07 Stang

This is something I discussed a few months ago. On many Ford parts you buy it will say this;

409 stainless has excellent forming characteristics and is rust through resistant.
A surface rust will form in most instances. This rust retards further corrosion.

So whatever you do, don't try to wire brush it off. You'll just make it worse. Some guys in the Military say the ships and some parts are like that.

i also have a rust problem and was hoping someone can help me out with it. ihave had my car for a month and a half , bought brand new. Last week when i was washing it i noticed little rust spots on the trunk lid. can someone pleasetell me what i should do about this.

This is what you do...
Rust proof it with POR15.

This rust (the brown on the axle) is what I think of as normal surface rust. Like 07Stang says, it forms a protective coating (I hope!)

Surface rust is not protective budd[&:].It will keep rusting until nothing's left. If it was the case, cars from the 60s or older would still be around.

The metal is too thick on our rear axle for it to desintegrate within the life time of our Mustangs. So Ford gets away with this.
I'm sure DD Stangs up North, will have pitted axles in5 years or so. It will still work fine, just look like sh#t.

Pascal, you're right in that "protective" was probably not the best word for me to use, and it's true the classic cars were just too thin to withstand corrosion. I was referring to the outer layers of rust on thicker unpainted metal structures like some old bridges (and hopefully car axles.) The outer layers of rust would inhibit corrosion of the inner layers of the metal. If you google terms like "protective rust" and "bridge" you'll see what I was referring to. I wish I knew more about it, and I wish I could say for sure it works on our axles!

I'm glad you didn't jump at my throat.

Even though I work on cars for a living and havedrestored a bunch of Classics, I sure don't pretend to know it all, since I never will anyway...[8D]

We shouldn't worry about our axles. They will not rust out through anytime soon. It will take a long while to see holes through them[8D].
As far as layers of rust, once the first onehasconsume the metal, the next one takes over, and so on, until it's gone.
The process is slower than a bare metal piece. It takes about 10 minutes for bare metal to rust when it has beenexposed to water (a lot longer if it stays submerged). Water and air (oxygen) isa lethal combination, add salt, and it gets even worse. Butwe all know that.

As far as bridges, they use treated metal nowadays and I'm not up on that technology, so I won't say more.
I know that the G. Wash. or Brooklin ( I forget) bridge in NYC has rusting and fatigue issues and we're not talking sheet metal here[8D].
Then again, back when they built those, the metallurgy wasn't as good as quality as today.

Pascal, what you say makes perfect sense to me. Did you do any special prep before using the POR-15?

Brian, what did you paint your axle with? It looks good.

not my car some guy did the preping andrust proofing go to http://www.mustang-gtcs.info/mods01.htm
