Had my new to me 71T dry iced last month & wanted to share the results. I went through Dry Ice Werks in Grass Valley, CA. Jurgen did an excellent job on the car! He uses a specialized machine from Germany that can dial down the pressure when needed. Delicate enough to be used on touchscreens! He is very aware of sensitive areas under longhood cars. While also keeping as much originality possible.

Excellent result.
Dry ice blasting (at higher pressures) can also be used for removing paint. Here:

It's German-speaking but in the settings of the YT vid, the subtitles can be set to Auto-translate to English.
Looks great and effective but, I’ve read that it removes the cosmoline. Looks to be case here. Are you going to have that re-applied for general water protection?

It will if the pressure is dialled up too high but I have had a car done where cosmoline stays intact.
Depends on the equipment in use and the skill of the user.

Jurgen gives you options. The existing cosmoline coverage wasn’t great which was to be expected. So it’s a personal preference if one believes the cosmoline has run its course. Car is parked on a lift & I’m quite meticulous when it comes to keeping the car clean & protected. I assume coastal weather or northern climates play a large factor to what kind of protection folks use. Luckily I’m in a dry climate & the car won’t see any rain. If it does, the car goes up on the lift & underside can easily be detailed.
That’s good to know! When I finish my car, it’s going to get a fresh spray of cosmoline under there. Even though I’m in the same climate. My car WILL see rain when driving, lol.Originally Posted by BOYER73S

Fortunate to have several Porsche options for inclement weather. I’ll make sure to update how the car is holding up in 10 years / 30k miles.
All I can say is that what we find hard to do now is reproduce the quality of the coating ,paint and anodising that Porsche did 50+years ago.
