Rust Free! ...Ahem

[techweenie]

Okay, but if the rusty parts are cut out, leaving only unrusted sheet metal, isn't that okay? Some advertisers think so.

[afterburn 549]

For those that do body work , we giggle when we hear the term "only Surface rust".
Once started it only eats in further from the surface.
Once rust starts, it is in quarantine , or arrest till it gets a opportunity .

I think there is bio-active something going on

Biogenic Magnetite Formation through Anaerobic Biooxidation of Fe(II)

Project – Super specialized Bio-active surfaces - Projects - Danish Technological Institute

quote from link
"In an iron- and silicate-containing solution, green sulphur bacteria, purple sulphur bacteria and purple non-sulphur bacteria are able to oxidise iron (II) to iron (III) compounds at 20˚ C. One representative of these bacteria, Rhodobacter ferrooxidans, was not discovered until 1993 and it was several more years before further papers were published on this bacterial species. In Tübingen, the bacterium has become a kind of pet project for Kappler's team of researchers. The findings obtained with R. ferrooxidans are a geobiological and geomineral breakthrough, and are so important that they will be included in fundamental science books. "The results open up a completely new understanding of early earth development and the ‘evolution' of atmosphere and hydrosphere," said Kappler.

If you actually read what you're quoting here (and understand it), you'll understand that what you're citing doesn't support your claim.

WRONG. Redox (look it up) reactions do NOT require oxygen to occur. All they require is two compound with different oxidation potential. Ever hear of galvanic corrosion? That's oxidation in which two thing in contact with one another have different oxidation potentials, and a reaction occurs. In the case of anaerobic oxidation, sulfur is often the oxidant. So, YES, oxidation can occur in an anaerobic environment.

Look man, I'm sorry that you don't know much about science, but my chemistry degree didn't come out of the back of a magazine. Rust isn't "alive", and doesn't require anything biological to occur.

You're missing a biology degree.

No, I'm not.

Let me google that redox thing for you:
Redox Reactions

At no point does the oxidation process require OXYGEN.
Oh all right, I will quote:
"An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron."

It's MAGIC, man!

On the flip side, a car like mine that spent its life baking in the desert southwest now needs every baked rubber bit replaced ... I guess that's better than rust.

Cheaper to fix, maybe, but that assuming you can get the rubber bits. Nice thing about steel, you can find that anywhere, and welding and forming it just takes money and time. Getting NLA rubber is a serious drag.

[Mick_D]

Try finding the tail rubber for a 75-77 Turbo tail sometime.

[Mick_D]

No it isn't. Carrera tail rubber won't fit. Tea tray rubber isn't the right rubber.

The only logical next question is: If rust is alive then does it have a soul?

It's not alive, and has no more soul than a fingernail clipping. But I think we'r headed into PARF territory on that one.

[Mick_D]

Maybe the new X-Files reboot will have an episode about rust being alive. It could happen.

I was being fesecious. I'm quite certain I never learned about the living rust organism in grad school. Dare is ask what PARF stands for? To get back on topic though, I do agree the term "rust free" is entirely abused and overused. I found that out the hard way with a recent episode involving a 75 911 with steel wide fenders.

PARF is the forum here on PP where logic and intelligence goes to die. Don't go there, it's a silly place.

And yes, I was also a little tongue in cheek, just playing along. You are correct - rust-free really has no meaning these days. It's just ad copy.

[kitesurfer2]

Simple. "Rust free"-

Means; You pay for the car and get the rust free.
