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.

    Stainless doesn’t rust. Stainless alloys do. Lives are an alloy because they need certain properties to be able to sharpen them properly and hold an edge.

    Medical stainless doesn’t rust and whatever the hell my kitchen sink is doesn’t either.

      “Surgical” stainless - a marketing term - will rust simply because it’s still an alloy of chromium and steels - it just takes far longer than the higher carbon steel alloys because of the lower carbon content. And yes, scalpel blades are made from high carbon stainless alloys that WILL rust if not properly stored - they are single use items and tossed when done being used once.

      Your stainless sink is probably made from some 304 stainless alloy due to it’s deep draw properties thanks to the extra nickle content. Things marked “Surgical” stainless would fall into this type of alloy. But 300 series stainless steels still contain about .05% carbon which is still enough to cause eventual rusting or staining.

        You do know that more than scalpels are used right? Things that are put into autoclaves and used over and over and over again.

      Good knives rust, bad knives don’t. You need high iron to hone a perfect edge properly. You can still resharpen a shitty knife, your grocery butcher will likely do it for free, but it will never have the same edge as a properly honed good knife.
