Removing Cosmolene

I'm getting an '03 Porsche Turbo in January and am debating whether to remove the cosmolene undercoating Porsche uses on the bottom of it's engines to protect them from rusting on the boat trip over from Germany. Have others removed this stuff? Is it difficult to do? I bought some Eimann Fabric Engine Degreaser to use for this which I read somewhere will work to gently remove cosmolene without being caustic.



My current plan is to wash the car myself at the dealership once it comes in with P21S, inspect the paint/body carefully for delivery inspection. Drive home, use P21S GEPC, dawn wash, 2-3 coats of Z2 w/ ZFX.



Wondering if I should bother with the cosmolene removal once I get it home?
 
On all the cars I've seen with Cosmolene on them (VW, Audi, MB, BMW) it all tends to come off on it's own during warm weather, on MB/BMW I usually see it fall off in chunks, on VW/Audis it seems to melt off .. I just got a 02 VW GTI and when I have my heater on it smells like I'm burning a candle (waxy smell).. so I know all of mine hasn't come off... I don't think you should worry too much
 
Cosmoline is a ***** to get off. I had a hell of a time removing it from the engine bay on my 300ZX. I used a citrus based degreaser (Xenit by Stoners) and it worked well. Lots of elbow grease needed though. You can try something like brake parts cleaner but you have to be very careful.
