Dad used olive oil iirc or maybe peanut to season the wood stove..
only wish he'd have taken the woodstove outside to heat up and cure the oil.
smoked us out for a day or 2..

Your getting there.
One more good soaking & cooking just might do it

Looking good.
Way too busy today to slap around the peanut oil...Ospho and paint had my attention.
Hopefully this week at some point. |

Now, as most exhaust systems rot from the inside out, at least non-stainless ones, perhaps there would be a way of getting the inside coated as well. Maybe pour peanut oil into the throttle body? I'm joking.
I suppose the OP really only wants to keep the non-stainless flanges from deteriorating.
Some reading for you:

[quote="Andrew A. Libby _
13 years later, can you report on the effectiveness of the treatment? How often did Tube reapply the oil? Was it an effective long-term solution that prevented rust entirely? Was it low-maintenance or high-maintenance?[/quote]
Toady, I had the pleasure of spending some time with Mike Popovich (aka The Tube Guru). While shooting the shit with him, I mentioned the renewed interest in the Peanut Oil Exhaust Pipe Treatment on TheSamba.com. The first words out of his mouth were, "That really worked."
Initially, Mike said he applied it several times over a period of about a month. Then he would re-treat the pipes each spring after the winter had had its way with them.
Starting in 2003 he ran the van until he sold it in late 2010, never needing ANY exhaust work. At that time, he said the pipes were solid and still looked good . He said, in particular, he liked the rich patina that developed on them with successive treatments.
One thing about Mike is that he is as forthright and precise in his manner and words as the day is long. In other words, he is not full of shit.
That's all I can say about the efficacy of the Peanut Oil Exhaust Pipe Regimen.

Would this work on an cast iron exhaust manifold or would it
A) get too hot
B) be a waste of time since the manifold ain't rusting away any way
The analogy of seasoning a cast iron skillet as to steel pipes isn't exactly clear cut. A Cast iron skillet has more pores than a extruded steel pipe. Not saying it won't work, just way different properties between the two, that's all.
How come I'm craving bacon and cornbread now?

Depends upon the quality of that cast iron frying pan.
Grab a Wagner high quality pan vs. a Walmart made in bombay pan.
You'll find that the Wagner casting is a far slicker casting in comparison to the cheaper unit, and at 4-5 times the cost.
They both require seasoning, the finer casting Wagner pan will take less.
The headers of a Vanagon?
Might get too hot in the head areas and require more seasoning to get the job done, but it will work.
Pretty much just as Richie mentioned.

Thanks Richie, very helpfull!
So his "documented" way of application is to do it several times (how many times?) in a period of a month (several drives/heat cycles per coating) the first year, then only once every year after that.
I did a generous coating 3 times with drives in 3 days.
Now we will see how it works with my old rusted pipe after this winter.

Forth, my man, I think you need to put down your Shiner, climb off of your stool at Billy Bob's and spend the coming winter within 500 miles of the big lake they call Gitche Gumee. You'll soon come to realize that in the brutal North, an exhaust system doesn't survive long enough to rust from the inside out.
I can't count how many times I've seen a slip joint exhaust system where at a joint the female end was so wasted away from corrosion that it could be peeled off like a tuna can lid while the mating (and protected) male pipe end was rock solid.
Add a healthy spray of salt solution to the mix of heat cycling, vibration fatigue and embrittlement, and a Vanagon exhaust system doesn't stand a chance.

OTOH: If your muffler is rusting from the inside, you're probably only drive short distances
and rarely get it hot enough/long enough to burn the moisture out of the cold system.
Best solution for this scenario (other than taking the long way to work) is to punch 3 or 4
nail holes in the bottom of the muffler to allow accumulated moisture to drain. Try it on
your next new muffler...cheap and effective.

Perfect. Salty roads up your way for sure.

VW gas in-line 4 exhaust manifold actually, will sit at the 50 degree orientation - probably too hot, eh?
You still didn't answer the important question about bacon and corn bread.  (Actually, we have a vintage cast-iron corn bread roll pan - makes about 10-12 1/2 cylinder corn breads.)

It gets pretty hot right at the ports of the exhaust manifold.
While I have mopped down the pipes on a 1.9 I had years ago, they didn't get any worse than they initially were.
Your findings & results may vary.
Try it out, see what happens, it isn't an expensive or difficult task, give it a trial and report back on your findings.
This would be the fastest way for the answer your seeking.

Yeah, I wasn't born a Texan, but I didn't waste any time getting here! (Well, I sorta did. Took me about 22 years in the service, first) I was actually born and raised in Cleveland, OH. The middle of the "Rust Belt".
I do remember replacing 2 year old exhaust systems in teacher's cars to raise money for the High School Auto Shop. Also, tin cans and bailing wire for my cheapskate and broke friends. A little later, I worked at a service station (back when gas stations only sold food in vending machines), so I had a discount and access to all the cool tools.
So, yes, while there is a level of rot that comes from the inside of a standard steel exhaust system, the ratio of outside-to-inside corrosion would, depend on the environment. More so, in your neck of the woods.
Shiner=Yes. Billy Bob's=Noooooo.
