Are there any disadvantages of removing the factory undercoating from the engine/transmission/heat tubes, etc?

While under the car updating suspension, I have begun removing the chunky, dried oatmeal from the underside...what a PITA but results so far are nice.


Does this effect value (non-factory mod) or function other than perhaps sound insulation?
Thanks in advance.

Do a search. There are a number of sickos out there who have done magnificent things on the bottom of their cars with cleaning that crap off. Larpy and others--unbelievable stuff!!

Search using the term "cosmoline".

I have seen some impressive work...but am behind the power curve since I just took delivery of the car a few months ago.
After playing with new cars the past ten years, I forgot how messy and nasty used cars can be. SO tempting to just start from scratch, strip down to body in white and media blast/powder coat every single part...I am simply everwhelmed at the crud every where I look. Wheelwells are finally in check, but made the mistake of removing the transmission cover and just about shat myself.

-Had to go open and close the door exactly five times to make me feel better.

That is what it was, sound insulation. You will save a little weight, and loose a lot of sound deadening. And it's is a real PITA. It is best done on a rotisserie with a bunch of dry ice.

Please.

It prevents corrosion...why do you want to remove it?

The few already mentioned if you drive on salt covered roads in the winter or live next to an ocean.

The only advantage is it makes wrenching on the car more enjoyable.

The body was hot tank galvanized for corrosion protection. It was for sound deadening, although it may help preventing corrosion it wasn't really what it was there for.

The car will never see salt or winter roads under my care...and with a carpeted garage on the way, seemed like the thing to do while I have dirty floors and the ambition.

I will proceed witht he links provided.
Thank you all.

Hi There

If you mean the thick underseal on the floorpan of the car then it is a nightmare to get off. I removed it from the front luggage compartment floor. Rust can (and did) get under some of the underseal and you cannot see it until the underseal is scraped away. If there is rust there the underseal will come off easily. If not it will not.

If you mean the air tubes that run up the side at the back, then a crystaline wax is very good for protection. Will also work on any alloy parts, so suspension arms for instance. The British museum uses a lot of the stuff on exhibits and statues etc both indoor and out.

For the crankcase and similar I was told that Porsche spray the 997 cases with Tectyl. I used Tectyl on my suspension components and plan on using it on my engine after I have had it out later this winter.

Bad plan as a carpet holds moisture. You are better off using non-slip tile.
