What's that gunk under my car?
 

When I installed my exhaust system I noticed the castings under my car looked like they had some kind of protective coating sprayed/dipped on them. What is that stuff? Does it come off? I imagine the detailed underside of a 996 must look pretty awesome. Anyone ever get that board?

mostlikely cosmoline

it's cosmo!

Why is it there? Does it come off? Well, I'm sure it comes off, the question is how and how much of a job is it?

"Your neighbor?"....... Time for roll-call!!!!!!!!!!

Its just a coating to protect the underbody fromt he factory...

Helps against rust and the elements...

you can use "oil flo" to remove it.
get in touch with larry reynolds of carcarespecialties.com (?)

I hated it and got bored enough one weekend to attack it. Oilflo safety solvent and small brushes. A very messy job but worth it to me :cool:

Wow.... Talk about a bored man... :) How long did that take????

Nice photos, maybe you can consider selling them to Oilflo safety solvents...:D

If you want to know where to get your own Dr. T provided this information to us last year......... ;) Did someone say group-buy? hilarious

Yeah!! What he said!!
Looks amazing!!

Dr Toothbrush, that is some dedicated Concours work!

Wow, what a huge difference that makes. I wonder if there is any downside to doing this...

If you live (and drive during the winter) in an area where the roads are salted I think I would leave the cosmoline on for some added corrosion protection. However, AFAIK Porsches in Europe don't have the cosmoline applied so I really don't think it would hurt not to have it and still drive in the winter..

Interesting...
