CT Corrosion

Ed,

Have you seen the numerous reports of stainless steel from the tesla cyber truck owners. Here is one today:

This doesn't appear to me to be a good application for stainless steel for numerous reasons.

The magnets form very tight crevices which are the worst for causing corrosion.
They trapped road grime and moisture, and this is what you get.
Rail cars made of 200 SS have been in service for decades, so it isn't the material per se.
What he did caused this.

CT owners have been complaining for months about other corrosion problems as well:

Some of the CT Owners are wrapping the "trucks" in vinyl for $6k wrap.

"Tesla uses 301 stainless which is a cheaper version of 304 stainless. 304 is what DeLorean initially used before switching to 316 for more corrosion resistance. It primary motivation is cost, and they'll be able to overcharge on the back end for brushing/restoring the stainless, Alex at YouTube/Legit Steet Cars has a series on what this process and the specialty tools look like."

What is the plastic that manufacturers wrap stainless steel with at the factory?

The picture is fake.

The photo is real. The video explanation is a lie. It is a printed vinyl wrap to make the truck appear corroded.

Okay that was a scam, but many others are complaining:

Supposedly "Ultra-Hard 30X Cold-Rolled stainless-steel" Others claim it is 301.

I expect it is a combination of not keeping carbon steel from contacting the panels during manufacture, not performing post-fabrication passivation, and surface contamination out in the wild causing rust nucleation spots.

Use a high quality paste wax, just like other vehicles require.

I like the idea that others tried and failed and, rather than figure would why the failed, Tesla would just do a similar thing on a large scale, expecting it to turn out differently.

No one buying these has any room to complain. They wanted a vehicle intended to be disruptive and they are finding out they are who is being disrupted. I have yet to see a single feature of this vehicle that isn't a disaster.

Do not use wax. Waxes will cause crevice corrosion. Use an acidic cleaner. Citric acid works well. If you want something in consumer packaging, boat wash products are typically oxalic acid based.

The corroded CT pic is obviously fake because it follows the corrosion patterns of a painted vehicle. The corrosion is mostly on the top which is the result of UV wear of the paint. There is no paint on the CT. There is also no staining on the black trim around the wheel wells.

Please learn to recognize fake images.
