Rust Spots/Corrosion is the Norm

[Bartman]

I think as long as you don't drive it in the rain, or get it wet, it will be fine.....

Here is another product that may be worth exploring.

(BTW: I tested the black oxide on Martensitic stainless and it works but seems to accentuate any surface flaws so it is aesthetically sub optimal.)

I still am concerned with the concentrated anode effect of any organic coating on stainless that could lead to pitting. Superhydrophobic coatings may still be worth investigating in so far as keeping water out will result in less galvanic action. Cheers.

Yes, agree that the 3M product looks like a decent bet. Really there are several SS products that are pretty good. (other than windex)

You must feel personally threatened by the Cybertruck in order to pretend that a Cybertruck might look like this if you leave it outside and don't laboriously protect it.

Or maybe you are just that gullible.

What’s interesting y’all haven’t started to talk much about salt

To avoid rusting, apparently the owners manual warns of the need to wash off salt after driving in it. A main reason I ordered the CT was to not have to worry about road salt. Body's bullet proof but don't let salt get on it? Am I buying a summer truck?

All vehicles corrode with exposure to salt and water. The Cybertruck body is far more corrosion resistant than any traditional vehicle with painted mild steel sheet metal.

As to the corrosion resistance of the rest of the Cybertruck, only time will tell. But I think it will be better than traditional steel frames. The only ways it could be worse is if it has a design flaw in terms of the mating of dissimilar metals or stray electrical current, either of which is certainly possible but not very likely because we know these factors would have been looked at in a very detailed manner.

However, it's the height of ridiculousness to pretend that the stainless body panels of the Cybertruck will probably be more problematic than painted mild steel. People are trying to throw shade here by leveraging the fact that the average truck buyer knows very little about metallurgy and corrrosion. The stainless panels are one of the greatest differentiators of the Cybertruck relative to the thin, soft and rust prone panels of traditional trucks, and Tesla detractors are trying to blunt the very significant advantages of this by throwing fear, uncertainty and doubt at the stainless panels.

It's different, so it must be worse, right? This is going to be a big problem.

This guy say always, always nano-coat your metallic skins to prevent rusting/excess corrosion. With an iron-based suit, you'd think he'd know.

Your points are all fine, and some people are definitely coming at this from the wrong place... But you do have to realize, 2 people posted little rust spots. It is going to generate some questions. If you don't know that rust stains can happen to basically any material, it's going to be something you ask questions about.

I can also cause car paint, concrete, aluminum, and titanium to "rust" in the same way, in that the surface is stained by another material touching it while rusting. But if I didn't know that, I'd probably be confused as well and start asking questions.

It's also important to note, that little non structural rust spots on the underneath/backside of painted body panels are not as big of a deal as rust spots on the exterior surfaces of a vehicle. If you wouldn't expect to see rust in ~10 years on a painted car, yeah, it can be a little nerve wracking to see people talking about rust on the cybertruck in ~ 10 days.

Just don't assume everyone is coming at this from a position of "ridiculousness", is all I'm saying. People are allowed to ask questions about such a big purchase, as long as they're willing to listen to the answers and not jump to conclusions.

What the heck are you talking about?

The rust shown in the photos is not the Cybertruck rusting, it's particles containing iron that landed on the Cybertruck and rusted when they got wet. This is very common on painted cars and trucks too, brand new ones even, especially light colored ones, and it can be cleaned off more easily and completely from the ultra-hard stainless steel of Cybertruck than from the soft, damage prone paint on legacy trucks. It will not return unless new iron-bearing particles land on the surface again, just like on any car or truck.

That's why I said it's people trying to throw shade on Cybertruck based on the fact that some people are too ignorant to know it has nothing to do with the stainless steel. It's fear, uncertainty, doubt and ignorance being leveraged here. This is not a complex or confusing phenomenon we are looking at here.

Due to the iron content, it can be difficult to clean stainless steel of stains of blood.

Or so I'm told

Here in Los Angeles, mine has been in and out of the rain for the past few days and is showing no signs of anything problematic. Not saying it's not possible, but seems like another compound got on it (like rail dust). Like when you wash your all clad pots in the dw with some cheap metal and the rust deposits itself into the finish.

Unbelievable how gullible people can be. My stainless steel BBQ sat outside in the yard for the past 15 years and not a single spot of rust on it. Simply wow….

tiny little flaw in your mike drop: there are many of types of SS, each with different behaviors and strengths/weaknesses in terms of performance in different use cases, which result from compromises made in one metric to achieve results in other metrics.

and in this specific case, the people building your grill likely had a primary and easy to achieve performance metric.

meanwhile, historically, there is a reason this family of materials was named stainless, not stainfree.

in short, for these reasons, what seems “gullible” if anything is thinking that your experience with your BBQ grill in your back yard forecloses all reasonable inquiry into how a Cybertruck will behave in all use cases across the country.

I wonder: did your BBQ grill manufacturer offer you an additional product to use to “seal” your grill to prevent staining and corrosion?

because that’s what Tesla will be offering for the CT

 

[SentinelOne]

My BBQ is only a 1 seater and won't do 0-60 in 2.6sec so the CB better be Stainfree!

Jokes aside, personally I have a touch of OCD and rust bothers me so I can see people getting on edge with posts like this. eg early signs of not being 1000% rust free. Reality is it's no metal is going to be perfect in every aspect (compromise). I'm sure Tesla came up with the best mix possible and it'll be better than mild painted steel by a long shot!

 

[DumpsterFire]

This has got to be one of the more ridiculous threads I’ve read on this MB…
