Aluminum != Stainless (soft vs. hardened).

The 2B finish is the result of being rolled, so it is matte. While the stainless could be polished to get a uniform appearance, I doubt the original 2B could ever be exactly restored.

I'd like to think that the finished product will have a grained texture that is easier to maintain, but Mr. "best process is no process" will likely want to ship them as-is.
The CT I saw at the Peterson definitely 100% was polished. I included some images below from my visit. There were a lot of swirls on the hood. I imagine that even just using a rag to get the road dust off would leave minor swirl scratches. You can clearly tell that they were testing some different levels of polish and couldn't get them to match on the passenger side doors. I was a little surprised that they presented it like that.

I guess they're experimenting with different finishes? That's a decision that can wait until about 5 minutes before they start building, so we probably won't hear anything about it from Elon until the first-ship-date approaches.

What I am really scared of is, while parked somewhere, in a mall for instance, finding the car with a lot of scratches. Just because of stupid people trying to scratch "this new material" for fun :confused:
That's why I am thinking of a custom cover. Any ideas?

If you want to blend in so nobody will notice it,
when parked put a custom cover on the Cybertruck that makes it look like a Ford F-150 ICE.

Alternative is hologram projection image of Ford F-150 ICE.

Thinking about it a little more you could blend in easy using a Ford F-150 Lightning image too. They all look the same.

I wonder if Tesla expected the Cybertruck to be

I'm not sure what you are talking about, the Cybertruck blends right in.

Very good but somethings are missing.
1. Cybertruck is too clean
2. Cybertruck has no skulls and other stuff.
3. Maybe if you add a big V type snow plow blade or a train steam engine locomotive cow catcher/diverter on front of Cybertruck?

Not my Photoshop job, I stole it. Probably ought to have a guy with a harpoon gun in the bed of the Cybertruck to really blend in.

1) It's stainless.
2) The Road Warrior's and the 'good guys' never had non-utilitarian stuff on their vehicles.
3) That's for the revenge sequence.

Come on guys. Its missing a tesla coil in the bed. Harpoons are so 90s. Unless you were thinking electromagnetic railgun harpoon with electrified tether. Then I suppose you are on the right track.

I’m still pinching myself that the monocoque exoskeleton will be manufactured out of extremely durable 3mm thick stainless steel. The body should last 100+ years before it’s recycled for new sinks, dishwashers, refrigerators, commercial kitchen equipment, etc.

The Cybertrucks stainless steel won't be recycled into appliances unless by 'recycled' you mean refined back into base metals for re-use. The cold-rolled stainless will be a completely different product than what appliances are made of. Appliances scratch really easily, they are made of very soft stainless compared to the alloy and hardening process the truck will be fabricated from.

I was watching a recent interview with Elon and he elaborated a bit on how they selected the metal for the Starship. Previously, Elon had alluded that the Cybertruck might use the same metal. It turns out, SpaceX didn't really 'select' the metal for Starship as much as they developed a new alloy variation. Elon said it's a specially formulated alloy that requires a special mill run every time they want to buy more. Whether Cybertruck will be this exact alloy, a normal mill run alloy or a variation specially designed for Cybertruck remains to be seen. But we know for certain it will be cold-rolled multiple times to make it tougher than the alloy (whatever it is) would be without roll-hardening. Roll hardening retains the ease of welding of this class of stainless steels while making it much tougher. The downside is that it becomes so hard it can no longer be formed by stamping, it needs to be scored and folded on an industrial metal brake. Hence the flat shapes of the Cybertruck. This will be 3 mm thick (about 1/8") which puts it on the dividing line between what whould be called "sheet metal" and
"metal plate".

Roll hardening aligns the grains of metal to be progressively stronger the more times it is passed through hardened steel rollers with many hundreds of tons of pressure at room temperature. The strength gained by roll-hardening has a directional nature to it. This means Tesla will cut the components of the Cybertruck from the sheets relative to the direction of the roll-hardening. This will be necessary to control the quality and uniformity of the resulting panels. Without doing this there would be no consistency in the final parts. It can also be taken advantage of by laying out the components so the strength is maximized in the directions required. I'm heartened that the steel will come from a brand-new mill near the factory using new, state-of-the-art rolling equipment. This will greatly ease the difficulty of manufacture and increase the quality and consistency of the finished products.

The difference in strength and toughness of 301 and 304 series stainless steel when full soft (as in most kitchen appliances) and cold-rolled to various levels of hardness should not be under-estimated. Cold rolling can more than double the tensile strength and more than quadruple the yield strength without adding any weight to the material when compared to the common annealed versions. Increasing the hardness by cold-rolling also increases surface hardness by up to 2-3x.

It will be exciting to learn exactly which alloys and hardness levels Tesla selects for the Cybertruck. Will the alloys be custom or regular mill run alloys? It's highly likely, given Tesla's tendency to optimize materials for the design, that they will use different alloys and hardness levels for different components to suit the desired characteristics.

Yes, I meant refined into base metals.

Tesla’s proprietary stainless steel alloy is my #1 reason for pre-ordering the Cybertruck. I still pinch myself that Tesla’s SS wedge is actually going into mass production next year. I can finally say goodbye to annoying door dings and paint chips:)

So when do me see a metric gauge?

Doing some work around the house and wound up cutting some 1/8 inch steel plates. It is pretty burly stuff, thicker than most old school bumpers. Shopping carts and car doors will scratch the surface, but there won’t be any dings. Not sure how it’ll fair if someone backs into it, take more than just a little kiss and far more likely to damage their car.

For crumple zone reasons I predict that that the hood and front fenders will be thinner than 3mm in order to achieve a frontal 5-star crash rating.
