The place in Florida says the process removes cosmoline and doesn't harm rubber and plastic. How do people feel about this process and the results? Seems much less invasive than a brush and solvent. My belief was that the factory applied cosmoline to prevent rust during shipment. I'm not sure if the dealer was supposed to remove that as a pre-delivery prep, or if it typically was done.

After 30 years and 50,000 miles on a 911 I bought new, I frankly cannot tell what might be remaining cosmoline and what's built up road grim, minor oil and grease leaks and dirt. I'm not looking to get the car back to factory original to be trailered to shows. I would though like to have a clean suspension, undercarriage and engine compartment. Something that makes it a pleasure to do minor work, rather than have it all being a dull gray that falls on my face.

After further research on this site, it sounds like the consensus is that Tectyl is actually the preservative used by Porsche in recent years (that being 80s+). And the advice seems to be that if you strip the engine and underside to original finishes, it's prudent to apply some corrosion protection again, whether Tectyl or other product. Please give me your thoughts. thanks.

Here is an article that I found on Pelican:

Looks great, surprised that it plays well with rubber though...

PS what little I know about CO2 is that under the right pressure it takes very little temperature change for CO2 to change from a solid to a liquid to a gas.

and there is this article too:

Yes, Tectyl. If ever cleaning the underside or underside components I finish off with a light spray of Tectyl. Good stuff when dried off.

I did that to my 930 a few years ago. Went from an amazingly clean car to a show car in 1 day. Was the best investment I ever made.
