I hope Tesla seriously entertains a brushed finish for its 3mm thick stainless steel exoskeleton. If the production Cybertruck‘s looks similar to the concept it will not have a finished look IMHO. When I viewed the truck in person at the Peterson Museum I couldn’t help think how much sharper and production ready the CT would look with a brushed finish.

If I had the computer talent I would post a rendering of two Cybertruck‘s side by side. One with the current finish (2B) and one with a brushed finish (No. 3 or 4).

No. 8 (Mirror)
No. 4 (Brushed, 150 Grit)
No. 3 (Brushed, 120 Grit)
2B (Bright, Cold Rolled)

I am fine with anything, but prefer anything but #8

You guys are still way overthinking this stuff. It's not that complicated. It's not rocket science. It's not going to be life-or-death flying in the air and one cracked weld results in the deaths of a couple hundred people. It's not aluminum. It's cold rolled stainless steel and quite thick too. I don't even want to call it sheet metal, it's more like plate. You get a competent welder and it will hold a ladder rack with quite a few ladders, no problem whatsoever.
The location and preparation for something like a winch... I'd bet Tesla has thought of that and prepped it at least a bit.
Like I've said before, just slap a sticker, "Sanford and Son" on the door, and call it a day.
It is not rocket science, but it is still welding. Considering the broad range of impacts that welding can cause (everything in between a 5mm long 40A TIG and a 200mm long 200A MAG weldseam), Tesla would be quite dumb to "allow" welding on the structure they take responsibility for. Drilling holes is much easier to define than welding. We should be glad to get at least permission to do that to vehicles that should be kept save and street-legal.

I am a little worried hearing, that 304L will be the material of choice. The chemical resistance seems not very promising. A material which can handle salt like 316L should be the least. I was hoping, that the X in 30X conceales a little bit of magic, but 304L is not much better than 301.
If the durability of the CT is just given in desert climate, I would be quite disappointed.

Elon lives in a salty-air environment. It is hard to imagine him not being sensitive to salt-induced corrosion.

I'm more interested in why they're focusing on using a specific steel product and raising the demand for it.

I wonder if there's a grading process any a certain number of steel blanks are expected to fail qualification for Starship and this gives a good second market for those good-but-not-perfect pieces? If you make 1000 pieces, and you need 10 to be perfect, it's easier and cheaper to have a market for the other pieces than to have to recycle them.

Tesla/Space X seems to always operate in 'always make one stone do at least two moves' Go thinking.

I am blown away that the CT will use 3mm thick SS for the exterior. This blows the competition out of the water.

I really don’t care about the grade of SS. I am just praying that they keep the 3mm thickness specification. Tesla was considering 4mm thick SS but the doors would have gone from 60 to 90 pounds.

That’s pretty amazing to think about that.

If the newly formulated SS is good enough for the Space X Starship that will travel to Mars it’s good enough for my earthbound Cybertruck. This truck is going to be off the hook!!!
