    Re: New 997s brown/black coating on engine

    I think it's a cosmoline type of protective covering.

    I believe the factory does some selective coating to inhibit corrosion during the ocean crossing.

    At least that's what I've been told.

    Most likely can be removed w/ some sort degreasing agent.

    That's what I hear too.

    Just leave it alone. It will burn off or dry off or whatever: not worth your time to even be concerned about.

    997s brown/black coating on engine is Cosmoline

    With a pressure washer, some mineral spirits, and a little elbow grease, it will come off, and your underside will look like this:



    It is best to remove it when it is fresh. Cosmoline does not burn or wash off, it will just bake on, and after a while it will be almost impossible to remove.

    I know this is off topic a bit but I'm looking at your picture and it appears that your car is in a state of suspended animation. I don't see jack stands or lifts. Am I missing something?

    BTW: Love your undercarriage!

    It's magic... I was wondering the same thing.

    It's a troubling fact, since ca. 1978 (specifically the TIME magazine cover of _retouched_ Egyptian pyramids) photographs can no longer be routinely relied upon to tell the truth anymore.
