Undercoating - OK to remove?

Recommended Posts

I recently bought a 2003 996 C2. Apparently, at the factory, they applied a thick undercoating on the bottom of the engine assembly. There's alot of overspray on other components too. This tan goop looks like hell. Can I remove it without getting into a warranty issue? I'm in California were severe weather/road conditions are not an issue, i.e, road salt, etc.

It's cosmoline, used to prevent salt water corrosion on its trip over. I removed it, as when it heats and softens dirt sticks to it.

You can remove it with an engine de-greaser, Einmann Fabrik makes a good one. You may also need some turpentine and brush in areas that have a thick coat. Follow up with Meguiars Engine Coat for protection ( it's a type of spray on wax)

That is one great looking engine !!!

Do you not get snow/salt in your area, or do you only drive in the non winter seasons?

02 blue, thanks

I don't drive it much in the winter, but the Meguiars Engine Kote offerers good protection from road salts and also give a bit of water repellent action. Even without the engine Kote (hose the undercarriage when you clean the car), I don't think you would have any problems and certainly will not void the warranty as it's a shipping protection coating.

I just couldn't stand the look of the brown goo mixed with sand on my engine and suspension parts
