Despite the recent release of these Tesla EVs — and the little road time they’ve been subjected to — Cybertrucks are already developing imperfections on their body panels, leading owners to debate what’s causing the early signs of rust on forums. From Futurism:
One Cybertruck Owners Club forum member says they started noticing small orange flecks appearing on his truck after driving it in the rain for just two days.
“Just picked up my Cybertruck today,” they wrote. “The advisor specifically mentioned the cybertrucks develop orange rust marks in the rain and that required the vehicle to be buffed out.”
The Cybertruck owner posted followup photos after washing the vehicle down with soap, and they didn’t inspire much confidence, showing body panels already pockmarked with small orange spots.

Knifes are different though, as that is a different stainless steel alloy. I don’t remember the specifics, but something about higher carbon content so it can be hardened? This is why you shouldn’t put knifes into a dishwasher, they don’t like the salt and will get pitted over time.
Nevertheless, no “normal” stainless is actually immune to rust or general corrosion anyway. It also depends on the environment (ask boat folks about this one), specifically if oxygen can get to it. And salt just makes everything 100x worse, too.
Closest you get to real rust proof steel is nitrogen steels, which are used for diving knives. Super super hard though, doubt it’d make a good auto body, I’d imagine such a thing would be prone to cracking. Expensive too. I’m gonna say Daddy Elon’s best bet is to slap regular painted body panels on it and take the hit. I think we all know what he’s not going to do though.
Even the nitrogen alloy steels used for diving knives will corrode. It just takes a lot longer than the normal high carbon stainless alloys.
Water is the universal solvent…
If/when BYD builds their first manufacturing plant and starts selling, Musk might change his mind about that.
