink oink oink . . .
Did manage to tear my ex-Audi's door seal before I knew about silicone lube and such. Grew up in Hong Kong. Only thing that froze was the ice cream in the freezer.


Okv, I'm not even attempting to pronounce your name.

 

Used to live in Northern Indiana. If it was wet, and going to turn cold overnight we would shut trash bags in the door where it seals.

 

damn, its 75 here today. whew.

 

There has to be a way to disable the windown down option. Maybe the owner's manual has something on this.

As for the WD-40, it was designed for water displacement (Water Dispalecement formulay # 40) to be used on I think Atlas missles (ICBMs) stored in underground silos (sp?).
